Warrant to Purchase Up to 1,350,000 American Depositary Shares

Up to 1,350,000 American Depositary Shares Representing 135,000,000 Ordinary Shares Issuable Upon Exercise of the Warrant

Kazia Therapeutics Limited

This prospectus relates to the offering and resale by Alumni Capital LP (“Alumni Capital” or the “Selling Shareholder”), of up to 8,850,000 American Depositary Shares (the “Offered ADSs”) with each American Depositary Share (“ADS”), representing 100 of our ordinary shares, no par value per share (the “Ordinary Shares”), or 885,000,000 Ordinary Shares in the aggregate, which includes up to 1,350,000 ADSs, representing 135,000,000 Ordinary Shares, issuable upon the exercise of a warrant (the “Warrant”) to purchase ADSs.

The Offered ADSs being offered by the Selling Shareholder have been or may be issued and sold to the Selling Shareholder pursuant to the purchase agreement, dated April 19, 2024 (the “Purchase Agreement”), that we entered into with Alumni Capital. See “The Alumni Capital Transaction” for a description of the Purchase Agreement and “Selling Shareholder” for additional information regarding Alumni Capital. The prices at which Alumni Capital may resell the ADSs offered hereby will be determined by the prevailing market price for the shares or in negotiated transactions. We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of Offered ADSs by the Selling Shareholder. However, we may receive proceeds of up to $15.75 million from the exercise of the Alumni Warrant and the sale of ADSs to the Selling Shareholder pursuant to the Purchase Agreement, once the registration statement that includes this prospectus is declared effective.

The Selling Shareholder may sell or otherwise dispose of the Offered ADSs described in this prospectus in a number of different ways and at varying prices. See “Plan of Distribution” for more information about how the Selling Shareholder may sell or otherwise dispose of the Offered ADSs being registered pursuant to this prospectus. The Selling Shareholder is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act of 1933, as amended.

The Selling Shareholder will pay all brokerage fees and commissions and similar expenses. We will pay the expenses (except brokerage fees and commissions and similar expenses) incurred in registering the ADSs, including legal and accounting fees. See “Plan of Distribution.”

The ADSs are listed on the Nasdaq Capital Market, or Nasdaq, under the symbol “KZIA.” On December 2, 2024, the last reported sale price of the ADSs on Nasdaq was $5.00 per ADS.

We are a “foreign private issuer”, as defined under the federal securities laws, and, as such, we will be subject to reduced public company reporting requirements for this prospectus and future filings. See “Prospectus Summary—Implications of Being a Foreign Private Issuer.”

ABOUT THIS PROSPECTUS

The Selling Shareholder named in this prospectus may resell, from time to time, in one or more offerings, the Offered ADSs. Information about the Selling Shareholder may change over time. When the Selling Shareholder sells Offered ADSs representing Ordinary Shares under this prospectus, we will, if necessary and required by law, provide a prospectus supplement that will contain specific information about the terms of that offering. Any prospectus supplement may also add to, update, modify or replace information contained in this prospectus. If a prospectus supplement is provided and the description of the offering in the prospectus supplement varies from the information in this prospectus, you should rely on the information in the prospectus supplement.

Neither the delivery of this prospectus or any prospectus supplement or any issuer free writing prospectus nor any sale made hereunder shall under any circumstances imply that the information contained or incorporated by reference herein or in any prospectus supplement or issuer free writing prospectus is correct as of any date subsequent to the date hereof or of such prospectus supplement or issuer free writing prospectus, as applicable. You should assume that the information appearing in this prospectus, any prospectus supplement or any document incorporated by reference is accurate only as of the date of the applicable documents, regardless of the time of delivery of this prospectus or any sale of securities.

Before purchasing any securities, you should carefully read both this prospectus and any accompanying prospectus supplement, together with the additional information described under the headings, “Where You can Find Additional Information” and “Incorporation of Documents by Reference,” respectively, of this prospectus. Unless otherwise indicated or the context implies otherwise:

We effected an ADS ratio change to change the ratio of ADSs to ordinary shares from one ADS to ten Ordinary Shares to the new ratio of one ADS to one-hundred Ordinary Shares (the “ADS Ratio Change”) on October 28, 2024. The amounts and sales prices of the ADSs disclosed in this Post-Effective Amendment No. 1 have been adjusted to reflect the effect of the ADS Ratio Change, except for such amounts and sales prices of the ADSs that were sold prior to October 28, 2024, unless otherwise expressly indicated.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein contain statements that are not historical facts and are considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act, Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that involve substantial risks and uncertainties. All statements other than statements of historical fact, including statements regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans and objectives of management, are forward-looking statements. In some cases, you can identify forward-looking statements by the words “could,” “believe,” “anticipate, “ “intend, “ “estimate, “ “expect, “ “may, “ “continue, “ “predict, “ “potential,” “project, “ or the negative of these terms, and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, levels of activity, performance or achievements to be materially different from the information expressed or implied by these forward-looking statements. Although we believe that we have a reasonable basis for each forward-looking statement contained in this prospectus and the documents incorporated by reference herein, we caution you that these statements are based on a combination of facts and important factors currently known by us and our expectations of the future, about which we cannot be certain.

Forward-looking statements include, but are not limited to, statements about:

We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in this prospectus and documents incorporated by reference herein, particularly in the section titled “Risk Factors,” in this prospectus and in our Annual Report on Form 20-F for the fiscal year ended June 30, 2024, which is incorporated herein by reference

that we believe may cause our actual results or events to differ materially from those expressed or implied by our forward-looking statements. Moreover, we operate in a competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this prospectus. As a result of these factors, we cannot assure you that the forward-looking statements in this prospectus will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all.

All forward-looking statements speak only as of the date of this prospectus or, in the case of any prospectus supplement, any free writing prospectus, or any document incorporated by reference, that prospectus supplement, free writing prospectus or document. You should not place undue reliance on these forward-looking statements. Although we believe that our plans, objectives, expectations and intentions reflected in or suggested by the forward-looking statements we make in this prospectus are reasonable, we can give no assurance that these plans, objectives, expectations or intentions will be achieved. Important factors that could cause our actual results to differ materially from our expectations are disclosed and described under “Risk Factors”, elsewhere in this prospectus, any prospectus supplement, any free writing prospectus and in filings incorporated by reference.

The forward-looking statements made in this prospectus relate only to events or information as of the date on which the statements are made in this prospectus.

RISK FACTORS

Investing in the ADSs involves a high degree of risk. You should carefully consider the risks described under “Risk Factors” in our Annual Report on Form 20-F for the year ended June 30, 2024, as filed with the SEC, and all other information contained in, or incorporated by reference in, this prospectus, as updated by those subsequent filings with the SEC under the Exchange Act, before making an investment decision. The risks and uncertainties described below and incorporated by reference are not the only ones we face. Additional risks and uncertainties not presently known to us may also adversely affect our business. Our business, financial condition and/or results of operations could be materially and adversely affected if any of these risks occur, and as a result the trading price of the ADSs could decline and you could lose all or part of your investment.

This prospectus also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements.” Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors.

Risks Related to this Offering, Our Ordinary Shares, and the ADSs

It is not possible to predict the actual number of ADSs we will sell under the Purchase Agreement to the Selling Shareholder, or the actual gross proceeds resulting from those sales.

Subject to certain limitations in the Purchase Agreement and compliance with applicable law, we have the discretion to deliver notices to the Selling Shareholder at any time throughout the term of the Purchase Agreement. The actual number of ADSs that are sold to the Selling Shareholder may depend based on a number of factors, including the market price of ADSs during the sales period. Actual gross proceeds may be less than $15.75 million, which may impact our future liquidity. Because the price per ADS sold to the Selling Shareholder will fluctuate during the sales period, it is not currently possible to predict the number of ADSs that will be sold or the actual gross proceeds to be raised in connection with those sales.

Investors who buy ADSs in this offering at different times will likely pay different prices.

Investors who purchase ADSs in this offering at different times will likely pay different prices, and so may experience different levels of dilution and different outcomes in their investment results. In connection with the Alumni Capital Transaction, we will have discretion, subject to market demand, to vary the timing, prices, and numbers of ADS sold to Alumni Capital. Similarly, Alumni Capital may sell such ADSs at different times and at different prices. Investors may experience a decline in the value of the ADSs they purchase from the Selling Shareholder in this offering as a result of sales made by us in future transactions to Alumni Capital at prices lower than the prices they paid.

The issuance of ADSs to the Selling Shareholder may cause substantial dilution to our existing shareholders and the sale of such ADSs acquired by the Selling Shareholder could cause the price of the ADSs to decline.

We are registering for resale by the Selling Shareholder up to 8,850,000 ADSs. The number of ADSs ultimately offered for resale by the Selling Shareholder under this prospectus is dependent upon the number of ADSs issued to the Selling Shareholder pursuant to the Purchase Agreement. Depending on a variety of factors, including market liquidity of the ADSs, the issuance of ADSs to the Selling Shareholder may cause the trading price of the ADSs to decline.

The sale of a substantial number of the ADSs by the Selling Shareholder in this offering, or anticipation of such sales, could cause the trading price of the ADSs to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire.

9

The market price of the ADSs has been and will likely continue to be volatile and you could lose all or part of your investment.

The market price of the ADSs has been and may continue to be highly volatile and could be subject to large fluctuations in response to the risk factors discussed in this section, and others beyond our control, including the following:

In addition, equity markets in general and the market for biotechnology and life sciences companies in particular, have experienced substantial price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the companies traded in those markets. Further changes in economic conditions in Australia, the U.S., EU, or globally, could impact our ability to grow profitably. Adverse economic changes are outside our control and may result in material adverse effects on our business or results of operations. These broad market and industry factors may materially affect the market price of the ADSs regardless of our development and operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs and divert management’s attention and resources.

If the market price of the ADSs falls and remains below $5.00 per share, under stock exchange rules, our shareholders will not be able to use such ADSs as collateral for borrowing in margin accounts. This inability to use ADSs as collateral may depress demand as certain institutional investors are restricted from investing in securities priced below $5.00 and may lead to sales of such ADSs, creating downward pressure on and increased volatility in the market price of the ADSs.

If we cannot meet Nasdaq’s continued listing requirements, Nasdaq may delist the ADSs, which could have an adverse impact on the liquidity and market price of the ADSs.

The ADSs are currently listed on the Nasdaq Capital Market. On November 20, 2023, we received a letter from the Listing Qualifications Staff of Nasdaq notifying us that, for the previous 30 consecutive business days, the bid price for the ADSs had closed below the minimum $1.00 bid price per share requirement for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2). Under Nasdaq Listing Rules, we had 180 calendar days from the date of the notice, or until May 20, 2024, to regain compliance with the minimum bid price requirement, during which time the ADSs continued to trade as normal on the Nasdaq Capital Market.

On May 22, 2024, we received a letter from Nasdaq notifying us that, while we have not regained compliance with the minimum bid price requirement, Nasdaq has determined that we are eligible for an additional 180

10

calendar day period, or until November 18, 2024, to regain compliance with the minimum bid price requirement. If at any time before November 18, 2024, the bid price of the ADSs closed at or above $1.00 per share for a minimum of 10 consecutive business days, we would regain compliance with the minimum bid requirement. Nasdaq’s determination was based on us meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and our written notice to Nasdaq of its intention to cure the deficiency during the second compliance period and, if necessary, by effecting a ratio change of the ADSs to its ordinary shares.

On October 28 2024, we effected an ADS ratio change to change the ratio of ADSs to ordinary shares from one ADS to ten ordinary shares to the new ratio of one ADS to one-hundred ordinary shares. On November 12, 2024, we received a written notification from Nasdaq informing that we have regained compliance with the minimum bid price requirement.

We cannot assure you that we will remain in compliance with all applicable requirements for continued listing on the Nasdaq Capital Market. If we fail to sustain compliance with all applicable requirements for continued listing on the Nasdaq Capital Market, the ADSs may be subject to delisting by Nasdaq. This could inhibit the ability of holders of the ADSs to trade their ADSs in the open market, thereby severely limiting the liquidity of such ADSs. Although holders of the ADSs may be able to trade such ADSs on the over-the-counter market, there can be no assurance that this would occur. Further, the over-the-counter market provides significantly less liquidity than Nasdaq and other national securities exchanges, is thinly traded and highly volatile, has fewer market makers and is not followed by analysts. As a result, your ability to trade or obtain quotations for these securities may be more limited than if they were quoted on Nasdaq or other national securities exchanges.

Raising additional capital may cause dilution to our existing shareholders, restrict our operations or cause us to relinquish valuable rights.

We may seek additional capital through a combination of public and private equity offerings, debt financings, strategic partnerships and alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity, convertible debt securities or other equity-based derivative securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as holder of ADSs. Any indebtedness we incur would result in increased fixed payment obligations and could involve restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any debt or additional equity financing that we raise may contain terms that are not favorable to us or our shareholders. Furthermore, the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of the ADSs to decline and existing shareholders may not agree with our financing plans or the terms of such financings. If we raise additional funds through strategic partnerships, collaborations, and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our intellectual property, technologies or our product candidates, or grant licenses on terms unfavorable to us.

Future sales or issuances of the ADSs in the public markets, or the perception of such sales, could depress the trading price of the ADSs.

The sale of a substantial number of shares or ADSs or other equity-related securities in the public markets, or the perception that such sales could occur, could depress the market price of the ADSs and impair our ability to raise capital through the sale of additional equity securities. We may sell large quantities of the ADSs at any time in one or more separate offerings. We cannot predict the effect that future sales of ADSs or other equity-related securities would have on the market price of the ADSs.

11

You are reliant on the Depositary to exercise your voting rights and to receive distributions on ADSs and, as a result, you may be unable to exercise your voting rights on a timely basis or you may not receive certain distributions.

In certain circumstances, holders of ADSs may have limited rights relative to holders of ordinary shares. The rights of holders of ADSs with respect to the voting of ordinary shares and the right to receive certain distributions may be limited in certain respects by the Deposit Agreement among us, The Bank of New York Mellon as depositary and ADS holders from time to time. For example, although ADS holders are entitled under the Deposit Agreement, subject to any applicable provisions of Australian law and of our Constitution, to instruct the depositary as to the exercise of the voting rights pertaining to the ordinary shares represented by the ADSs, and the depositary has agreed that, if we asked it to solicit voting instructions, it will try, as far as practical, to vote the ordinary shares so represented in accordance with such instructions, ADS holders may not receive notices sent by the depositary in time to ensure that the depositary will vote the ordinary shares. This means that, from a practical point of view, the holders of ADSs may not be able to exercise their right to vote. Holders of ADSs in respect of which no timely voting instructions have been received shall be deemed to have instructed the depositary to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by such holders’ ADSs; provided, however, that no such discretionary proxy shall be given with respect to any matter to be voted upon as to which we inform the depositary that (i) we do not wish such proxy to be given, (ii) substantial opposition exists, or (iii) the rights of holders of ordinary shares may be materially and adversely affected. In addition, under the Deposit Agreement, the depositary has the right to restrict distributions to holders of the ADSs in the event that it is unlawful or impractical to make such distributions. We have no obligation to take any action to permit distributions to holders of the ADSs. As a result, holders of ADSs may not receive distributions.

We do not currently intend to pay dividends on our securities and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of the ADSs.

We have not declared or paid any cash dividends on our ordinary shares since November 2012 and do not currently intend to do so for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our operations and growth. Therefore, you are not likely to receive any dividends on your ADSs for the foreseeable future and the success of an investment in the ADSs will depend upon any future appreciation in its value. Consequently, investors may need to sell all or part of their holdings of the ADSs after price appreciation, which may never occur, as the only way to realize any future gains on their investment. There is no guarantee that the ADSs will appreciate in value or even maintain the price at which our shareholders have purchased them. Investors seeking cash dividends should consider not purchasing the ADSs.

12

THE ALUMNI CAPITAL TRANSACTION

On April 19, 2024, we entered into the Purchase Agreement with Alumni Capital. Pursuant to the Purchase Agreement, we may sell to Alumni Capital up to $15,000,000 (the “Investment Amount”), of ADSs (the “Purchase Notice Securities”), from time to time during the term of the Purchase Agreement. The Purchase Agreement contains customary representations, warranties, conditions and indemnification obligations of the parties. Pursuant to the Purchase Agreement, we also agreed to file a registration statement with the SEC, covering the resale of ADSs issued or sold to Alumni Capital under the Purchase Agreement under the Securities Act (the “Registration Statement”).

In consideration for Alumni Capital’s execution and delivery of the Purchase Agreement, we are obligated to issue to Alumni Capital a warrant (the “Warrant”), valid for a term of three (3) years, entitling Alumni Capital to purchase ADSs (the “Warrant ADSs”) with a value (calculated based on the then-current ADS to Ordinary Shares ratio) equal to five percent (5%) of the Investment Amount. The Warrant exercise price is variable and is equal to $6,000,000 divided by the number of outstanding Ordinary Shares as of the time of exercise, multiplied by the then-current ADS to Ordinary Share ratio. Alumni Capital may exercise the Warrant on a cashless basis if we do not maintain an effective registration statement.

We cannot sell any ADSs to Alumni Capital until the date that the Registration Statement is declared effective by the SEC and a final prospectus in connection therewith is filed and all of the other conditions set forth in the Purchase Agreement are satisfied (such date, the “Commencement Date”).

We do not have the right to issue Purchase Notice Securities and Alumni Capital has no obligation to purchase any Purchase Notice Securities if the issuance of the Ordinary Shares underlying such Purchase Notice Securities would result in Alumni Capital and its associates holding more than 19.9% of our outstanding Ordinary Shares (the “Exchange Cap”), unless we obtain shareholder approval to issue ADSs in excess of the Exchange Cap.

Beginning on the Commencement Date and until December 31, 2025, under the terms and subject to the conditions of the Purchase Agreement, from time to time, at our discretion, we have the right, but not the obligation, to issue to Alumni Capital, and Alumni Capital is obligated to purchase, the Purchase Notice Securities, subject to certain limitations set forth in the Purchase Agreement. Specifically, from time to time, from and after the Commencement Date, we may, at our discretion, direct Alumni Capital to purchase the Purchase Notice Securities on any single business day no greater than $500,000 in ADSs ($1,000,000 for the initial purchase thereunder), unless waived upon mutual discretion between us and Alumni Capital, up to an amount no greater than $2,500,000. The purchase price in respect of any purchase notice shall equal the lowest closing price of the ADSs during the five business days prior to the closing of any purchase thereunder, multiplied by 95% (90% for the initial purchase pursuant to the Purchase Agreement).

The Purchase Agreement also prohibits us from directing Alumni Capital to purchase any ADSs if those ADSs, when aggregated with all other ADSs then beneficially owned by Alumni Capital and its affiliates, would result in Alumni Capital and its affiliates having beneficial ownership, at any single point in time, of more than 9.99% of the then total outstanding Ordinary Shares.

The Purchase Agreement will automatically terminate on the earlier of (i) December 31, 2025; or (ii) the date that, pursuant to or within the meaning of any Bankruptcy Law (as defined in the Purchase Agreement), we commence a voluntary case or any person commences a proceeding against us, a Bankruptcy Custodian (as defined in the Purchase Agreement) is appointed for us or for all or substantially all of our property or we make a general assignment for the benefit of our creditors. The Purchase Agreement does not include any of the following: (i) limitations on our use of amounts we receive as the purchase price for the ADSs sold to Alumni Capital; (ii) financial or business covenants; (iii) restrictions on future financings (other than restrictions on its ability to enter into other equity line of credit transactions or transactions that are similar thereto); (iv) rights of first refusal; or (v) participation rights or penalties.

13

Issuances of ADSs to Alumni Capital under the Purchase Agreement will not affect the rights or privileges of our existing shareholders, except that the economic and voting interests of each of our existing shareholders will be diluted as a result of any such issuance. Although the number of Ordinary Shares that our existing shareholders own will not decrease, the Ordinary Shares owned by our existing shareholders will represent a smaller percentage of our total outstanding Ordinary Shares after any such issuance of ADSs to Alumni Capital under the Purchase Agreement. There are substantial risks to our shareholders as a result of the sale and issuance of ADSs to Alumni Capital under the Purchase Agreement. See “Risk Factors.”

14

USE OF PROCEEDS

This prospectus relates to the Offered ADSs that may be offered and sold from time to time by Alumni Capital. We will not receive any proceeds from the resale of the Offered ADSs by Alumni Capital.

We may receive up to $15,750,000 in gross proceeds if we issue to Alumni Capital ADSs issuable pursuant to the Purchase Agreement and if the Warrant is exercised for cash. We estimate that the net proceeds to us from the sale of ADSs to Alumni Capital pursuant to the Purchase Agreement would be up to $11,896,583, assuming that we sell the full amount of ADSs that we have the right, but not the obligation, to sell to Alumni Capital under the Purchase Agreement and the Warrant is exercised for cash, and after other estimated fees and expenses. See “Plan of Distribution” elsewhere in this prospectus for more information.

We intend to use the proceeds from the Purchase Agreement, if any, for general corporate purposes, which may include working capital, expenses related to research, clinical development and commercial efforts, and general and administrative expenses. We currently have no binding agreements or commitments to complete any transaction for the possible acquisition of new therapeutic candidates, though we are currently, and likely to continue, exploring possible acquisition candidates.

15

DIVIDEND POLICY

Since our inception, we have not declared or paid any dividends on our shares. We intend to retain any earnings for use in our business and do not currently intend to pay cash dividends on our ordinary shares. Dividends, if any, on our outstanding ordinary shares will be declared by and subject to the discretion of our board of directors, and subject to Australian law.

Any dividend we declare will be paid to the holders of ADSs, subject to the terms of the Deposit Agreement, to the same extent as holders of our ordinary shares, to the extent permitted by applicable law and regulations, less the fees and expenses payable under the Deposit Agreement. Any dividend we declare will be distributed by the depositary bank to the holders of ADSs, subject to the terms of the Deposit Agreement. See “Description of American Depositary Shares” in this prospectus.

DESCRIPTION OF SHARE CAPITAL

General

Kazia is a public corporation registered under the Australian Corporations Act 2001 (Cth) (“Corporations Act”). Our corporate affairs are principally governed by our Constitution, the Corporations Act and Nasdaq Marketplace Rules. Our ADSs trade on the Nasdaq Capital Market.

The Australian law applicable to our Constitution is not significantly different than a U.S. company’s charter documents except we do not have a limit on our authorized share capital and the concept of par value is not recognized under Australian law as further discussed under the section titled “Our Constitution” below.

Subject to restrictions on the issue of securities under our Constitution, the Corporations Act and any other applicable law, we may at any time issue shares and grant options or warrants on any terms, with the rights and restrictions and for the consideration that our board of directors determine.

The rights and restrictions attaching to ordinary shares are derived through a combination of our Constitution, the common law applicable to Australia, the Corporations Act and other applicable law. A general summary of some of the rights and restrictions attaching to our ordinary shares are summarized below. Each ordinary shareholder is entitled to receive notice of, and to be present, vote and speak at, general meetings.

As of October 31, 2024, we had (i) 435,496,534 ordinary shares outstanding and (ii) outstanding options and warrants to purchase an aggregate of 6,343,481 ordinary shares.

Changes to Our Share Capital

As of June 30, 2024, we had (i) 332,850,784 ordinary shares outstanding and (ii) outstanding options and warrants to purchase an aggregate of 10,022,129 ordinary shares.

Since January 1, 2021, the following changes have been made to our ordinary share capital:

18

19

Our Constitution

Our Constitution is similar in nature to the bylaws of a U.S. corporation. It does not provide for or prescribe any specific objectives or purposes of Kazia. Our Constitution is subject to the terms of the Corporations Act. It may be amended or repealed and replaced by special resolution of shareholders, passed by at least 75% of the votes cast by shareholders entitled to vote on the resolution.

Under Australian law, a company has the legal capacity and powers of an individual both within and outside Australia. The material provisions of our Constitution are summarized below. This summary is not intended to be complete nor to constitute a definitive statement of the rights and liabilities of our shareholders, of which this prospectus forms a part.

Interested Directors

Subject to the Corporations Act, neither a director nor that director’s alternate may vote in respect of any contract or arrangement in which the director has, directly or indirectly, any material interest according to our Constitution. However, that director may execute or otherwise act in respect of that contract or arrangement notwithstanding any material personal interest. Unless a relevant exception applies, the Corporations Act requires our directors to provide disclosure of any material personal interest, and prohibits directors from voting on

20

matters in which they have a material personal interest or being present while such matter is being considered at the board meeting. In addition, the Corporations Act requires shareholder approval of any provision of related party benefits to our directors.

Directors’ Compensation

Our directors are paid remuneration for their services as directors (but excluding any remuneration payable to a director under any executive services contract with us or one of our related bodies corporate) which is determined in a general meeting of shareholders. The aggregate, fixed sum for directors’ remuneration is to be divided among the directors in such proportion as the directors themselves agree and in accordance with our Constitution. The fixed sum remuneration for directors may not be increased except at a general meeting of shareholders and the particulars of the proposed increase are required to have been provided to shareholders in the notice convening the meeting. In addition, executive directors may be paid remuneration as determined by the directors from time to time and, including as a salary, commission or participation in profits and/or by the issue of shares, options to acquire shares or performance rights or other incentives (or a combination of any of these methods of remuneration).

Fees payable to our non-executive directors must be by way of a fixed sum and not by way of a commission on or a percentage of profits. Remuneration paid to our executive directors must also not include a commission or percentage of operating revenue.

Pursuant to our Constitution, if, at our board’s request, any director performs extra services or makes special exertions, Kazia may remunerate that director by paying for those services and exertions.

In addition to other remuneration provided in our Constitution, all of our directors are entitled to be paid by us for all other travelling, accommodation and other expenses incurred by the directors in attending and returning from general meetings, board meetings, committee meetings or otherwise in connection with our business.

Borrowing Powers Exercisable by Directors

Pursuant to our Constitution, the management and control of our business affairs are vested in our board of directors. Our board of directors has the power to raise or borrow money or obtain other financial accommodation for Company purposes, and may grant security for the repayment of that sum or sums or the payment, performance or fulfilment of any debts, liabilities, contracts or obligations incurred or undertaken by the Company in any manner and on any terms and conditions as our board thinks fit.

Retirement of Directors

Pursuant to our Constitution, at least one director, other than the Managing Director, must retire from office at every annual general meeting unless there has been an election of directors earlier that year. A director, other than the director who is the Managing Director, must retire from office at the conclusion of three years or following the third annual general meeting after which the director was elected, whichever is longer. If no director is required to retire at an annual general meeting, then the director to retire will be the director who has been longest in office since last being elected. Retired directors are eligible for a re-election to the board of directors unless disqualified from acting as a director under the Corporations Act or our Constitution.

Rights and Restrictions on Classes of Shares

The rights attaching to our ordinary shares are detailed in our Constitution. Our Constitution provides that our directors may issue shares with any preferential, deferred or special rights, privileges or conditions or with any restriction (whether in relation to dividends, voting, return of share capital or otherwise) as our board of directors may determine. Subject to any approval which is required from our shareholders under the Corporations Act, we may issue further shares on such terms and conditions as our board of directors resolves.

21

Dividend Rights

Our board of directors may from time to time determine to pay and declare dividends to shareholders. All dividends unclaimed for one year after having been declared may be invested or otherwise made use of by our board of directors for our benefit until claimed or otherwise disposed of in accordance with our Constitution.

Voting Rights

Under our Constitution, the rights and restrictions attaching to a class of shares, each shareholder has one vote on a show of hands at a meeting of the shareholders unless a poll is demanded under the Constitution or the Corporations Act. On a poll vote, each shareholder shall have one vote for each fully paid share and a fractional vote for each share held by that shareholder that is not fully paid, such fraction being equivalent to the proportion of the amount that has been paid to such date on that share. Shareholders may vote in person or by proxy, attorney or representative. Under Australian law, shareholders of a public company are generally not permitted to approve corporate matters by written consent. Our Constitution does not provide for cumulative voting. Note that ADS holders may not directly vote at a meeting of the shareholders but may instruct the depositary to vote the number of deposited ordinary shares their ADSs represent.

Right to Share in Our Profits

Pursuant to our Constitution, our shareholders are entitled to participate in our profits only by payment of dividends. Our board of directors may from time to time determine to pay dividends to the shareholders; however, no dividend is payable except in accordance with the thresholds set out in the Corporations Act.

Rights to Share in the Surplus in the Event of Winding Up

Our Constitution provides for the right of shareholders to participate in a surplus in the event of our winding up, subject to the rights attaching to a class of shares, the Constitution and the Corporations Act.

No Redemption Provision for Ordinary Shares

There are no redemption provisions in our Constitution in relation to ordinary shares. Under our Constitution, any preference shares may be issued on the terms that they are, or may at the option of Kazia or the holder be, liable to be redeemed or converted into ordinary shares.

Variation or Cancellation of Share Rights

Subject to the Corporations Act and the terms of issue of shares of that class, the rights attached to shares in a class of shares may only be varied or cancelled by either:

Directors May Make Calls

Our Constitution provides that our directors may make calls on a shareholder for all monies unpaid on shares held by that shareholder, other than monies payable at fixed times under the conditions of allotment.

General Meetings of Shareholders

General meetings of shareholders may be called by our board of directors. Except as permitted under the Corporations Act, shareholders may not convene a meeting. The Corporations Act requires the directors to call

22

and arrange to hold a general meeting on the request of shareholders with at least 5% of the votes that may be cast at a general meeting. Notice of the proposed meeting of our shareholders is required at least 28 days prior to such meeting under the Corporations Act.

Foreign Ownership Regulation

Our Constitution does not impose specific limitations on the rights of non-residents to own securities. However, acquisitions and proposed acquisitions of securities in Australian companies may be subject to review and approval by the Australian Federal Treasurer under the Foreign Acquisitions and Takeovers Act 1975 (Cth), or the Foreign Takeovers Act, which generally applies to acquisitions or proposed acquisitions:

However, in general terms, no such review or approval under the Foreign Takeovers Act is required if the foreign acquirer is a U.S. entity or an entity from certain other countries and the value of the target is less than A$1,250 million, unless the company operates in certain sensitive industries. Exemptions do not apply to investments by foreign governments and their associated entities.

The Australian Federal Treasurer may prevent a proposed acquisition in the above categories or impose conditions on such acquisition if the Treasurer is satisfied that the acquisition would be contrary to the national interest. If a foreign person acquires shares or an interest in shares in an Australian company in contravention of the Foreign Takeovers Act, the Australian Federal Treasurer may make a range of orders including an order the divestiture of such person’s shares or interest in shares in that Australian company.

Ownership Threshold

There are no specific provisions in our Constitution that require a shareholder to disclose ownership above a certain threshold. The Corporations Act, however, requires a shareholder to notify us once it, together with its associates, acquires a 5% interest in our ordinary shares, at which point the shareholder will be considered to be a “substantial” shareholder. Further, once a shareholder owns (alone or together with associates) a 5% interest in us, such shareholder must notify us of any increase or decrease of 1% or more in its holding of our ordinary shares, and must also notify us on its ceasing to be a “substantial” shareholder. As we are also a U.S. public company, our shareholders are also subject to disclosure requirements under U.S. securities laws.

Issues of Shares and Change in Capital

Subject to our Constitution, the Corporations Act, and any other applicable law, we may at any time issue shares and give any person a call or option over any shares on any terms, with preferential, deferred or special rights, privileges or conditions or with any restrictions and for the consideration and other terms that the directors determine.

Subject to the requirements of our Constitution, the Corporations Act and any other applicable law, including relevant shareholder approvals, we may consolidate or divide our share capital into a larger or smaller number by resolution, reduce our share capital in any manner (provided that the reduction is fair and reasonable to our shareholders as a whole, does not materially prejudice our ability to pay creditors and obtains the necessary shareholder approval) or buy back our ordinary shares whether under an equal access buy-back or on a selective basis.

23

Change of Control

Takeovers of listed Australian public companies, such as Kazia, are regulated by the Corporations Act, which prohibits the acquisition of a “relevant interest” in issued voting shares in a listed company if the acquisition will lead to that person’s or someone else’s “voting power” (being the person’s relevant interests plus those of its associates) in Kazia’s issued shares increasing from 20% or below to more than 20% or increasing from a starting point that is above 20% and below 90% (“Takeovers Prohibition”), subject to a range of exceptions.

Generally, a person will have a relevant interest in securities if the person:

If, at a particular time:

then the other person is taken to already have a relevant interest in the securities.

There are a number of exceptions to the Takeovers Prohibition on acquiring a relevant interest in issued voting shares above 20%. In general terms, some of the more significant exceptions include:

24

Breaches of the takeovers provisions of the Corporations Act are criminal offenses. The Australian Securities and Investments Commission, or ASIC, and the Australian Takeover Panel have a wide range of powers relating to breaches of takeover provisions or other circumstances deemed to be unacceptable (whether or not they involve a breach of the takeover provisions), including the ability to make orders canceling contracts, freezing transfers of, and rights attached to, securities, and forcing a party to dispose of securities. There are certain defenses to breaches of the takeover provisions provided in the Corporations Act.

Access to and Inspection of Documents

Inspection of our records is governed by the Corporations Act. Any member of the public has the right to inspect or obtain copies of our registers on the payment of a prescribed fee. Shareholders are not required to pay a fee for inspection of our registers or minute books of the meetings of shareholders. Other corporate records, including minutes of directors’ meetings, financial records and other documents, are not open for inspection by shareholders. Where a shareholder is acting in good faith and an inspection is deemed to be made for a proper purpose, a shareholder may apply to the court to make an order for inspection of our books.

25

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

The Bank of New York Mellon, as depositary, has registered and delivered American Depositary Shares, also referred to as ADSs. Each ADS represents 100 ordinary shares (or a right to receive 100 ordinary shares) deposited with HSBC Bank Australia Limited, as custodian for the depositary. Each ADS may also represent any other securities, cash or other property which may be held by the depositary. The depositary’s office at which the ADSs are administered is located at 101 Barclay Street, New York, New York 10286. The Bank of New York Mellon’s principal executive office is located at 240 Greenwich Street, New York, New York 10286.

You may hold ADSs either:

If you hold ADSs directly, you are a registered ADS holder, or ADS holder. This description assumes you are an ADS holder. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

The Direct Registration System, or DRS, is a system administered by The Depository Trust Company, also referred to as DTC, pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership is confirmed by periodic statements sent by the depositary to the registered holders of uncertificated ADSs.

As an ADS holder, we will not treat you as one of our shareholders and you will not have shareholder rights. Australian law governs shareholder rights. The depositary is the holder of the shares underlying your ADSs. As a registered holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary and you, as an ADS holder, and all other persons directly or indirectly holding ADSs sets out ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs.

The following is a summary of the material provisions of the deposit agreement. Because it is a summary, it does not contain all the information that may be important to you. For more complete information, you should read the entire deposit agreement and the form of ADR which summarizes certain terms of your ADSs. A copy of the deposit agreement is filed as an exhibit to the registration statement of which this prospectus forms a part. You may also obtain a copy of the deposit agreement at the SEC’s Public Reference Room which is located at 100 F Street, NE, Washington, DC 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. You may also find the registration statement and the deposit agreement on the SEC’s website at http://www.sec.gov.

Dividends and Other Distributions

How will you receive dividends and other distributions on the shares?

The depositary has agreed to pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent.

26

Before making a distribution, any withholding taxes, or other governmental charges that must be paid will be deducted. It will distribute only whole U.S. dollars and cents and will round fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the distribution.

If the depositary makes rights available to ADS holders, it will exercise the rights and purchase the shares on your behalf all in accordance with your instructions. The depositary will then deposit the shares and deliver ADSs to you. It will only exercise rights if you pay the exercise price and any other charges the rights require you to pay and comply with other applicable instructions.

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. We have no obligation to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of ADSs, shares, rights or any other property to ADS holders. This means that you may not receive the distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you.

Deposit, Withdrawal and Cancellation

How are ADSs issued?

The depositary will deliver ADSs if you or your broker deposit shares or evidence of rights to receive shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or share transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons that made the deposit.

27

How can ADS holders withdraw the deposited securities?

You may surrender your ADSs at the depositary’s office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or share transfer taxes or fees, the depositary will deliver the shares and any other deposited securities underlying the ADSs to the ADS holder or a person designated by you at the office of the custodian. In the alternative, at your request, risk and expense, the depositary will deliver the deposited securities at its office, if feasible.

How do ADS holders interchange between certificated ADSs and uncertificated ADSs?

You may surrender your ADR to the depositary for the purpose of exchanging your ADR for uncertificated ADSs. The depositary will cancel that ADR and will send to you a statement confirming that you are the registered holder of uncertificated ADSs. Alternatively, upon receipt by the depositary of a proper instruction from a registered holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary will execute and deliver to you an ADR evidencing those ADSs.

Voting Rights

How do you vote?

You may instruct the depositary to vote the number of deposited ordinary shares your ADSs represent. The depositary will notify you of shareholders’ meetings and arrange to deliver our voting materials to you upon our request. Those materials will describe the matters to be voted on and explain how ADS holders may instruct the depositary how to vote. For instructions to be valid, they must reach the depositary by a date established by the depositary.

Otherwise, you will not be able to exercise your right to vote unless you withdraw the shares underlying the ADSs. However, you may not know about the meeting with a sufficient amount of advance notice to withdraw the shares.

The depositary will attempt, as far as practical, subject to the laws of Australia and of our Constitution or similar documents, to vote or to have its agents vote the shares or other deposited securities represented by your ADSs as instructed by ADS holders. The depositary will only vote or attempt to vote as instructed.

We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your ordinary shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote and there may be nothing you can do if your ordinary shares are not voted as you requested.

In order to give you a reasonable opportunity to instruct the depositary as to the exercise of voting rights relating to deposited securities, if we request the depositary to act, we agree to give the depositary notice of any such meeting and details concerning the matters to be voted upon at least 45 days in advance of the meeting date.

Fees and Expenses

28

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid. The depositary may collect any of its fees by deduction from any cash distribution payable to you.

From time to time, the depositary may make payments to us to reimburse or share revenue from the fees collected from you, or waive fees and expenses for services provided, generally relating to costs and expenses arising out of establishment and maintenance of the ADS program. In performing its duties under the deposit agreement, the depositary may use brokers, dealers or other service providers that are affiliates of the depositary and that may earn or share fees or commissions.

Payment of Taxes

You will be responsible for any taxes or other governmental charges payable on your ADSs or on the deposited securities represented by any of your ADSs. The depositary may refuse to register any transfer of your ADSs or allow you to withdraw the deposited securities represented by your ADSs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to you any proceeds, or send to ADS holders any property, remaining after it has paid the taxes.

29

Reclassifications, Recapitalizations and Mergers

Amendment and Termination

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the ADRs without your consent for any reason. If an amendment adds or increases fees or charges, except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items, or prejudices a substantial right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended.

How may the deposit agreement be terminated?

The depositary may initiate termination of the deposit agreement if at any time 60 days shall have expired after the depositary delivered to us a written resignation notice and a successor depositary has not been appointed and accepted its appointment, an insolvency event or delisting event occurs, or a termination option event has occurred or will occur. If termination of the deposit agreement is initiated, the depositary shall deliver a notice of termination to you setting a date for termination, which shall be at least 90 days after the date of that notice, and the deposit agreement shall terminate on that date. After termination, the depositary and its agents will do the following under the deposit agreement (but nothing else):

At any time after termination, the depositary may sell any remaining deposited securities. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement for the pro rata benefit of the ADS holders that have not surrendered their ADSs. It will not invest the money and has no liability for interest. The depositary’s only obligations will be to indemnify the relevant persons under the deposit agreement and to account for the money and other cash. After termination our only obligations will be to indemnify the depositary and to pay fees and expenses of the depositary that we agreed to pay.

30

Limitations on Obligations and Liability

Limits on our Obligations and the Obligations of the Depositary; Limits on Liability to Holders of ADSs

The deposit agreement expressly limits our obligations and the obligations of the depositary. It also limits our liability and the liability of the depositary. We and the depositary:

In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

Requirements for Depositary Actions

Before the depositary will deliver or register a transfer of an ADS, make a distribution on an ADS, or permit withdrawal of shares, the depositary may require:

The depositary may refuse to deliver ADSs or register transfers of ADSs generally when the transfer books of the depositary or our transfer books are closed or at any time if the depositary or we think it advisable to do so.

Your Right to Receive the Shares Underlying your ADSs

You have the right to cancel your ADSs and withdraw the underlying shares at any time except:

This right of withdrawal may not be limited by any other provision of the deposit agreement.

31

Direct Registration System

In the deposit agreement, all parties to the deposit agreement acknowledge that the DRS and Profile Modification System, or Profile, will apply to uncertificated ADSs upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC under which the depositary may register the ownership of uncertificated ADSs, which ownership may be evidenced by periodic statements sent by the depositary to the registered holders of uncertificated ADSs. Profile is a required feature of DRS that allows a DTC participant, claiming to act on behalf of a registered holder of ADSs, to direct the depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs to the DTC account of that DTC participant without receipt by the depositary of prior authorization from the ADS holder to register that transfer.

In connection with and in accordance with the arrangements and procedures relating to DRS/Profile, the parties to the deposit agreement understand that the depositary will not determine whether the DTC participant that is claiming to be acting on behalf of an ADS holder in requesting registration of transfer and delivery described in the paragraph above has the actual authority to act on behalf of the ADS holder (notwithstanding any requirements under the Uniform Commercial Code). In the deposit agreement, the parties agree that the depositary’s reliance on and compliance with instructions received by the depositary through the DRS/Profile System and in accordance with the deposit agreement will not constitute negligence or bad faith on the part of the depositary.

Shareholder Communications; Inspection of Register of Holders of ADSs

The depositary will make available for your inspection at its office all communications that it receives from us as a holder of deposited securities that we make generally available to holders of deposited securities. The depositary will send you copies of those communications if we ask it to. You have a right to inspect the register of holders of ADSs, but not for the purpose of contacting those holders about a matter unrelated to our business or the ADSs.

Disclosure of Interests

We may from time to time request ADS holders to provide information as to the capacity in they own or owned ADSs and regarding the identity of any other persons then or previously interested in such ADSs and the nature of such interest. Each ADS holder agrees to provide any information of that kind that is requested by us or the depositary. To the extent that provisions of or governing the deposited securities or the rules or regulations of any governmental authority or securities exchange or automated quotation system may require the disclosure of beneficial or other ownership of deposited securities, other shares and other securities to us or other persons and may provide for blocking transfer and voting or other rights to enforce such disclosure or limit such ownership, the depositary has agreed to use its reasonable efforts to comply with our written instructions in respect of any such enforcement or limitation.

32

SELLING SHAREHOLDER

This prospectus relates to the possible resale from time to time by Alumni Capital of any or all of the ADSs that may be issued by us to Alumni Capital under the Purchase Agreement. For additional information regarding the issuance of ADSs covered by this prospectus, see the section titled “Alumni Capital Transaction” above. We are registering the ADSs pursuant to the provisions of the Purchase Agreement in order to permit the Selling Shareholder to offer the ADSs for resale from time to time. Except for the transactions contemplated by the Purchase Agreement, Alumni Capital has not had any material relationship with us within the past three years. As used in this prospectus, the term “Selling Shareholder” means Alumni Capital.

The table below presents information regarding the Selling Shareholder and the ADSs that it may offer from time to time under this prospectus. This table is prepared based on information supplied to us by the Selling Shareholder, and reflects holdings as of May 13, 2024, which has been adjusted to give effect to the ADS Ratio Change. The number of shares in the column “Maximum Number of ADSs to be Offered Pursuant to this Prospectus” represents all of the ADSs that the Selling Shareholder may offer under this prospectus. The Selling Shareholder may sell some, all or none of its ADSs in this offering. The Selling stockholder may have sold or transferred some or all of the ADSs indicated below and may in the future sell or transfer some or all of the ADSs indicated below in transactions exempt from the registration requirements of the Securities Act rather than under this prospectus. We do not know how long the Selling Shareholder will hold the ADSs before selling them, and we currently have no agreements, arrangements or understandings with the Selling Shareholder regarding the sale of any of the ADSs.

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act, and includes Ordinary Shares with respect to which the Selling Shareholder has voting and investment power. The percentage of ADSs beneficially owned by the Selling Shareholder prior to the offering shown in the table below is based on an aggregate of 435,496,534 Ordinary Shares outstanding on October 31, 2024. Because the purchase price of the ADSs issuable under the Purchase Agreement is determined on each purchase date, the number of ADSs that may actually be sold by us under the Purchase Agreement may be fewer than the number of ADSs being offered by this prospectus. The fourth column assumes the sale of all of the ADSs offered by the Selling Shareholder pursuant to this prospectus.

33

MATERIAL TAX CONSIDERATIONS

U.S. Taxation

This section describes certain material U.S. federal income tax consequences to a U.S. holder (as defined below) of owning Ordinary Shares or ADSs. It applies only to Ordinary Shares or ADSs that are held as capital assets for tax purposes. This section does not apply to a holder of Ordinary Shares or ADSs that is a member of a class of holders subject to special rules, including a financial institution, a dealer or trader in securities, a regulated investment company, a real estate investment trust, a grantor trust, a U.S. expatriate, a tax-exempt organization, an insurance company, a person liable for alternative minimum tax, a person who actually or constructively owns 10% or more of the stock of the Company, a person that holds Ordinary Shares or ADSs as part of a straddle or a hedging or conversion transaction, a person that purchases or sells Ordinary Shares or ADSs as part of a wash sale for tax purposes, or a person whose functional currency is not the U.S. dollar. Further, this description does not address state, local, non-U.S, or other tax laws, nor does it address the 3.8% U.S. federal Medicare tax on net investment income, the alternative minimum tax or the U.S. federal gift and estate tax consequences of owning and disposing of Ordinary Shares or ADSs.

For purposes of this description, a “U.S. holder” is a beneficial owner of Ordinary Shares or ADSs who holds such Ordinary Shares or ADSs as capital assets within the meaning of the Code and is, for U.S. federal income tax purposes: (i) an individual citizen or resident of the United States; (ii) a corporation created or organized in or under the laws of the United States or any state thereof, including the District of Columbia; (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust that either (a) is subject to the supervision of a court within the United States and has one or more U.S. persons with authority to control all substantial decisions or (b) has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

If a partnership holds the Ordinary Shares or ADSs, the U.S. federal income tax treatment of a partner generally will depend on the status of the partner and the tax treatment of the partnership. A partner in a partnership holding the Ordinary Shares or ADSs should consult its tax advisor with regard to the U.S. federal income tax treatment of an investment in the Ordinary Shares or ADSs.

The discussion is based on the Code, administrative pronouncements, judicial decisions, and final, temporary and proposed Treasury Regulations, all as of the date hereof, changes to any of which may affect the tax consequences described herein—possibly with retroactive effect. There can be no assurances that the Internal Revenue Service (the “IRS”) will not take a contrary or different position concerning the tax consequences of the ownership and disposition of our Ordinary Shares or ADSs or that such a position would not be sustained by a court. We have not obtained, nor do we intend to obtain, a ruling with respect to the U.S. federal income tax considerations relating to the purchase, ownership or disposition of our Ordinary Shares or ADSs. Holders should consult their tax advisers concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our Ordinary Shares or ADSs in their particular circumstances.

This section is in part based on the representations of the Depositary and the assumption that each obligation in the deposit agreement and any related agreement will be performed in accordance with its terms.

Exchange of ADSs for Ordinary Shares

In general, for U.S. federal income tax purposes, a holder of ADSs will be treated as the owner of the Ordinary Shares represented by those ADSs. Exchanges of Ordinary Shares for ADSs, and ADSs for Ordinary Shares generally will not be subject to U.S. federal income tax.

Distributions

Subject to the Passive Foreign Investment Company (“PFIC”) rules discussed below, U.S. holders generally will include as dividend income the U.S. dollar value of the gross amount of any distributions of cash or property

34

(without deduction for any withholding tax), other than certain pro rata distributions of Ordinary Shares, with respect to Ordinary Shares or ADSs to the extent the distributions are made from our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. A U.S. holder will include the dividend income on the day actually or constructively received (i) by the holder, in the case of Ordinary Shares, or (ii) by the depositary, in the case of ADSs. We do not intend to maintain calculations of earnings and profits, as determined for U.S. federal income tax purposes. Consequently, any distributions generally will be treated as dividend income.

Dividends paid to a non-corporate U.S. holder on shares or ADSs will generally be taxable at the preferential rates applicable to long-term capital gains provided (a) that certain holding period requirements are satisfied, (b) (i) the U.S.-Australia income tax treaty (“the Treaty”) is a qualified treaty and we are eligible for benefits under the Treaty or (ii) our Ordinary Shares or ADSs are readily tradable on a U.S. securities market, and (c) provided that we were not, in the taxable year prior to the year in which the dividend was paid, and are not, in the taxable year in which the dividend is paid, a PFIC. The Treaty has been approved for the purposes of the qualified dividend rules and the ADSs are listed on Nasdaq. If the Company is a PFIC, any dividends paid to a noncorporate U.S. holder will not qualify for the preferential tax rates ordinarily applicable to “qualified dividends.” In the case of a corporate U.S. holder, dividends on shares and ADSs are taxed as ordinary income and will not be eligible for the dividends received deduction generally allowed to U.S. corporations in respect of dividends received from other U.S. corporations.

The amount of any cash distribution paid in any foreign currency will be equal to the U.S. dollar value of such currency, calculated by reference to the spot rate in effect on the date such distribution is received by the U.S. holder or, in the case of ADSs, by the Depositary, regardless of whether and when the foreign currency is in fact converted into U.S. dollars. If the foreign currency is converted into U.S. dollars on the date received, the U.S. holder generally should not recognize foreign currency gain or loss on such conversion. If the foreign currency is not converted into U.S. dollars on the date received, the U.S. holder will have a basis in the foreign currency equal to its U.S. dollar value on the date received, and generally will recognize foreign currency gain or loss on a subsequent conversion or other disposal of such currency. Such foreign currency gain or loss generally will be treated as U.S. source ordinary income or loss for foreign tax credit limitation purposes.

Dividends will be income from sources outside the United States, and generally will be “passive category” income or, for certain taxpayers, “general category” income, which are treated separately from each other for the purpose of computing the foreign tax credit allowable to a U.S. holder. The availability of the foreign tax credit and the application of the limitations on its availability are fact specific and are subject to complex rules. In general, a taxpayer’s ability to use foreign tax credits may be limited and is dependent on the particular circumstances. U.S. holders should consult their own tax advisors with respect to these matters.

Sale, Exchange or other Disposition of Ordinary Shares or ADSs

Subject to the PFIC rules discussed below, a U.S. holder who sells or otherwise disposes of Ordinary Shares or ADSs will recognize a capital gain or loss for U.S. federal income tax purposes equal to the difference between the U.S. dollar value of the amount realized and the holder’s tax basis, determined in U.S. dollars, in those Ordinary Shares or ADSs. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. The capital gain of a non-corporate U.S. holder is generally taxed at preferential rates where the holder has a holding period greater than 12 months in the shares or ADSs sold. There are limitations on the deductibility of capital losses.

The U.S. dollar value of any foreign currency received upon a sale or other disposition of Ordinary Shares or ADSs will be calculated by reference to the spot rate in effect on the date of sale or other disposal (or, in the case of a cash basis or electing accrual basis taxpayer, at the spot rate of exchange on the settlement date). A U.S. holder will have a tax basis in the foreign currency received equal to that U.S. dollar amount, and generally will recognize foreign currency gain or loss on a subsequent conversion or other disposal of the foreign currency.

35

This foreign currency gain or loss generally will be treated as U.S. source ordinary income or loss for foreign tax credit limitation purposes. If such foreign currency is converted into U.S. dollars on the date received by the U.S. holder, a cash basis or electing accrual basis U.S. holder should not recognize any gain or loss on such conversion.

Passive Foreign Investment Company

A non-U.S. corporation will be a PFIC for U.S. federal income tax purposes for any taxable year if either:

Passive income does not include rents and royalties derived from the active conduct of a trade or business. If the stock of a non-U.S. corporation is publicly traded for the taxable year, the asset test is applied using the fair market value of the assets for purposes of measuring such corporation’s assets. If we own at least 25% (by value) of the stock of another corporation, we will be treated, for purposes of the PFIC tests, as owning our proportionate share of the other corporation’s assets and receiving our proportionate share of the other corporation’s income for purposes of the PFIC income and asset tests. If the stock of a non-U.S. corporation is publicly-traded for the taxable year, the asset test is applied using the fair market value of the assets for purposes of measuring such corporation’s assets. If we were a PFIC in any year during a U.S. holder’s holding period for our Ordinary Shares or ADSs, we would ordinarily continue to be treated as a PFIC for each subsequent year during which the U.S. holder owned the Ordinary Shares or ADSs, regardless of whether we continue to meet the tests described above unless (a) we ceased to be a PFIC and (b) the U.S. holder has made a deemed sale election under the PFIC rules which may result in recognition of gain (but not loss), taxable under the PFIC rules described below, without the receipt of any corresponding cash. Based on the composition of our assets and income in the 2023 taxable year, we believe that we were a PFIC for U.S. federal income tax purposes with respect to our 2023 taxable year. However, the determination of PFIC status is a fact-intensive determination that must be made annually at the close of each taxable year applying principles and methodologies that in some circumstances are unclear and subject to varying interpretation. As a result, there can be no assurance that we will be treated as a PFIC for the 2023 taxable year, the 2024 taxable year, current taxable year or any future taxable year. Based on the composition of our assets and income in the 2024 taxable year, if we will not be treated as a PFIC in the 2023 taxable year, we believe that we were not a PFIC for U.S. federal income tax purposes with respect to our 2024 taxable year. However, as stated above, the determination of PFIC status is a fact-intensive determination that must be made annually at the close of each taxable year applying principles and methodologies that in some circumstances are unclear and subject to varying interpretation. As a result, even if we will not be a treated as a PFIC in the 2023 taxable year, there can be no assurance that we will not be treated as a PFIC in the 2024 taxable year, the current year or for any future taxable year. Changes in the nature of our income or assets or a decrease in the trading price of our Ordinary Shares or ADSs may impact the determination of our PFIC status.

If we are a PFIC, and you are a U.S. holder, then unless you make one of the elections described below, a special tax regime will apply to both (a) any “excess distribution” by us to you (generally, your ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by you in the shorter of the three preceding years or your holding period for our Ordinary Shares) and (b) any gain realized on the sale or other disposition of the Ordinary Shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over your holding period, (b) the amount deemed realized in each year had been subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the

36

current period or any taxable period before we became a PFIC, which would be subject to tax at the U.S. holder’s regular ordinary income rate for the current year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long-term capital gains discussed above under “Distributions.”

Certain elections may potentially be used to reduce the adverse impact of the PFIC rules on U.S. holders (“qualifying electing fund”, or QEF) , and “mark-to-market” elections), but these elections may accelerate the recognition of taxable income and may result in the recognition of ordinary income.

The rules described above for excess distributions would not apply to a U.S. holder if the U.S. holder makes a timely QEF election for the first taxable year of the U.S. holding period for Ordinary Shares and we comply with specified reporting requirements. A timely QEF election for a taxable year generally must be made on or before the due date (as may be extended) for filing the taxpayer’s U.S. federal income tax return for the year. A U.S. holder who makes a QEF election generally must report on a current year basis a pro rata share of our ordinary earnings and net capital gain for any taxable year in which we are a PFIC, whether or not those earnings or gains are distributed. A U.S. holder who makes a QEF election must file a Form 8621 with its annual income tax return. We intend to make available an information statement that will contain the necessary information required for a U.S. holder to make a QEF election with respect to our ordinary shares. We may choose to provide such information on our website.

If a U.S. holder does not make a QEF election for the first taxable year of the U.S. holder’s holding period for Ordinary Shares during which we are a PFIC, the QEF election will not be treated as timely and the adverse tax regime described above would apply to dispositions of or excess distributions on the ordinary shares. In such case, a U.S. holder may make a deemed sale election whereby the U.S. holder would be treated as if the U.S. holder had sold the Ordinary Shares in a fully taxable sale at fair market value on the first day of such taxable year in which the QEF election takes effect. Such U.S. holder would be required to recognize any gain on the deemed sale as an excess distribution and pay any tax and interest due on the excess distribution when making the deemed sale election. The effect of such further election would be to restart the U.S. holder’s holding period in the Ordinary Shares, subject to the QEF regime, and to purge the PFIC status of such Ordinary Shares going forward.

If a U.S. holder makes the mark-to-market election with respect to Ordinary Shares, the U.S. holder generally will recognize as ordinary income any excess of the fair market value of the Ordinary Shares at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss in respect of any excess of the adjusted tax basis of the Ordinary Shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). If a U.S. holder makes the election, the U.S. holder’s tax basis in the Ordinary Shares will be adjusted to reflect these income or loss amounts. Any gain recognized on the sale or other disposition of Ordinary Shares in a year when we are a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of income previously included as a result of the mark-to-market election). The mark-to-market election is available only if we are a PFIC and our Ordinary Shares are “regularly traded” on a “qualified exchange”. Our Ordinary Shares will be treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the Ordinary Shares are traded on a qualified exchange on at least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principle purposes the meeting of the trading requirement as disregarded). The Nasdaq is a qualified exchange for this purpose and consequently, if the Ordinary Shares are regularly traded, the mark-to-market election should be available to a U.S. holder.

U.S. holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the consequences of the alternative treatments would be in their particular circumstances.

37

If we are a PFIC, the general tax treatment for U.S. holders described in this section would apply to indirect distributions and gains deemed to be realized by U.S. holders in respect of any of our subsidiaries that also may be determined to be PFICs.

If a U.S. holder owns Ordinary Shares during any year in which we are a PFIC and the U.S. holder recognizes gain on a disposition of our Ordinary Shares or receives distributions with respect to our ordinary shares, the U.S. holder generally will be required to file an IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund) with respect to the company, generally with the U.S. holder’s federal income tax return for that year. If our company were a PFIC for a given taxable year, then you should consult your tax advisor concerning your annual filing requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. investors are urged to consult their tax advisers with respect to the ownership and disposition of our Ordinary Shares or ADSs, the consequences to them of an investment in a PFIC, any elections available with respect to our Ordinary Shares and the IRS information reporting obligations with respect to the ownership and disposition of our Ordinary Shares or ADSs.

U.S. Information Reporting and Back-up Withholding

Dividend payments with respect to our Ordinary Shares or ADSs and proceeds from the sale or other disposition of our Ordinary Shares or ADSs may be subject to information reporting to the IRS and possible U.S. backup withholding. Back-up withholding will not apply, however, to a U.S. holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from back- up withholding. U.S. holders who are required to establish their exempt status may be required to provide such certification on Internal Revenue Service (“IRS”) Form W-9. U.S. holders should consult their tax advisors regarding the application of the U.S. information reporting and back-up withholding rules.

Back-up withholding is not an additional tax. Amounts withheld as back-up withholding may be credited against a U.S. holder’s U.S. federal income tax liability, and such holder may obtain a refund of any excess amounts withheld under the back-up withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Information With Respect to Foreign Financial Assets

Certain U.S. holders that own “specified foreign financial assets” with an aggregate value in excess of $50,000 are generally required to file an information statement along with their U.S. federal tax returns, currently on IRS Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. If a U.S. holder does not include in such holder’s gross income an amount relating to one or more specified foreign financial assets, and the amount such U.S. holder omits is more than $5,000, any tax such U.S. holder owes for the tax year can be assessed at any time within 6 years after the filing of such U.S. holder’s federal tax return. U.S. holders who fail to report the required information could be subject to substantial penalties. U.S. holders are encouraged to consult with their own tax advisors regarding the possible application of the foregoing to our Ordinary Shares or ADSs in light of their particular circumstances.

Australian Tax Considerations

In this section, we discuss the material Australian income tax, stamp duty and goods and services tax considerations related to the acquisition, ownership and disposal by the absolute beneficial owners of the Ordinary Shares and ADSs.

It is based upon existing Australian tax law as of the date of this registration statement, which is subject to change, possibly retrospectively. This discussion does not address all aspects of Australian tax law which may be

38

important to particular investors in light of their individual investment circumstances, such as shares held by investors subject to special tax rules (for example, financial institutions, insurance companies, superannuation funds, trusts or tax-exempt organizations). In addition, this summary does not discuss any state tax considerations, other than stamp duty.

Prospective investors are urged to consult their tax advisors regarding the tax considerations of the acquisition, ownership and disposition of the shares. Unless otherwise mentioned, this summary is based upon the premise that the holder is a US holder (as defined in the U.S. Taxation section), is not an Australian tax resident, holds their shares on capital account for Australian tax purposes, and is not carrying on business in Australia through a permanent establishment (referred to as a “Non-Australian Investor” in this summary).

Australian Income Tax

Nature of ADSs for Australian Taxation Purposes

Ordinary shares represented by ADSs held by a U.S. holder will be treated for Australian taxation purposes as held under a “bare trust” for such holder. Consequently, the underlying Ordinary Shares will be regarded as owned by the ADS holder for Australian income tax and capital gains tax purposes. Dividends paid on the underlying Ordinary Shares will also be treated as dividends paid to the ADS holder, as the person beneficially entitled to those dividends. Therefore, in the following analysis we discuss the tax consequences to Non-Australian Investors which, for Australian taxation purposes, will be the same as to U.S. holders of ADSs.

Taxation of Dividends

Australia operates a dividend imputation system under which dividends may be declared to be “franked” to the extent of tax paid on company profits. Fully franked dividends are not subject to dividend withholding tax. Dividends payable to Non-Australian Investors will be subject to dividend withholding tax, to the extent the dividends are not declared to be conduit foreign income, or CFI, and are unfranked. Dividend withholding tax will be imposed at 30%, unless a shareholder is a resident of a country with which Australia has a double taxation agreement and qualifies for the benefits of the treaty. In accordance with the provisions of the Double Taxation Convention between Australia and the United States, the maximum rate of Australian withholding tax on any unfranked portion of a dividend to which a tax resident of the United States is beneficially entitled may be reduced to 15%, with a potential further reduction to 5% where the U.S. resident beneficially entitled to the dividends is a company which holds directly 10% or more of the voting power in our company. To rely on the Double Taxation Convention a U.S. tax resident must also be a “qualified person” within the meaning of the Double Taxation Convention. Shareholders seeking to rely on the Double Taxation Convention should obtain specialist taxation advice.

Tax on Sales or other Dispositions of Shares or ADSs—Capital Gains Tax

Non-Australian Investors may disregard the whole of the capital gain or capital loss made on a sale or other disposal of Ordinary Shares or ADSs, unless they, together with any associates (as defined in Australian tax law), hold 10% or more of our issued capital at the time of disposal or throughout a 12 months period during the 24 months prior to disposal.

Non-Australian Investors who own a 10% or more interest in the company, either alone or together with their associates, should be subject to Australian capital gains tax if more than 50% of the company’s assets held directly or indirectly, determined by reference to market value of the assets at the time of sale, consists of Australian real property (which includes land and leasehold interests) or Australian mining, quarrying or prospecting rights. The Double Taxation Convention between the United States and Australia is unlikely to limit the amount of this taxable gain. Australian capital gains tax applies to net capital gains of foreign shareholders at the Australian tax rates for non-Australian residents, which start at a marginal rate of 32.5% for

39

individuals & 25%-30% for companies, depending on the size of the company. Net capital gains of foreign shareholders are included in the taxpayer’s assessable income and subject to income tax at the taxpayer’s marginal tax rate. For the year ended June 30, 2025, the marginal tax rates for non-Australian residents, starts at 30% for individuals. The company tax rate is 30% which may be reduced to 25% for the year ended June 30, 2023 onwards for certain small businesses. Net capital gains are calculated by reducing the taxpayer’s capital gains for the income year by its capital losses, which may only be offset against capital gains. Net capital losses may be carried forward to offset against capital gains derived in future income years. Specific loss recoupment rules apply to companies and trusts. These rules may, among other things, limit the ability to offset or obtain capital losses in a current or future income year. Shareholders should obtain specialist tax advice as to how these rules apply.

The 50% capital gains tax discount is not available to Non-Australian Investors. Companies are not entitled to a capital gains tax discount.

Broadly, where there is a disposal of certain taxable Australian property, the purchaser will be required to withhold and remit to the Australian Taxation Office (“ATO”) 12.5% of the proceeds from the sale. A transaction is excluded from the withholding requirements in certain circumstances, including where the market value of the taxable Australian property is less than A$750,000, the transaction is an on-market transaction conducted on an approved stock exchange, the transaction is in a category of certain securities lending arrangements, or the transaction is conducted using an eligible broker operated crossing system. There is also an exception to the requirement to withhold where the entity selling the shares provides the purchaser a declaration covering a certain period specifying the shares are not taxable Australian property (specifically, not ‘indirect Australian real property interests’). The Non-Australian Investor may be entitled to receive a tax credit for the tax withheld by the purchaser which they may claim in their Australian income tax return. For completeness, the Treasury Laws Amendment (2024 Tax and Other Measures No. 1) Bill 2024, currently before the House of Representatives, proposes to increase the withholding rate from 12.5% to 15%, and remove the $750,000 threshold. These amendments are intended to apply to relevant CGT assets acquired on or after the later of either January 1, 2025 or the enactment of the bill. The progress of this bill should be monitored to confirm it is enacted in its current form.

Tax on Sales or other Dispositions of Shares or ADSs—Revenue Account

Some Non-Australian Investors may hold Ordinary Shares or ADSs on revenue rather than on capital account for example, share traders, or those who hold their shares with a view to deriving a short term profit by selling their shares. These shareholders may have the gains made on the sale or other disposal of the Ordinary Shares and/or ADSs included in their assessable income under the ordinary income provisions of the income tax law, if the income is derived directly or indirectly from Australian sources (which is a question of facts and circumstances generally requiring specialist tax advice).

Non-Australian Investors assessable under these ordinary income provisions should be subject to income tax in Australia starting at a marginal rate of 32.5% for individuals. The company tax rate is 30% which may be reduced to 25% for the year ended 30 June 2023 onwards for certain small businesses. Some relief from Australian income tax may be available to Non-Australian Shareholders under the Double Taxation Convention between the United States and Australia.

To the extent an amount would be included in a Non-Australian Shareholder’s assessable income under both the capital gains tax provisions and the ordinary income provisions, the capital gain amount may be reduced, so that the shareholder may not be subject to double tax on any part of the income gain or capital gain.

Non-Australian Investors holding shares on revenue account should obtain advice on the application of the Australian income tax law and the Double Taxation Convention in determining the tax consequences of the disposal of their shares or ADSs.

40

The comments above in “Tax on Sales or Other Dispositions of Shares and ADSs -Capital Gains Tax” regarding a purchaser being required to withhold 12.5% (potentially increasing to 15% from January 1, 2025 – see above) tax on the acquisition of certain taxable Australian property equally applies where the disposal of the Australian real property asset by a foreign resident is likely to generate gains on revenue account, rather than a capital gain.

Dual Residency

If a shareholder is a resident of both Australia and the United States under those countries’ domestic taxation laws, that shareholder may be subject to tax as an Australian resident. If, however, the shareholder is an individual and determined to be a U.S. resident for the purposes of the Double Taxation Convention between the United States and Australia, the Australian tax may be subject to limitation by the Double Taxation Convention (the tie-breaker rules only apply for individuals). Shareholders should obtain specialist taxation advice in these circumstances.

Stamp Duty

No Australian stamp duty is payable by Australian residents or non-Australian residents on the issue, transfer and/or surrender of the ADSs or the Ordinary Shares in Kazia, provided that the shares issued, transferred and/or surrendered do not represent 90% or more of the issued shares of the Company.

Australian Death Duty

Australia does not have estate or death duties. As a general rule, no capital gains tax liability is realized upon the inheritance of a deceased person’s shares. The disposal of inherited shares by beneficiaries may, however, give rise to a capital gains tax liability if the gain falls within the scope of Australia’s jurisdiction to tax.

Goods and Services Tax

The supply of ADSs or Ordinary Shares in Kazia will not be subject to Australian goods and services tax.

41

PLAN OF DISTRIBUTION

The 8,850,000 ADSs offered by this prospectus are being offered by the Selling Shareholder, Alumni Capital. The shares may be sold or distributed from time to time by the Selling Shareholder directly to one or more purchasers or through brokers, dealers, or underwriters who may act solely as agents at market prices prevailing at the time of sale, at prices related to the prevailing market prices, at negotiated prices, or at fixed prices, which may be changed. The sale of the ADSs offered by this prospectus could be effected in one or more of the following methods:

In order to comply with the securities laws of certain states, if applicable, the ADSs may be sold only through registered or licensed brokers or dealers. In addition, in certain states, the ADSs may not be sold unless they have been registered or qualified for sale in the state or an exemption from the state’s registration or qualification requirement is available and complied with.

Alumni Capital is an “underwriter” within the meaning of Section 2(a)(11) of the Securities Act.

Alumni Capital has informed us that it intends to use one or more registered broker-dealers to effectuate all sales, if any, of the ADSs that it has acquired and may in the future acquire from us pursuant to the Purchase Agreement. Such sales will be made at prices and at terms then prevailing or at prices related to the then current market price. Each such registered broker-dealer will be an underwriter within the meaning of Section 2(a)(11) of the Securities Act. Alumni Capital has informed us that each such broker-dealer will receive commissions from Alumni Capital that will not exceed customary brokerage commissions.

Brokers, dealers, underwriters or agents participating in the distribution of the ADSs offered by this prospectus may receive compensation in the form of commissions, discounts, or concessions from the purchasers, for whom the broker-dealers may act as agent, of the ADSs sold by the Selling Shareholder through this prospectus. The compensation paid to any such particular broker-dealer by any such purchasers of ADSs sold by the Selling Shareholder may be less than or in excess of customary commissions. Neither we nor the Selling Shareholder can presently estimate the amount of compensation that any agent will receive from any purchasers of ADSs sold by the Selling Shareholder.

We know of no existing arrangements between the Selling Shareholder or any other stockholder, broker, dealer, underwriter or agent relating to the sale or distribution of the ADSs offered by this prospectus.

We may from time to time file with the SEC one or more supplements to this prospectus or amendments to the registration statement of which this prospectus forms a part to amend, supplement or update information contained in this prospectus, including, if and when required under the Securities Act, to disclose certain information relating to a particular sale of ADSs offered by this prospectus by the Selling Shareholder, including the names of any brokers, dealers, underwriters or agents participating in the distribution of such ADSs by the Selling Shareholder, any compensation paid by the Selling Shareholder to any such brokers, dealers, underwriters or agents, and any other required information.

42

We will pay the expenses incident to the registration under the Securities Act of the offer and sale of the ADSs covered by this prospectus by the Selling Shareholder.

We also have agreed to indemnify Alumni Capital and certain other persons against certain liabilities in connection with the offering of ADSs offered hereby, including liabilities arising under the Securities Act or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Alumni Capital has agreed to indemnify us against liabilities under the Securities Act that may arise from certain written information furnished to us by Alumni Capital specifically for use in this prospectus or, if such indemnity is unavailable, to contribute amounts required to be paid in respect of such liabilities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons, we have been advised that in the opinion of the SEC this indemnification is against public policy as expressed in the Securities Act and is therefore, unenforceable.

We estimate that the total expenses for the offering will be approximately $3,103,0417.

Alumni Capital has represented to us that at no time prior to the date of the Purchase Agreement has Alumni Capital or its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any short sale (as such term is defined in Rule 200 of Regulation SHO of the Exchange Act) of the ADSs, which establishes a net short position with respect to the ADSs. Alumni Capital has agreed that during the term of the Purchase Agreement, neither Alumni Capital, nor any of its agents, representatives or affiliates will enter into or effect, directly or indirectly, any of the foregoing transactions.

We have advised the Selling Shareholder that it is required to comply with Regulation M promulgated under the Exchange Act. With certain exceptions, Regulation M precludes the Selling Shareholder, any affiliated purchasers, and any broker-dealer or other person who participates in the distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security. All of the foregoing may affect the marketability of the securities offered by this prospectus.

This offering will terminate on the date that all of the ADSs offered by this prospectus have been sold by the Selling Shareholder.

The ADSs are currently listed on the Nasdaq Capital Market under the symbol “KZIA.”

WHERE YOU CAN FIND ADDITIONAL INFORMATION

We have a registration statement on Form F-1 filed with the SEC, including relevant exhibits, under the Securities Act with respect to the securities offered by this prospectus. This prospectus, which constitutes a part of the registration statement, does not contain all of the information set forth in the registration statement or the exhibits. As this prospectus does not contain all of the information contained in the registration statement, you should read the registration statement, its exhibits and the documents incorporated by reference for further information with respect to us and our securities. All information we file with the SEC is available through the SEC’s Electronic Data Gathering, Analysis and Retrieval system, which may be accessed through the SEC’s website at www.sec.gov. Information filed with the SEC may also be inspected and copied at the Public Reference Room maintained by the SEC at 100 F Street, N.E., Washington, D.C. 20549. You can request copies of these documents upon payment of a duplicating fee, by writing to the SEC. Please visit the SEC’s website at www.sec.gov for further information on the SEC’s Public Reference Room.

We are subject to periodic reporting and other informational requirements of the Exchange Act as applicable to foreign private issuers. Our annual report on Form 20-F for the year ending June 30, 2024, has been filed with the SEC and an annual report on Form-20-F for subsequent years will be due within 120 days following the fiscal year end.

We are not required to disclose certain other information that is required from U.S. domestic issuers. As a foreign private issuer, we are exempt under the Exchange Act from, among other things, the rules prescribing the furnishing and content of proxy statements, and our executive officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act and Regulation FD (Fair Disclosure), which was adopted to ensure that select groups of investors are not privy to specific information about an issuer before other investors.

We are, however, still subject to the anti-fraud and anti-manipulation rules of the SEC, such as Rule 10b-5. Since many of the disclosure obligations required of us as a foreign private issuer are different than those required by companies filing as a domestic issuer, our shareholders, potential shareholders and the investing public in general should not expect to receive information about us in the same amount and at the same time as information is received from, or provided by, companies filing as a domestic issuer. We are liable for violations of the rules and regulations of the SEC that apply to us as a foreign private issuer.
