EXPLANATORY NOTE

This Amendment No. 1 to Form 20-F (the Form 20-F/A) amends the Annual Report on Form 20-F of Kazia Therapeutics Limited (formerly known as
Novogen Limited) for the fiscal year ended June 30, 2017, originally filed with the U.S. Securities and Exchange Commission (SEC) on October 25, 2017 (the Form 20-F). The sole purpose of this Form 20-F/A is to amend
the Form 20-F to replace the original Exhibits 4.11, 4.13 and 4.14 to the Form 20-F (the Original Exhibits) with the new Exhibits 4.11, 4.13 and 4.14 attached to this Form 20-F/A (the New Exhibits) in response to
comments received from the SEC on a confidential treatment application. The New Exhibits reinstate information that was redacted in the Original Exhibits for which confidential treatment is no longer requested and replace in their entirety the
Original Exhibits. The amendments to the Original Exhibits that are made in the New Exhibits are as follows:



|(i) | the redacted terms in the definitions of Milestone 1 Shares and Milestone 2 Shares in Section 1.1 of Exhibit 4.11 have been restored;
|--- | -----------------------------------------------------------------------------------------------------------------------------------------



|(ii) | the redacted total amount in the Instalment column of the table in Section 2 of Schedule 4 to Exhibit 4.13 has been restored;
|---- | -------------------------------------------------------------------------------------------------------------------------------



|(iii) | the redacted total amounts under Cash in the first rows of the first and third tables in Section 3 of Schedule 4 to Exhibit 4.13 have been restored; and
|----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------



|(iv) | the redacted total amounts under Cash in the first rows of the first and third tables in Section 1 of Schedule 3 to Exhibit 4.14 have been restored.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------

Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Form 20-F/A also contains new certifications pursuant to Section 302 of
the Sarbanes-Oxley Act of 2002. Because no financial statements have been included in this Form 20-F/A and this Form 20-F/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the
certifications have been omitted.

No other changes have been made to the Form 20-F. The Form 20-F, as amended by this Form 20-F/A, speaks as of the
original filing date of the Form 20-F, does not reflect events that may have occurred subsequent to the original filing date of the Form 20-F, and does not modify or update in any way the disclosures made in the Form 20-F.
