INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On April 13, 2023, Kazia Therapeutics Limited (the “Company”) received a letter from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) confirming the Company has regained compliance with Nasdaq’s minimum bid price requirement under Listing Rule 5550(a)(2). The Company previously received notification on December 9, 2022, that its American Depository Shares (ADSs) were not in compliance with Nasdaq’s minimum bid price requirement, having closed at a price below US$ 1.00 per share for thirty consecutive business days. In the letter received on April 13, 2023, the Staff determined that, during the ten consecutive business days from March 29, 2023 to April 12, 2023, the closing bid price of the company’s ADSs has been at $1.00 per share or greater and accordingly, the Company has regained compliance with Listing Rule 5550(a)(2). The Company also issued an ASX announcement titled, “Kazia Regains Compliance with Nasdaq Minimum Bid Price Requirement.” A copy of this release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The Company hereby incorporates by reference the information contained herein, including Exhibit 99.1, into the Company’s registration statement on Form F-3 (File No. 333-259224).
