We have acted as special Nevada counsel for Kintara Therapeutics, Inc., a Nevada corporation (the “Company”), in connection with the Company’s filing of a Registration Statement on Form S-3 (as amended or supplemented, the “Registration Statement”) filed on March 24, 2021, effective April 1, 2021 (File No. 333-254662) with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”). We are delivering this supplemental opinion letter in connection with the Prospectus Supplement filed on September 19, 2023 (the “Prospectus Supplement”), by the Company with the Commission pursuant to Rule 424 under the Securities Act. The Prospectus Supplement relates to the offering by the Company of up to $2,850,000 in shares of the common stock of the Company, par value $0.001 (the “Shares”), covered by the Registration Statement. The Shares are being offered and sold by A.G.P./Alliance Global Partners as sales agent (the “Sales Agent”) pursuant to the Sales Agreement between the Company and the Sales Agent dated September 19, 2023 (the “Sales Agreement”).

The Articles of Incorporation of the Company, as amended, as certified by an officer of the Company as of the date hereof;

The Bylaws of the Company, as certified by an officer of the Company as of the date hereof; and

Resolutions of the Board of Directors of the Company, adopted by the Board of

Directors of the Company via unanimous written consent on September 13, 2023 and September 18, 2023, relating to the authorization of the Sales Agreement, and the issuance of the Shares, as certified by an officer of the Company as of the date hereof.

We have examined originals or copies of such corporate records and certificates of public officials as we have deemed necessary or advisable for purposes of this opinion.

We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of natural persons and the conformity to originals of all copies of all documents submitted to us. We have not reviewed, and express no opinion as to, any instrument or agreement referred to or incorporated by reference in the documents listed above. We note that the Company has reserved, and assume it will continue to maintain reserved, a sufficient number of shares of its duly authorized, but unissued, common stock as is necessary to provide for the issuance of the Shares.

Based on and subject to the foregoing and the qualifications, limitations, exceptions and assumptions set forth below, it is our opinion that the Shares have been duly authorized and, when issued and paid for in accordance with the terms of the Sales Agreement, will be validly issued, fully paid and non-assessable.
