PROSPECTUS SUPPLEMENT
(to Prospectus dated January 26, 2023)

Iris Energy Limited
Up to 25,000,000 Ordinary Shares

This prospectus supplement supplements the prospectus dated January 26, 2023 (the “Prospectus”), which forms a part of our registration statement on Form F-1 (No. 333-267568). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our report on Form 6-K, filed with the Securities and Exchange Commission on July 18, 2023 (the “Report”). Accordingly, we have attached the Report to this prospectus supplement.

This prospectus supplement relates to the potential offer and sale from time to time by the securityholder named in the Prospectus (the “Holder”) of up to 25,000,000 of our ordinary shares, with no par value (the “Ordinary shares”), that have been or may be issued by us to the Holder pursuant to an ordinary shares purchase agreement, dated as of September 23, 2022, by and between us and the Holder establishing a committed equity facility. We are not selling any securities under the Prospectus and will not receive any of the proceeds from the sale of our Ordinary shares by the Holder.

Our Ordinary shares are listed on the Nasdaq Global Select Market under the symbol “IREN”. On July 17, 2023, the last reported sale price of our Ordinary shares was $7.03 per Ordinary share.

This prospectus supplement updates and supplements the information in the Prospectus and is not complete without, and may not be delivered or utilized except in combination with, the Prospectus, including any amendments or supplements thereto. This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement. If there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

We are both an “emerging growth company” as that term is used in the Jumpstart Our Business Startups Act of 2012 and a “foreign private issuer” as defined under the U.S. federal securities laws and, as such, have elected to comply with certain reduced public company reporting requirements.

Investing in our securities involves a high degree of risk. You should carefully review the risks and uncertainties described in the section titled “Risk Factors” beginning on page 16 of the Prospectus, and under similar headings in any amendments or supplements to the Prospectus, including this prospectus supplement.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus supplement. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is July 18, 2023.
