Dear Dr. Tarnoff,

I am pleased to confirm our offer regarding your appointment as a non-executive member (a “Non-Executive Director”) of the Board of Directors (the “Board”) of AVITA Medical, Inc., a Delaware corporation (the "Company"), which will commence effective August 6, 2025 (the “Effective Date”), on the following terms:

Your position as a Non-Executive Director will require formal acceptance of this appointment, by executing this letter agreement as of a date no later than July 15, 2025. Upon receipt of your executed copy of this letter agreement, the Board will act formally to elect you effective as of the Effective Date, after which the Board Secretary will provide you with relevant documents and other on-boarding information. Your term as a Non-Executive Director will commence on the Effective Date, and you will be subject to annual re-election at the Company’s annual shareholder meeting which takes place on or around June of each year.

In consideration for your services to the Company as a Non-Executive Director, your remuneration is comprised of an annual cash component of US $70,000, with additional cash fees paid for participation on one or more Board committees to be discussed in due course. The equity component of your remuneration is comprised of an initial equity grant equal in value to $210,000, with 30% granted as stock options and 70% granted as restricted stock units. Starting in 2026, your remuneration will be comprised of an annual equity grant component equal in value to $125,000, with 30% granted as stock options and 70% granted as restricted stock units. Remuneration for Non-Executive Directors is reviewed periodically by an outside consulting firm with reference to board compensation of peer companies, and the equity component of Non-Executive Director remuneration is subject to approval at the Company’s annual shareholder meeting.

As a Non-Executive Director, you are entitled to reimbursement for reasonable Company-related expenditures incurred by you, including your travel to and from Board meetings, after receipt by the Company of an itemized expense report, together with receipts or other reasonable proof of such expenses. Travel is typically coordinated through the office of the Company’s Chief Executive Officer.

You agree that you will (i) hold in strictest confidence the Company's proprietary information and trade secrets and all other information made known to you in connection with your relationship with the Company as a Non-Executive Director that has or could have commercial value or other utility in the Company's business or prospective business (collectively, the "Confidential Information"), and (ii) not use the Confidential Information except in connection with your relationship with the Company as a Non-Executive Director.

The Confidential Information will not include information that you can establish is or was (i) received by you from an unrelated third party, without an obligation of confidentiality or other legal obligation to disclose it, (ii) generally known or available in the industry or to the general public either (A) prior to the Company's disclosure of such information to you or (B) after the Company's disclosure of such information to you through no action or inaction by you, or (iii) required to be disclosed by applicable law or order of a court, or in accordance with the rules, regulations or order of any governmental agency.

You agree that you will not improperly use or disclose any proprietary information or trade secrets received by you from any third party in connection with your relationship with the Company as a Non-Executive Director. You recognize that the Company has received, and in the future will receive, confidential and proprietary information from third parties and that the Company will have a duty to maintain the confidentiality of such information and to use it only for certain limited purposes. You agree to hold all such confidential and proprietary information in the strictest confidence, and you further agree that you will neither disclose it to any person, firm or corporation nor use it in a manner that is inconsistent with the Company's obligations to such third parties.

To the extent that your service to the Company results directly in the creation of any new Intellectual Property (as defined below), you agree that, as between you and the Company, the Company shall own the rights to such new Intellectual Property if such Intellectual Property (i) is developed using the equipment, facilities, supplies or the Confidential Information of the Company, or (ii) results from, or is suggested by, work performed by you on behalf of the Company, but only if you are explicitly engaged in performing direct work for the Company. For the purposes of this section, "Intellectual Property" means any original works of authorship, inventions, concepts, improvements or trade secrets, whether or not patentable or registrable under copyright or similar laws. At the Company's expense, you agree to execute all documents and take all actions necessary or reasonably requested by the Company to document, perfect or assign the Company's rights to Intellectual Property. Further, if you fail or refuse to execute any such instruments, you hereby appoint the Company as your attorney-in-fact (this appointment to be irrevocable and a power coupled with an interest) to act on your behalf and to execute such documents.

Upon the Company's request at, and after, such time as your term as a Non-Executive Director terminates, you agree to return, and will not keep in your possession, recreate or deliver to any third party, any and all documents and/or electronic files containing the Confidential Information.

The Company will agree to defend and indemnify you and hold you harmless against liability that you incur within the scope of your service as a Non-Executive Director of the Company to the fullest extent provided under Delaware law, and pursuant to and in accordance with all of the terms and conditions contained in the Indemnification Agreement on the Company’s standard form to be separately provided to you, which is to be executed and delivered by you and the Company upon execution and delivery of this letter agreement. in addition, the Company currently holds Directors & Officers Liability coverage with (i) Side A Difference in Conditions coverage of personal asset protection for a director or officer for non-indemnifiable claims, (ii) coverage B for corporate asset protection for amounts it pays to a director or officer through indemnification, and (iii) coverage C which provides corporate asset protection for securities claims against the Company for a total $30M limit.

You and the Company agree to cooperate with each other to create any and all appropriate public or promotional announcements or press releases concerning our relationship.

This letter agreement will commence on the Effective Date and will continue until such time as your term as a Non-Executive Director terminates. Upon such termination, all our rights and duties towards each other shall cease, except that this Section 9, together with Sections 5, 6, 7, and 10, shall survive termination of this letter agreement.

Please acknowledge your agreement to these terms by signing and dating a copy of this letter
