Australian Refrigeration Council (ARC) announces new appointments

The Australian Refrigeration Council (ARC) is pleased to announce the appointment of Mark Lamb as its new Chief Executive Officer (CEO) and Susie O’Neill as the new Deputy CEO, commencing 4 May 2026. 

Mr Lamb brings decades of diverse leadership experience across various sectors, both domestically and internationally. Most recently, he served as the Chief Executive Officer of the Murray-Darling Association. Previously, Mr Lamb has held several executive roles with distinct peak body organisations, where he worked closely with government and industry. During his tenure, assisted many organisations to transition into new strategies and methodologies. With his notable experience, he is well positioned to lead the ARC at a time when the refrigeration and air conditioning (RAC) industry is growing at a rapid pace.


Mr Lamb succeeds Glenn Evans, who concluded his tenure in December 2025 after 17 years of service.


ARC Chair Dr Greg Picker said he was pleased to welcome Mr Lamb to mark the next phase for the Council, which leads national governance of the RAC (also known as ARCtick) Permit Scheme.


“The Board is pleased to appoint Mark Lamb as our new CEO. We look forward to working with him as we continue to deliver the ARCtick permit scheme and improve our service to industry. His passion and experience in leading peak body organisations perfectly aligns with the ARC’s priorities at this time and our vision for the future,” Dr Picker said.


“It is a crucial time for the industry, and the Board is confident Mark will help us build on our momentum and continue deliver meaning outcomes for the ARC and the broader industry.”



Commenting on his appointment, Mr Lamb said, “I am thrilled to be given this opportunity to play this significant role, not just at the Australian Refrigeration Council, but in the refrigeration and air conditioning industry.
