SYDNEY, Australia (26 April 2023) – Ryan, a leading global tax services and software provider, has announced that Jason Dunnachie has joined the Firm as a Principal and Practice Leader of the Research and Development (R&D) practice in Australia. Based in Sydney, he will work with clients across Australia, Asia-Pacific, and worldwide.

“Jason is a prominent leader in the Research and Development sector in the Asia-Pacific region,” said Jon Sweet, Ryan President of European and Asia-Pacific Operations. “By combining the strength of Ryan’s existing R&D practice with Jason’s professional background, knowledge of the R&D space, and leadership capabilities, our R&D practice is poised to lead the industry and better serve clients in Australia and worldwide.” 

Dunnachie assists clients across all industries and of varying sizes. He has an excellent track record in successfully defending contested claims via negotiation, and when necessary, litigation. A leading expert in innovation and investment incentives, Dunnachie is at the forefront of policy discussions and has contributed to the debate on R&D tax incentive reform.  

“I am excited to have joined a firm with a true global outlook,” said Dunnachie. “Ryan’s approach to working with global clients and enabling teams to work across borders is something that other firms can only aspire to.”
