Matthew Benter was elevated from an ordinary member, which he has served in since August 2023, to a senior member.

He has held senior roles with the Federal Court of Australia, the private sector and the Australian Securities Commission.

 
 

Former acting registrar and arbitrator of the Workers Compensation Arbitration Service, Richard Yates, has moved into the position of ordinary member of the SAT.

Yates has significant experience in tribunal decision making, litigation, and public service, developed over more than two decades in legal practice and statutory decision making.

“The State Administrative Tribunal performs an important role in delivering accessible, fair and timely resolution of disputes and reviews that affect Western Australians.

“I congratulate Matthew Benter and Richard Yates on their appointments and welcome the experience and expertise they will bring to the tribunal,” Attorney-General Dr Tony Buti said.

Buti has also approved the reappointment of John O’Sullivan as a senior member and Nova Oldfield and Rosetta Petrucci as ordinary members of the SAT.

O’Sullivan has served as a senior member since 2021, following a career on the bench of the Magistrates Court of Western Australia.

Oldfield and Petrucci have each made valuable contributions across a range of SAT jurisdictions and bring extensive experience in conducting hearings, mediations, and delivering decisions.

“I also congratulate John O’Sullivan, Nova Oldfield and Rosetta Petrucci on their reappointments and thank them for their continued service to the WA community.

“Together, these appointments and reappointments will help ensure SAT continues to deliver high-quality outcomes while maintaining the efficient operation of Western Australia’s tribunal system,” Buti said.
