Australian Retirement Trust, Brisbane, promoted Nick Horn to head of investment risk and Bridget Piggott to head of risk, a spokeswoman confirmed.
Both are new roles and are part of changes in the risk and compliance team structure, she said. They started in their roles earlier this month.
"These are internal appointments and the changes are designed to make it simpler for the risk and compliance team to deliver outcomes across ART," she said.
Mr. Horn reports to Anne Browne, chief risk officer, while Ms. Piggott reports to Dianna Orbell, general manager for risk and assurance.
ART, which has A$240 billion ($161 billion) in assets, said in a statement in March that it was hiring for a head of investment resilience and planning role as part of its leadership restructuring. The spokeswoman did not respond to questions about whether Mr. Horn had taken this role.
Mr. Horn has around 20 years experience in investment management, banking and insurance companies. He was previously an investment risk manager at Sunsuper and ART, then senior manager for investment risk and compliance at ART.
Ms. Piggott was a senior risk manager with QSuper and ART since 2016. She joined QSuper in 2011 and was a compliance manager at Citibank for five years before that.
The fund has been fine-tuning its leadership and executive structures since its formation through the merger of Sunsuper and QSuper last year. As part of the restructuring, Stevhan Davidson was made chief strategy officer, and the firm was hiring for a new chief of retirement and chief member officer in March.
