AustralianSuper Chief Investment Officer and Deputy CEO Mark Delaney will step down from his roles on June 30, 2026, ending a 25-year tenure with the country's largest superannuation fund.
The fund confirmed on Dec. 16 that a global search for Delaney's successor will be conducted over the next six months.
Delaney has been a central figure in AustralianSuper since its establishment in 2006, working alongside former CEO Ian Silk and serving as both CIO and deputy CEO since July 1 that year.
He previously led the Superannuation Trust of Australia prior to its merger with AustralianSuper and has held senior roles at National Mutual/AXA and the federal Treasury.
He is also a director on IFM Investors' advisory board. AustralianSuper chief executive Paul Schroder credited Delaney with overseeing the expansion of member assets from about $20 billion at the fund's inception to more than $400 billion today, noting that roughly $190 billion of that growth came from investment returns achieved under Delaney's leadership.
Schroder described Delaney as a "truly member-centric investor" whose measured approach delivered strong outcomes through multiple economic cycles.
Delaney said AustralianSuper had transformed superannuation investing in Australia by becoming a more active, globally diversified investor, enabling members to access world-class investment opportunities at scale.
