AustralianSuper Chief Investment Officer stepping down after 25 years at the Fund

16 December 2025

AustralianSuper today announced Chief Investment Officer and Deputy Chief Executive Mark Delaney will step down after 25 years with the Fund.

Mr Delaney will remain in his role until 30 June 2026, during which time the Fund will conduct a global search for his replacement.

AustralianSuper Chief Executive Paul Schroder said Mark’s enormous and continued contribution to both AustralianSuper and the broader superannuation sector was unparalleled.

‘By building and leading a high performing global team Mark has made more money for more Australians than any super fund chief investment officer in the country,’ Mr Schroder said.

‘Since the Fund was established in 2006, Mark has overseen the growth in member assets from around $20 billion to more than $400 billion today.

‘Around half that growth was due to investment returns achieved under Mark’s leadership, or around $190 billion.

‘Mark has always been a truly member centric investor, his calm, thoughtful and considered approach to everything he does has seen him deliver for members through economic cycles.

‘He is known for his deep commitment to his colleagues, generous approach to mentoring a generation of leaders, and his characteristic warmth and sense of humour.

‘Mark has also been a critical contributor to the evolution of Australia’s world class super system.

‘His leadership is evident in decisions such as the introduction of portfolio holdings disclosure well before it was a regulatory requirement, playing a more active role in the stewardship of investee companies, and bringing more investment management in house to help deliver better returns for members.

‘AustralianSuper led industry change in all these areas thanks to Mark’s vision and dedication.

'AustralianSuper members, our colleagues, and our financial partners will miss him.'

Mr Delaney said it was the right time to bring to a close his long tenure with AustralianSuper, a fund he and former CEO Ian Silk played a pioneering role in establishing.

'It’s been an honour every day from the day I started, but I've decided it's time to go,' Mr Delaney said.

‘Until I call time with the Fund in June, I will work my hardest to get members the returns they deserve.

‘I am extremely proud of what AustralianSuper has achieved for members and I've been lucky to work with some of the most talented people in the financial services industry.

‘We transformed superannuation investing in Australia by becoming an active investor in a range of asset classes and building a globally diversified portfolio so every member can now invest in world class opportunities at scale.

‘Our goal has always been to earn the trust of members and deliver for them, and we never take their trust for granted.’
