After 12 years as CIO, Graham announced his intention to step down from the role in May to become head of international, with plans to retire completely within the next few years. He has since announced that he will instead commence as as group chief investment officer at Challenger, effective January 2026.
A comprehensive global search by the super fund for his replacement has been underway since May.
Warner, who joined Aware Super in 2023 as head of portfolio management, will lead the fund’s 160-person investment team that manages its members’ $205 billion superannuation savings across equities, fixed income, infrastructure, property, and private equity.
Commenting on Warner’s appointment, Aware Super CEO Deanne Stewart said it guarantees the continuity of the fund’s investment strategy and robust governance frameworks.
“Simon has demonstrated exceptional leadership during his two years at Aware Super, contributing to our track record of delivering outstanding returns for members,” Stewart said.
“He has significant global experience, deep expertise across public and private markets, a strong focus on governance and risk management, and a proven ability to lead large, high-performing teams.”
Before joining Aware, Warner held several executive positions, including global head of public markets at AMP and, prior to that, as global CIO and co-head of global equities and fixed income.
He also previously served as CIO for Australia and New Zealand at JPMorgan Chase, among other senior positions at the firm held across London, Singapore, and Sydney.
Warner’s educational background includes a global executive MBA from TRIUM (NYU Stern, LSE, and HEC Paris), as well as both master’s and bachelor’s degrees in economics from the London School of Economics. He has also held various board positions, including his current directorship with Women in Banking and Finance.
Looking forward, Stewart said Warner’s expertise would be invaluable in supporting the super fund’s next phase of growth.
“As we continue to grow, I am confident that Simon’s leadership will enable us to further strengthen our exceptional in-house investment team’s capability and ensure we’re delivering the best possible outcomes for our members’ retirement savings,” she concluded.
Warner will commence in his new capacity from 1 December.
