Mercer Australia Pty. Ltd. has appointed TelstraSuper’s long-serving CIO Graeme Miller to a newly created role as CIO of the Mercer Super superannuation fund, overseeing investment strategy design and performance. Miller will be based in Melbourne, Australia, and start in the second quarter of the year.
Mercer Super CEO Claire Ross said Miller’s appointment reflects the fund’s position and future in the superannuation fund sector, noting that it now manages A$74 billion ($46.34 billion) for more than 1 million members.

“A chief investment officer of Graeme’s calibre dedicated to the investment outcomes of our members’ portfolios will help further our position among Australia’s best super funds,” Ross said in a statement.
Given Mercer Super’s size, Kylie Willment, Mercer’s CIO for the Pacific region, explained that now was the right time to bring in its first dedicated CIO “to ensure we remain laser focused on delivering strong retirement outcomes.”
Miller joins from TelstraSuper, where he has been CIO since 2016. TelstraSuper CEO Chris Davies said Miller played a pivotal role in shaping the fund’s investment strategy, delivering strong outcomes for members and driving its approach to sustainable investing.
Notably, according to Rainmaker Information, TelstraSuper’s default investment option returned 8% over 10 years ending December 31, 2024, ranking fifth among measured workplace super options. Rainmaker Information, like CIO, is owned by ISS STOXX.
Following Miller’s resignation, TelstraSuper appointed its head of alternative investments and real assets, Kate Misic, as interim CIO. She joined TelstraSuper in 2010 and has held senior roles across the investment management team, including leading the property, infrastructure, opportunities, hedge fund and private markets asset classes.
“With her proven leadership skills and deep expertise across so many asset classes, Kate is exceptionally well placed to guide our investment strategy for members and build on the strong foundation that Graeme has built,” Davies said in a statement.
Miller’s move comes about two months after TelstraSuper confirmed in December 2024 that it will merge with Equip Super, creating a profit-to-member fund with more than A$60 billion in funds under management and more than 225,000 members.
The successor fund transfer is expected to occur later this year, with full integration anticipated by the end of 2026, at which point the TelstraSuper brand will be retired.
