Media Super’s chief executive officer (CEO), Graeme Russell, will step down from his role on 9 April, 2020, after seven years at the helm.
It said Russell and the board had agreed to a transitional arrangement to help Russell focus on recovery after a recent serious illness.
His position would be filled by chief operation officer, Tony Griffin, who was acting CEO while Russell took time off last year for his illness.
Russell said it had been a great privilege to be CEO of the fund.
"I think it's disappointing that government and the regulators don't understand the important contribution that industry-specific super funds make to their industries, beyond superannuation", he said.
"We're about to see that clearly, as funds like Media Super step-up to support members and companies struggling through the current economic dislocation and job losses.”
Media Super chairperson, Gerard Noonan said Russell’s work was a driving force behind the fund’s “spectacular reversal of investment performance in recent years”.
"With Media Super's small investment team and supported by our Board, Graeme has been instrumental in single-mindedly recommending strategies - and executing them - to push our performance into the winner's circle," Noonan said.
"Graeme is now well into recovery but has decided to ease back on work commitments."
