Industry funds QSuper and Sunsuper have set a revised merger date for November 2021.
The merger was announced earlier this year with Sunsuper chief executive, Bernard Reilly, to be the new chief executive.
A spokesperson for Sunsuper said: “Since signing the heads of agreement in March, we have progressed our plans to create a $200 billion superannuation fund, headquartered in Queensland, open to all Australians.
“To ensure the success of our planned merger, we have revised the target merger date to November 2021.
“This is six weeks later than the original objective announced in March, a reflection of the size, scale and complexity of the transaction which is intended to benefit two million members.
“Trustees of each fund believe this is in the best interests of our combined membership, to ensure a seamless experience.”
