"I look forward to working with Ian Silk, Heather Ridout and the rest of the Australian Super team to continue delivering high returns to members and promoting the benefits of not-for-profit industrial superannuation funds to all Australian workers," Oliver said.
Oliver is the secretary of the Australian Council of Trade Unions and was elected in 2012.
