In a statement, Queensland-based super fund LGIAsuper announced that Mr Dewhurst would replace former director John Wilson on the board.
Mr Dewhurst joined Legg Mason in 2008 and departed his position as head of international asset management in 2013.
Prior to that, he was IOOF’s chief executive from 2004 to January 2007.
He also has experience serving on the boards of listed and unlisted companies, and is currently a director at One Vue and Rhinomed.
LGIAsuper chair John Smith welcomed Mr Dewhurst to the board.
“Mr Dewhurst’s experience in global investment banking and asset management will strengthen the Board’s ability to generate strong returns for our members, while managing risk appropriately,” Mr Smith said.
LGIAsuper has $11 billion funds under investment on behalf of 85,000 members.
