Former Labor powerbroker Mark Arbib has been unveiled as the new chief executive of the Australian Olympic Committee. Arbib, who has served on the AOC executive since 2016, will replace outgoing chief executive Matt Carroll, whose eight-year tenure ends next month at the organisation’s annual general meeting. Athletics Australia’s president for six years until 2021, Arbib edged out former Cricket Australia chief executive Nick Hockley and Commonwealth Games Australia president Ben Houston for one of the most significant roles in Australian sport. Arbib held several ministerial portfolios, including minister for sport and assistant treasurer, before he resigned from politics in 2012.
