The stadium, which is sometimes referred to as Sydney Olympic Stadium, Homebush Stadium or simply the Olympic Stadium, was completed in March 1999 at a cost of A$690 million to host the 2000 Summer Olympics. The Stadium was leased by a private company, the Stadium Australia Group, until the Stadium was sold back to the NSW Government on 1 June 2016 after NSW Premier Michael Baird announced the Stadium was to be redeveloped as a world-class rectangular stadium. The Stadium is owned by Venues NSW on behalf of the NSW Government.
