Sydney Olympic stadium or Stadium Australia, currently known as ANZ Stadium is a multi-purpose stadium located in the Sydney Olympic Park. Sometimes it is referred to simply as the "Olympic Stadium", was completed in March 1999 at a cost of A$690 million to host the 2000 Summer Olympics.
The stadium was originally built to temporarily hold 110,000 spectators, making it the largest Olympic Stadium ever built as well as the largest stadium in Australia. But, for several reasons the actual capacity was reduced to 83,500 for a rectangular field and 81,500 for an oval field (making it the second largest stadium in Australia after the Melbourne Cricket Ground).
