Sydney Olympic Park is a suburb of Greater Western Sydney, located 13 kilometres west of the Sydney central business district, in the local government area of the City of Parramatta Council. It is commonly known as Olympic Park but officially named Sydney Olympic Park. The area was part of the suburb of Lidcombe and known as "North Lidcombe", but between 1989 and 2009 was named "Homebush Bay". The names "Homebush Bay" and, sometimes, "Homebush" are still used colloquially as a metonym for Stadium Australia as well as the Olympic Park precinct as a whole, but Homebush is an older, separate suburb to the southeast, in the Municipality of Strathfield.
Sydney Olympic Park features a large sports and entertainment area, originally redeveloped for the Sydney 2000 Olympic and Paralympic Games. The stadiums, arenas and venues continue to be used for sporting, musical, and cultural events, including the Sydney Royal Easter Show, Sydney Festival and a number of world-class sporting fixtures. The suburb also contains commercial developments, residential buildings and extensive parklands.
