Sydney Entertainment Centre, later known as Qantas Credit Union Arena, was a multi-purpose arena located in Haymarket, Sydney, Australia. It opened in May 1983, to replace Sydney Stadium, which had been demolished in 1970 to make way for the Eastern Suburbs railway line. The centre was owned by the Sydney Harbour Foreshore Authority, which administered the neighbouring Darling Harbour area, and managed under a lease.

Darling Harbour is a harbour adjacent to the city centre of Sydney, New South Wales, Australia that is made up of a large recreational and pedestrian precinct that is situated on western outskirts of the Sydney central business district.
