Sydney Motorsport Park, Motorsport racing track in Eastern Creek, New South Wales, Australia

Sydney Motorsport Park is a racing track in Eastern Creek, a western suburb of Sydney in New South Wales. The complex features several circuit configurations, including the Gardner GP Circuit, Brabham Circuit, Druitt North Circuit, and Amaroo South Circuit.

Construction of the circuit was approved in 1989, and it opened on 10 November 1990 when Bob Rowland-Smith, then New South Wales Minister for Sport, started the Nissan Sydney 500 endurance race for Group A touring cars. The Australian Motorcycle Grand Prix was held here from 1991 to 1996, after a dispute over tobacco advertising moved the race from Phillip Island. In 1991 the New South Wales Government bought the complex after its funding consortium ran into financial problems.

The track has carried the name Sydney Motorsport Park since 2012, after being known as Eastern Creek International Raceway before. Visitors can watch different racing disciplines during competition weekends and explore the paddock area.

The circuit lies about 40 km west of central Sydney on Brabham Drive in Eastern Creek, next to the Western Sydney International Dragway. Its pit building has fifty garages opening directly onto the paddock, and a covered grandstand seats 4,000 people overlooking the finish line and most of the track. Events run most weekends of the year.

The circuit holds both an FIA Grade 2 licence and an FIM Class B licence, the only permanent track in Australia with that pair of gradings. Its corners carry drivers' names: turns one and two became Moffat Corner and Bond Bend in October 2017, and turn five is Brock's 05, after Peter Brock.
