Adelaide

Adelaide was awarded a round of the 1985 Formula One World Championship in October 1984, with construction of the circuit by Macmahon Holdings. The first event was held in 1985 as the final event of the season. The circuit incorporated a purpose-built section of road in the center of Victoria Park Racecourse and surrounding city roads. The Adelaide event was the scene of dramatic moments, including Nigel Mansell's tyre blowing loss of the World Championship in 1986, and Ayrton Senna's final victory at Adelaide in 1993. Michael Schumacher took his first championship on the South Australian streets in 1994. The last Formula One race at the circuit was held in 1995, after which the rights were lost to Melbourne and the event moved to the Albert Park Street Circuit.

During Adelaide's Formula One era, the circuit hosted annual non-championship races for Group A and later Group 3A touring cars. From 1999 until 2020 and again from 2022, a shortened 3.219 km version of the circuit has been used for the Adelaide 500 touring car race. The event became one of the most acclaimed on the Supercars calendar and is the only event added to the Supercars Hall of Fame. The circuit was shortened slightly for the Adelaide 500, with the section from Hutt Street and Rundle Road bypassed in favor of a new straight along Bartels Road. The event returned in 2022 as the season finale for the Supercars Australia series, having previously usually been the opening event. The resumed Adelaide 500, with naming rights sponsorship from VALO, took place on December 1-4, 2022, as the season finale of the Repco Supercars Championship.

The Adelaide Street Circuit commences pit straight in Victoria Park. It is 500 m long and faces northwest. At the end of the straight, drivers negotiate the Senna Chicane, named after Ayrton Senna. The full Grand Prix circuit includes a sweeping left-right-right into Stag Turn (turn 9), which leads onto the 360 m long Rundle Road, named after Alan Jones in 1987. The Dequetteville Terrace straight, named after Jack Brabham for Formula One and Peter Brock for the Adelaide 500, was a 900 m stretch. The short form of the track rejoins Brabham Straight two-thirds of the way down, making the 640 m long Bartels Road straight the longest on that layout. In 2007, this section of track was renamed Brock Straight after touring car driver Peter Brock. The track is essentially flat except for a small valley on the Brock Straight and a slight incline on Jones Straight.

In 2000, the long-form of the course was revived for a round of the American Le Mans Series. Held on New Year's Eve, the event was titled the 'Race of 1000 Years' and was won by the Audi R8 of Rinaldo Capello and Allan McNish. Between 2014 and 2018, an annual Adelaide Motorsport Festival ran on the Victoria Park Sprint Circuit, a shortened 1.4 km layout. The event returned on March 24–26, 2023, and was also held on March 15–17, 2024.

Adelaide is scheduled to host the Australian Motorcycle Grand Prix from 2027, using a heavily modified version of the Formula One Circuit.

The fastest ever recorded lap of the original 3.780 km Grand Prix Circuit was 1:13.371 by Ayrton Senna driving a McLaren MP4/8 Ford during qualifying for the 1993 Australian Grand Prix. The fastest officially recorded lap of the 3.219 km Supercars circuit is 1:16.0357 set by Aaron Cameron on November 24, 2023, driving a Rogers AF01/V8 in the 2023 S5000 Australian Drivers' Championship. The fastest recorded lap of the 1.4 km Victoria Park Sprint circuit is 0:42.5753 set by Ivan Capelli on December 2, 2018, driving a March CG891 car from the 1989 Formula One season.
