The VHT S5000 Australian Drivers' Championship (known originally as the Australian S5000 Championship, or simply S5000) is a current open-wheel road racing series in Australia. The series was created by a merger between two proposed series, Formula Thunder 5000 and Super5000. The series is promoted by the Australian Racing Group. The inaugural race of the series was originally set to be in Sydney Motorsport Park in May 2019, but was delayed to September due to supply issues from Ligier's Charlotte area factory where the chassis are manufactured.
