Although the circuit held various rounds of national championships such as the Australian Drivers' Championship and the Australian Sports Car Championship, Winton was not awarded a round of the Australian Touring Car Championship until the start of the Group A era in Australia in 1985.
Richards holds the record for most ATCC round wins at Winton with four, having won in 1985 and 1986 for BMW, while winning in 1990 and 1991 for Nissan.
