The Gold Coast 600 is an annual V8 Supercars event held each October at the Surfers Paradise Street Circuit in Surfers Paradise, Queensland, Australia. The race is currently known for sponsorship reasons as the Castrol Gold Coast 600, and was formerly known as the V8 Supercar Challenge from 1997 to 2009.
First run in 1994, the event was a support race to the Gold Coast Indy 300 until its demise in 2009.
The Gold Coast, of which Surfers Paradise is a suburb, had long had an association with touring cars through Surfers Paradise International Raceway in the suburb of Carrara. The track held numerous rounds of the Australian Touring Car Championship (ATCC), the previous incarnation of V8 Supercars, between 1969 and 1987.
The Gold Coast Indy 300 was first run in 1991, however it was not until 1994 that touring cars joined the event. The event, featuring cars from the ATCC, was run as a non-championship exhibition round, supporting the then CART FedEx Championship Series event. In the next two years, cars from the two-litre Australian Super Touring Championship were a support category at the event; in 1995 as the sole touring car category and in 1996 one of two touring car support categories alongside the return of the ATCC cars.
