The race, which was Round 2 of both the 1990 Australian Endurance Championship and the 1990 Australian Manufacturers' Championship, resulted in an upset victory for British driver Win Percy and 1986 Bathurst 1000 winner Allan Grice in a Holden Racing Team entered Holden Commodore over the Dick Johnson Racing Ford Sierra of Jeff Allam and Paul Radisich and the Perkins Engineering Holden Commodore of Larry Perkins and Tomas Mezera.
