With Australia in the middle of a economic downturn (the "Recession we had to have" according to Federal Treasurer Paul Keating), entry numbers were significantly down on 1990 at almost every round, with only eleven cars appearing at Wanneroo Raceway. Notable absentees included Allan Moffat Racing and Toyota Team Australia, while Peter Brock closed his Mobil 1 Racing team (effectively bringing to an end the old Holden Dealer Team which had been around since 1969) and took his Mobil sponsorship to Perkins Engineering, reuniting with his Bathurst 1000 winning co-driver of 1982, 1983 and 1984, Larry Perkins in a pair of new Holden VN Commodore SS Group A SV's.
