1990 Australian Touring Car Championship

The opening three rounds of the championship continued the story of the previous two seasons with the Ford Sierra RS500's of Dick Johnson Racing teammates Dick Johnson (winner of Symmons Plains and Phillip Island) and John Bowe dominating podiums with only the tight nature of the Amaroo Park layout giving another driver a look-in, namely the Nissan Skyline of Jim Richards who held off Bowe in a race long duel to win the season's opening round.

Englishman Percy, a former three time British Touring Car Champion, had taken over the role of team manager and lead driver of the HRT in 1990 and was contesting his first ATCC.

Colin Bond made it two in a row at Mallala after Mark Skaife's spectacular debut of Nissan's new 640 bhp (477 kW; 649 PS), 4WD, twin turbo Skyline R32 GT-R, which was nicknamed "Godzilla", ended with a broken hub after storming to the lead in the early laps.

Ahead of the Oran Park Raceway Grand Finale, Richards held a three-point lead over two-time defending champion Johnson, with Bond and Brock still a chance being eleven and twelve points behind respectively.

Percy was the best of the Holdens in eighth ahead of Alan Jones and Gregg Hansford who only had a partial season in Allan Moffat's Eggenberger Motorsport built Sierra.
