Championship review
winner Alan Jones moved back to Formula One in 1983 and did not defend his title. His main opposition from 1982 returned, including, Rusty French in the ex-Jones Porsche 935 sponsored by John Sands, along with new team-mate Alan Browne in the ex-French 935. Twice former Australian Sports Sedan Champion Tony Edmondson fronted again in the Don Elliot owned, 5.0L Chevrolet powered, Alfa Romeo Alfetta GTV, while touring car driver Peter Brock again was to drive the Bob Jane owned 6.0L Chevrolet Monza. Also competing were the Frank Gardner run JPS Team BMW with Jim Richards driving the team's turbocharged BMW 318i that had originally been driven by Allan Grice, Adelaide based John Briggs who had sold his Monza and was running an ex-JPS BMW 318i, and Peter Fitzgerald in his 3.2L Naturally aspirated Porsche Carrera RSR. The expected challenge from the twin-turbo Chevrolet V8 powered Mercedes-Benz 450 SLC of Bryan Thompson failed to eventuate until late in the series as the car was plagued by unreliability.The third round of the championship at the Adelaide International Raceway was the scene of a start line accident after the Chevrolet Monza of Peter Brock snapped left off the line and speared into the concrete wall before bouncing back in front of the field. With nowhere to go and little time to react, others, led by Jim Richards crashed into Brock, with the ex-Jim Richards Ford Falcon of Tony Hubbard ending up on top of the pile and the Jaguar XJS of Queensland's Mark Trenoweth on the bottom. Reports varied from the Jane camp about the cause of the crash. Peter Brock maintained that the car had broken a CV joint while chief mechanic Pat Purcell believed the cause was actually Brock just losing control when the car found sudden grip, claiming that nothing had broken on the car before the crash. At least one third of the field was eliminated in the crash. Following the accident, neither the Monza nor the JPS BMW were raced until November at the 1983 Australian Grand Prix at Calder Park in Melbourne in the Sports Car / GT Challenge support races.
Rusty French won his first Australian GT Championship with a consistent run over the six round series to score 40 points, never finishing outside of the top three positions in any round and winning Round 3 in Adelaide and the sixth and final round at Surfers Paradise. He was also the only driver in the entire field who finished every round of the series. Jim Richards finished second in the championship with 18 points, despite competing in only the first two rounds at Lakeside and Sandown, winning both convincingly, though he was challenged by French at Sandown who used the superior power of his Porsche to stay with the BMW on Sandown's long straights. The 1980 and 1981 Australian Sports Sedan Champion Tony Edmondson finished equal second with Richards in the championship. Like Richards, Edmondson won two rounds with victory at Round 4 at Calder and Round 5 at Winton. Unlike Richards, Edmondson did enter other rounds of the championship. His was one of the cars damaged in the start line crash at the Adelaide round. Alan Browne was classified fourth in the championship in his Porsche 935, scoring 13 points.
As a reward for driving his Porsche 935 to the championship win, French was flown to West Germany in 1984 by Porsche as one of their award winners for 1983. This also secured him a drive with German World Endurance Championship team Kremer Racing at the 1984 24 Hours of Le Mans driving a Porsche 956B. Alongside Englishmen Tiff Needell and David Sutherland, French finished 9th outright in the 24-hour classic.
