The 1982 Australian GT Championship was a CAMS sanctioned Australian motor racing title open to Group D GT cars and Group B Sports Sedans. It was the fifth Australian GT Championship, the first to be awarded since 1963 and the first to be contested over a series of races rather than a single race. The 1982 title, which was contested over a nine round series from 16 May to 10 October, was won by Alan Jones driving a Porsche 935/80 entered by Porsche Cars Australia.
With a number of GT cars appearing on the scene such as the Porsche 935 and Porsche 944, as well as the IMSA GT style Chevrolet Monza (which had already been racing in Sports Sedans since Allan Moffat first drove one to win the 1976 Australian Sports Sedan Championship), CAMS made the decision to discontinue the Australian Sports Sedan Championship at the end of 1981 and revive the GT Championship name.
The championship was dominated by 1980 Formula One World Drivers' Champion Alan Jones who went through the season undefeated. His closest on-track rival was multiple Bathurst winner and Australian Touring Car Champion Peter Brock, driving a Bob Jane owned 6.0L V8 Chevrolet Monza. Brock placed fifth in the championship, having contested four of the nine rounds. Brock and the Monza were often faster in qualifying than the turbocharged Porsche. However, the Bathurst legend was rarely able to maintain his tyres for the entire race duration and subsequently always finished second best. Although Alan Jones won every round, his battles with Peter Brock are regarded by those who witnessed it as some of the closest and best racing seen to that point in Australian motor racing history.
