Classes

As the race was an Australian Manufacturers’ Championship round, the field was divided into five classes, based on “CP Units”. The engine capacity, in litres, was multiplied by the retail price, in Australian Dollars, to arrive at a CP Unit value for each competing model.
The winner's race time for the 100 lap, 225 mile race was 3 hours 6 minutes 29.5 seconds.
From the 30 entries for the race, 28 cars started, with seven failing to finish.
