Note: The Australian Grand Prix was won by New Zealander Graham McRae. However, as the Australian Drivers' Championship was open only to holders of a CAMS General Competition License, 9 points were awarded to the highest placed eligible driver, John McCormack, 6 points to the second highest placed eligible driver etc.
Conditions for the championship were promulgated by CAMS under the name "Australian Formula 1 Championship - Gold Star Award", with mention of the requirement for the phrase “Australian Champion Driver” to be reserved exclusively for the winner of the CAMS Gold Star. Historic records published by CAMS use the term Australian Drivers' Championship  and that title has been used here.
