1973 Australian Drivers' Championship
The 1973 Australian Drivers' Championship was a CAMS sanctioned national motor racing title open to drivers of Australian Formula 1 and Australian Formula 2 cars. It was the seventeenth Australian Drivers' Championship and the championship winner was awarded the 1973 CAMS "Gold Star".
The championship was won by John McCormack driving an Elfin MR5 Repco Holden.
Schedule
The championship was contested over a five-round series with one race per round. There was to be a round at Symmons Plains on 23 September in an event shared with the 1973 Australian Formula 2 Championship. However, as just four Formula 5000 cars were entered, organisers decided to run the event only for Formula Two cars. There was also originally to be an event at Warwick Farm before that facility closed suddenly earlier in 1973. As a result of these cancellations, a second event was added at Phillip Island in late November.| Round | Name | Circuit | Date | Winner | Car | Report |
