The 2009 Australian Drivers' Championship was a CAMS sanctioned national motor racing title with the championship winner receiving the 2009 CAMS Gold Star award. The 2009 championship was the 53rd Australian Drivers' Championship and the fifth to be contested with open wheel racing cars constructed in accordance with FIA Formula 3 regulations. The season began on 19 March 2009 at the Adelaide Street Circuit and finished on 29 November at Sandown Raceway after eight events across four different states with two rounds per event. Team BRM driver Joey Foster became the second successive champion from Great Britain, holding off 2007 series champion Tim Macrow by eight points. In the National classes, Tom Tweedie was champion in National A, recording three top-three overall finishes and twelve class wins, while Peter Kalpakiotis was champion in National B as he was the only driver to contest more than one meeting.
Championship points were awarded on a 20-15-12-10-8-6-4-3-2-1 basis to the top ten classified finishers in the Championship Class in each race. One additional point was awarded to the driver setting the fastest lap time in the class in each qualifying session and in each race at each round. The same system was also used for both the National A Class and the National B Class awards.
