The 2009 Australian Drivers' Championship was a CAMS sanctioned national motor racing title with the championship winner receiving the 2009 CAMS Gold Star award.
Team BRM driver Joey Foster became the second successive champion from Great Britain, holding off 2007 series champion Tim Macrow by eight points.
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.
Originally Event 7 of the series was to have taken place at Symmons Plains Raceway in Tasmania, and was indeed set to host the series signature race, the Tasmanian Super Prix on 18 October, however with several other series involved in the Shannons Nationals Motor Racing Championships withdrawing from the logistically difficult Tasmanian meeting, the event was cancelled.
Subsequently, a new meeting was organised to be held at Queensland Raceway on 21 August on the support card of the V8 Supercar Championship Series.
