2006 Australian Drivers' Championship
The 2006 Australian Drivers' Championship was a CAMS sanctioned national motor racing title open to Formula 3 cars. The title was contested over an eight-round, 16 race series, with the winner being awarded the 2006 CAMS Gold Star. The series was organised and administered by Formula 3 Australia Inc. and was officially known as the "2006 Khumo Tyres Australian Formula 3 Championship for the Australian Drivers' Championship". It is recognised by CAMS as the 50th Australian Drivers' Championship and as the 6th Australian Formula 3 Championship.
British driver Ben Clucas dominated the series driving a Team BRM Dallara F304-Spiess Opel. Clucas won eleven of the twelve races he contested, finishing 52 points ahead of Tim Macrow. Michael Trimble finished third in the points standings, driving a Dallara F304-Renault. Macrow was the only driver to defeat Clucas for a race win before the British driver left the series after Round 6 with an unassailable lead in the points. Macrow also won three of the other four races with Trimble winning the first of the two races held at Queensland Raceway.
