The 2003 Australian Drivers' Championship was a CAMS sanctioned national motor racing title for drivers of cars conforming to Formula 4000 regulations.[1] The title was contested over a six-round, twelve race series which was promoted as the 2003 Holden Australian Drivers' Championship for the CAMS Gold Star.[1] It was the 47th Australian Drivers' Championship.[2]
New Zealander Daniel Gaunt won the championship[2] driving three different Reynards for two different teams over the course of the season. Gaunt only won two of the twelve races but achieved a race finishing consistency his rivals lacked and finished eight points ahead of his nearest rivals. Second place was tied between Jonny Reid and Paul Trengove,[3] both driving Reynards.
Apart from the seven wins claimed by Gaunt and Reid, three wins were taken by another New Zealander, Nelson Hartley (Reynard 94D & Reynard 97D), and two wins by Ricky Occhipinti (Reynard 97D and 98D).
