2005 Australian GT Championship

The 2005 Australian GT Championship was an Australian motor racing competition for "closed production based sports cars". It was sanctioned by the Confederation of Australian Motor Sport as a "National Championship".
It was the ninth Australian GT Championship and the first to be held since 1985. CAMS revived the GT Championship after the demise of the Australian Nations Cup Championship at the end of 2004.
The championship was won by Bryce Washington driving a Porsche 911 GT3 Cup.
