The 2012 Australian GT Championship was a CAMS sanctioned national motor racing championship open to GT style closed production based sports cars which were either approved by the FIA for GT3 competition or approved by CAMS as Australian GTs.[1]
It was the 16th Australian GT Championship, the twelfth to be contested over a multi-event championship, and the eighth to be contested since the title was revived in 2005.
The series had a new owner for 2012, with seasoned GT racer Tony Quinn taking over the series towards the end of the 2011 season.
The championship was won by Klark Quinn driving a Porsche 911 GT3-R.
After consolidation from three divisions to two in 2011, the 2012 series saw an expansion to four divisions, based on vehicle eligibility and specification.[1]
