It was the 56th year of touring car racing in Australia since the first runnings of the Australian Touring Car Championship, now known as the International V8 Supercars Championship, and the fore-runner of the present day Bathurst 1000, the Armstrong 500.
There was also a stand-alone event supporting the 2015 Australian Grand Prix.
The season also featured the sixteenth second-tier Dunlop V8 Supercar Series, contested over seven rounds.
The series championships were won by Mark Winterbottom (V8 Supercar Championship), Cameron Waters (Dunlop Series) and Liam McAdam (Kumho KVTC) respectively.
