The 2005 Supercheap Auto Bathurst 1000 was the ninth running of the Australia 1000 race, first held after the organisational split over the Bathurst 1000 that occurred in 1997. It was the 43rd anniversary of the original touring car endurance race held at the Mount Panorama Circuit in 1963. It was the 49th race that traces its lineage back to the 1960 Armstrong 500 held at Phillip Island.
