The 2004 Bob Jane T-Marts 1000 was a motor race for V8 Supercars, staged on 10 October 2004 at the Mount Panorama Circuit just outside Bathurst in New South Wales, Australia.

The event was the eighth Australia 1000, first held after the organisational split over the Bathurst 1000 that occurred in 1997.

The 2004 event was the 47th race with a lineage back to the 1960 Armstrong 500 held at Phillip Island.

The 2004 event was the 32nd and last Bathurst 500/1000 for nine time race winner Peter Brock.

Amongst the debutants were former Formula One driver Alex Yoong, future championship race winners Fabian Coulthard and Lee Holdsworth and future New Zealand Touring Cars champion John McIntyre.
