1972 Hardie-Ferodo 500

Brock finished a lap ahead of Queensland racer John French driving a Ford XY Falcon GT-HO Phase III, this despite Brock being penalised one minute at his last pit stop for starting his car while the HDT crew were still re-fueling (under the ARDC's race regulations of the day, car engines had to be switched off during pit stops and could only be restarted once the re-fueling had been completed).

After contesting the lead with Brock in the early laps, Moffat spun his factory entered Ford Falcon at Sulman Park on top of The Mountain in the wet conditions.

1967 winner Fred Gibson also rolled his Works GTHO Falcon at McPhillamy Park in the early wet conditions after being forced offline when lapping a slower car.

The 3001 to 9000 CP units class saw a mix of Datsun 1600, Fiat 124 Sport, Ford Escort, 2.8 litre Holden Torana and Mazda RX-2.

The 9001 to 18000 CP units class featured Alfa Romeo 1750 GTV, E38 version of the Chrysler Valiant Charger and 3.3 litre Holden Torana GTR XU-1.
