1984 Australian Sports Car Championship

The championship was contested over a five-round series: Round 1 of the championship was originally to be run at Melbourne's Sandown Park. However, due to the circuit's closure while it was rebuilt and lengthened in time for the 1984 Sandown 1000 World Endurance Championship round, the meeting was cancelled. Former racer and millionaire tyre retailer Bob Jane then restored the championship to five rounds by hosting Round 1 at his Calder Park Raceway. Round 4 at Sydney's Oran Park was also cancelled, but was later restored after the circuit owners had a vacant spot to fill in the schedule of support races for the Valvoline 250 Australian Endurance Championship race for Touring Cars. The Oran Park round was contested on the circuits shorter, 1.960 km (1.218 mi) 'South Circuit' rather than the full 2.620 km (1.62 mi) Grand Prix circuit. ==Classes==

Cars competed in three classes according to engine capacity: • Class A : Up to 1.6 litres • Class B : 1.6 to 3 litres • Class C : Over 3 litres ==Points system==

Championship points were awarded as shown in the table below. For Round 1 only, points were awarded for each race with the aggregate achieved by each driver divided by two. The result was the driver's championship points allocation for that round. ==Championship standings==
