1984 Australian Sports Car Championship
The 1984 Australian Sports Car Championship was an Australian motor racing title open to Sports Cars complying with CAMS Group A regulations. It was the 16th Australian Sports Car Championship.
Queensland based owner/driver Bap Romano won the championship driving his Romano WE84 Cosworth. 1982 champion Chris Clearihan,, placed second and Andrew Roberts, driving a self designed Roberts S2 Ford, placed third.
Romano dominated the championship, continuing on from his victory in the final round of the 1983 Championship at Winton. With engineering help from former Williams and Tyrrell Formula One mechanic Wayne Eckersley transforming the Barry Lock built car, Romano put the renamed Romano WE84 on pole position at every round and scored fastest lap in each race which he contested. He was overall winner in each round bar Round 1 at Calder Raceway where he crashed heavily in Heat 1, and was a non-starter in Heat 2. Clearihan scored fastest lap in Heat 2 and was the overall winner of that round.
The expected challenge from Alan Newton in his Elfin MS7-Repco Holden came to a premature end during the first lap of the second heat at the opening round at Calder. Sitting in second behind Clearihan going down Calder's back straight, the cars throttle jammed open going into the braking area and Newton veered left, running at high speed across the infield until hitting a small rise which saw the Elfin literally fly across the track before landing and hitting the guardrail at undiminished speed. Newton survived the crash with nothing more than a busted knee and broken ankle. Although the Elfin suffered heavy damage in the crash, it was later repaired though it took no further part in the championship. Another possible challenger, Terry Hook and his 5.0 litre, ex-Guy Edwards Lola T610 Chevrolet did not contest any races in the championship. Hook's Lola first appeared at Surfers Paradise for Round 2 but Hook became concerned about the car's front end lifting at high speed and the car was not raced. After appearing in practice for the Lakeside round, the car would not appear again until the 1985 Championship.
Romano could have benefited from the fact that his car's 3.0 litre Cosworth DFV engine allowed him to run in Class B which meant he scored more points for a win or place than his main challenger Clearihan did driving in Class C, i.e. a win for Romano meant 28 points while a win for Clearihan scored only 25. As it was, by actually winning 4 of the 5 rounds, and with Clearihan scoring a DNF in Round 3 at Lakeside with damaged suspension, Romano would have still won the championship 100-94 had they both been driving for Class C points.

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 'South Circuit' rather than the full 2.620 km Grand Prix circuit.
