The race was won by Brazilian driver
Roberto Moreno, his third win during the four years in which the Grand Prix was held for the Formula Pacific / Formula Mondial category. While Formula Mondial would continue as the premier Australian open-wheel racing category for another two years, and would not be completely replaced until the creation of
Formula Holden in 1989, this was the last year it would be associated with the Australian Grand Prix, as the race was granted Formula One World Championship status from
1985 and would be contested only by
Formula One cars. In many ways, Australian domestic open-wheel racing would be deprived of a signature race by the arrival of Formula One, a situation that continues as of 2015. The trend of the race organiser
Bob Jane of importing overseas star racers (mostly Formula One drivers) continued. In addition to Moreno, the starters for the 1984 race included , and F1 World Champion
Niki Lauda, F1 World Champion
Keke Rosberg, as well as Formula One drivers
Andrea de Cesaris and
François Hesnault. De Cesaris started from an unguarded pit lane ahead of the field and led the race briefly, although official lap scoring started his race when he started his second lap.
1984 Australian Drivers' Championship winner and front row qualifier,
John Bowe, led the race until lap 9 when overtaken by Moreno after a loose spark plug lead caused his 1.6-litre
Ford engine to misfire. He was forced to pit for a replacement plug lead. Poor starts by Moreno's teammate for the race, Niki Lauda, Rosberg and de Cesaris were overcome as the race progressed. Both keen aviators, Lauda and Rosberg had actually spent most of practice and qualifying attending an air show at the nearby
Essendon Airport, with newly crowned World Champion Lauda stating that he was in Australia mostly for a holiday and just to get away from Europe. Hesnault, Bowe's teammate, retired after a bump with Bruce Connolly. Lauda and Rosberg diced briefly for third, before Rosberg and Terry Ryan clashed when Ryan was being lapped, with the closely following Lauda also colliding with Ryan, the result being that Rosberg and Ryan were able to continue while Lauda was out. Bowe dropped down the field with electrical problems. First Rosberg then de Cesaris caught and overtook the
Tiga FA81/83 of
Alfredo Costanzo to fill the podium positions. Bowe finished sixth behind David McMillan. The
Ralt RT4 was the choice of car for three-quarters of the field, with 18 of the 24 starters driving one. Other cars included Costanzo's
Tiga FA81/83, two
Cheetah Mk.8's, a
Kaditcha FA82A, a Liston BF2 and a Dart 83M. All cars were powered by the
1.6-litre Ford BDA 4 cylinder engine. Touring car driver Peter Williamson was entered in a
Toyota powered
Toleman TG860, but a crash in early practice that damaged the car saw him announce his retirement from open wheel racing. Consequently, the Toleman was withdrawn from the meeting. Due largely to the Australian Grand Prix becoming a round of the
Formula One World Championship from 1985, John Bowe became the last Australian driver to lead an AGP until
Mark Webber led lap 21 of the
2006 Australian Grand Prix in a
Williams FW28-
Cosworth. With Moreno taking the lead from Bowe on lap 9 of the race, it would be a total of 1,504 race laps before Webber would next put an Australian in the lead of an Australian Grand Prix. == Classification ==
