Australian Formula Pacific 1983
After starting so well in 1982 with good grids, Formula Pacific slipped back significantly in 1983, due in large part to the FIA's decision to launch a FIA World Cup for "Formula Mondial", a new formula based closely on Formula Atlantic and Formula Pacific and designed to replace both. The changes from Pacific to Mondial were not trivial, standardising the engine on the Cosworth BDA, banning skirts and some minor chassis changes, but it was enough to make some people wary of entering the category. A South Pacific Zone championship was held in New Zealand and Australia in January and February, won by Charlie O'Brien, but interest was very low, and CAMS decided to stick with Formula Pacific rules for the national championship in 1983, and move to Mondial in 1984.
Current champion Alfredo Costanzo retained his 1981 Tiga, and main contenders John Smith, Andrew Miedecke and John Bowe all retained their 1981 Ralts, but the most interesting additions to the field were the locally built Cheetah Mk8s of ANF3 and ANF2 stalwarts Brian Sampson and Peter Macrow. After Costanzo quickly wrapped up his fourth consecutive national title, the Gold Star round at Winton in October attracted only seven Formula Pacifics, plus six ANF2 cars, mostly Cheetahs, to make up the grid.
The Grand Prix was another success, with 11 Internationals and a total of 24 cars on the grid. The talented Roberto Moreno won again, with John Smith holding off Jacques Laffite to take an impressive second place.
