The 1984 Australian Drivers' Championship was a CAMS sanctioned national motor racing title open to drivers of racing cars complying with Formula Mondial regulations.[1]
The winner of the title, which was the 28th Australian Drivers' Championship, was awarded the 1984 CAMS Gold Star. John Bowe won the championship driving a Ralt RT4 Ford. It would be the first of two such titles for the Tasmanian driver. Finishing second in the championship was four-time defending champion Alfredo Costanzo in his Porsche Cars Australia team Tiga FA81 Ford, while the 1983 Australian Sports Car Champion Peter Hopwood driving his Ralt RT4 Ford finished in third place in his first full season of open wheel racing.
After finishing 4th and being the first resident Australian driver home in the non-championship 1984 Australian Grand Prix at Melbourne's Calder Park Raceway in November, Alfie Costanzo effectively retired from open wheel racing when his Porsche Cars Australia team boss Alan Hamilton closed the race team.
