Motor racing competition
From Wikipedia, the free encyclopedia
The 1983 Australian Drivers' Championship was a CAMS sanctioned motor racing title open to drivers of Australian Formula 1 racing cars.[1] The winner of the title, which was the 27th Australian Drivers' Championship,[2] was awarded the 1983 CAMS Gold Star.[1]
Italian born, Melbourne based driver Alfredo Costanzo won his fourth straight CAMS Gold Star driving his Tiga FA81 Ford. John Smith finished second in his Ralt RT4, including being the first Australian driver home in the final round of the championship, the Australian Grand Prix held at Melbourne's Calder Park. Port Macquarie privateer Andrew Miedecke drove his RT4 to 3rd in the championship despite only deciding to race after watching Costanzo win the first round of the series in Adelaide on television.
