Port Wakefield Circuit was a motor racing circuit located approximately 1 kilometre (0.62 mi) east of the town of Port Wakefield in South Australia. It was the first purpose built motor racing facility built in Australia after World War II, and only the second in Australian history. The circuit was created out of necessity in 1953 when two years prior the South Australian state government banned motor racing on public roads, a ban that would stay in place until 1985 when it was rescinded to create the Adelaide Street Circuit for use in the Australian Grand Prix which had become a round of the Formula One World Championship.
