The Australian Formula 2 category was established by the Confederation of Australian Motor Sport (CAMS) in 1964 as the third tier of single seater motor racing in Australia, below the Australian National Formula and the Australian 1½ Litre Formula and above Australian Formula 3. It was a two part formula consisting of (a) cars using production based engines of up to 1100cc capacity (the discontinued Formula Junior class from 1963) and (b) cars using free design four cylinder engines of up to 1000cc capacity (the then current FIA Formula Two class). A single race Australian Formula 2 Championship was instituted in 1964 however the title was discontinued after two years.
