Caversham Airfield, also known as Middle Swan Airfield was an airfield constructed at Caversham, Western Australia during World War II as a parent aerodrome for use by the Royal Navy's Fleet Air Arm and the United States Navy.

[3][4] The airfield was later utilised as a motor racing circuit, hosting its first event in 1946.

[5] In 1956 the Western Australia Sporting Car Club gained a lease for the property, which was then converted into a permanent circuit.

[1] It became Western Australia's premier motor racing venue, hosting the Australian Grand Prix in 1957 and 1962[6] and the Six Hour Le Mans endurance race from 1955 to 1968.

[5] Racing activities ceased when the airfield was re-activated as a military facility for radio communications,[6] and Western Australian racing shifted to Wanneroo Raceway in 1969.
