Caversham Grand Prix Track / RAAF Caversham

Caversham Airfield, also known as Middle Swan Airfield, was an airfield constructed at Caversham, Western Australia during World War II. It was the only parent aerodrome constructed for the U.S. Fleet Air Arm in this State during this period, with only two others constructed in Australia, and is one of only a small number of all-weather aerodromes with three or more intersecting runways constructed in Australia in the 20th century.

The place is the only World War Two aerodrome known to have been utilised as a car racing circuit in the post-war period and played a very significant role in the development and growth of car racing in this State in the post-war period.

Caversham Motor Racing Circuit became Western Australia's premier motor racing venue. Caversham was particularly notable as the venue for the Victory Grand Prix in 1946, the first such even held outside Western Europe and the first in Australia after World War Two. The Circuit was then used for the Six-Hour Le Mans endurance races from 1955 to 1968; and the Australian Grand Prix in 1957 and 1962.

The airfield was also an integral part of the development and growth of gliding in this State from 1946 to 1961.

The site demonstrates the skills and achievements of Main Roads (WA) in road making as applied to aerodrome construction during WWII and is valued by the community for social and cultural reasons, including those in the wider community who recollect the Caversham Raceway period.

Its remaining material, including runways, aerial mast stays block bases, signal buildings, and racing circuit and associated remnant structures all contribute to an understanding of the physical requirements of a Fleet Air Arm aerodrome, and subsequent uses such as a racing circuit and lastly a RAAF Signal Station.
