The Lowood Airfield Circuit was a motor racing venue in Queensland, Australia which was used from 1946 to 1966. It was located at a former wartime airfield site at Mount Tarampa, near Lowood, 72 km west of the state capital Brisbane. The circuit utilised the airfield’s runway for its 1.9 km long 200 metre wide main straight and also used various taxiways and tarmac from the old hangar area.
