An airfield with a 7,000-foot runway was constructed by April 1943 for the use of the United States Army Air Force.[6] The airfield was eventually used by 21 Squadron, 23 Squadron and 99 Squadron.[6] and was eventually abandoned by the RAAF in December 1945.[6] The abandoned airfield became the site of the 1949 Australian Grand Prix, the first time the Australian Grand Prix was held in Queensland.
