Leyburn airfield was built in early 1942 for use by US heavy bombers, in case the Japanese invaded southeast Queensland. It was maintained by the RAAF but was not used until 1944, by RAAF squadrons flying B-24 Liberator bombers. After the war the circuit formed by the two bitumen runways and the bitumen taxiway linking their north ends was used for motor racing, with an Australian Grand Prix being held at Leyburn in 1949.

The two runways of Leyburn airfield are located over 5km north of Leyburn (northwest of Warwick), between Wirraway Avenue and Elerby Road. Liberator Place, which runs northeast from Wirraway Avenue, follows the route of a former gravelled taxiway to the south end of the 36 degree runway, and then continues along that runway (remnants of the taxiway also continue south of Wirraway Avenue). The 138 degree runway heads northwest from its intersection with the 36 degree runway, and crosses Macquarie Drive and Hamblin Road. A bitumen taxiway then loops northward before heading back across Macquarie Drive to join the northern end of the 36 degree runway, forming a large triangle. No other structures remain on site, but a dam that appeared on wartime maps still exists within the northeast loop of the taxiway.
