Hoxton Park Airport (YHOX) was a general aviation aerodrome in south-western Sydney.
The aerodrome was constructed by the Royal Australian Air Force (RAAF) in 1942-43 as one of many groups of airfields to be used as aircraft dispersal fields just in case the event of Japanese air attack on the Sydney should occur.
Aircraft revetment hideouts were constructed within adjacent vegetation to hide and disperse aircraft.
The aerodrome was used as an emergency and training field and satellite field for Schofields, Bankstown and Camden during World War II by the RAAF.
The original airstrip was 5000 ft (1524m) long and 172 ft (52m) wide.
Several aircraft revetments that existed in the farmland to the west of the aerodrome may have been removed (possibly destroyed during the construction of the M7 motorway).
The development of Western Sydney finally caught up with the aerodrome. The runway was dug up and permanently destroyed.
The land is now a major distribution center for the Sydney area, with a nice monument explaining the significance of the site that was built ‘Just in case’
