The FCS was located on Fraser Island in Southeast Queensland, near to the McKenzies Jetty, just south of what is now the Kingfisher Bay Resort. The site was selected due to its seclusion and sparse habitation. At the time of the establishment of the FCS, Fraser Island was virtually uninhabited apart from a small Forestry establishment at Central Station and a Royal Australian Air Force Radar Station at Sandy Cape, on the northern tip of the island. Fraser Island also has rainforest areas which were utilised for jungle warfare training and a series of freshwater lakes. The largest of these, Lake McKenzie, was used for parachute water jump training by night and day.
