During World War II more than 900 men gathered on the western side of Fraser Island to complete a series of top secret, high-level training missions for the Australian Army.
The men, who became known as the Z Special Unit, trained in the island's bush, beaches and sub-tropical rainforests and essentially formed part of Australia's first Special Forces.
Known only to the Prime Minister and High Command, the Z Unit completed more than 260 operations behind enemy lines during the war.
Secrecy has surrounded the Z Unit for decades - even after the war - but today, guests at Kingfisher Bay Resort can learn first-hand about one of the most mysterious and successful chapters of Australia's military history with a three-hour guided tour of the Z Commando School site.
