Several training schools were established in various locations across Australia, the most notable being Camp Z in Refuge Bay, an offshoot of Broken Bay to the north of Sydney, Z Experimental Station (also known as the "House on the Hill" or ZES.) near Cairns, Queensland, Fraser Commando School (or FCS) on Fraser Island, Queensland where a commemorative monument stands on the mainland overlooking the island. As a training exercise, one group led by Samuel Warren Carey paddled folboats between Fraser Island and Cairns. Another training school was the Special Boat Section at Careening Bay Camp, on Garden Island, Western Australia. Another, in Darwin on the site of the Quarantine Station, was named the Lugger Maintenance Section to disguise its true purpose.
