Establishment and Training of Independent Companies
1941:
Royal Australian Navy (RAN) intelligence officers were appointed to supervise the civil servants, plantation managers and missionaries in the islands to the north of Australia, who had been organized prior to the outbreak of war, to provide intelligence and coast watching information should their islands be occupied by the enemy.
Concurrently, the Australian Army, acting on British advice had begun to train Independent Companies whose role would include raids, demolitions, sabotage, subversion and organizing civil resistance, as these activities would be carried out by SOE in Europe. Initially it was planned to send the first trained Independent Companies to the Middle East, however, perhaps anticipating a Japanese advance, it was decided to use them in the islands to the north and north-east of Australia to warn of the approach of Japanese forces and to remain behind and harass the invaders.
British SOE Officers Arrive in Australia
March 1942:
Two British SOE officers arrived in Australia after service in Singapore and Java to assist in establishing a SOE organization, which supported by General Thomas Blamey, Commander in Chief of the Australian Military Forces, had the approval of the Prime Minister of Australia, John Curtin.
In May 1942 a new special operations organization, the Inter-allied Services Department (ISD) was set up in Melbourne under General Blamey's control.
