The name commando has been applied to a variety of Australian special forces and light infantry units that have been formed since 1941–42. The first Australian "commando" units were formed during the Second World War, where they mainly performed reconnaissance and long-range patrol roles during Australia's campaigns in New Guinea and Borneo, although other units such as M and Z Special Units performed more clandestine roles. These units were disbanded following the end of the war; however, in the 1950s it was realised that there was a need for such units again in the Australian forces. Today, the Australian Army possesses a number of units that perform more conventional direct-action type commando roles, as well as counter-terrorism response, long-range patrolling, and clandestine deep-penetration operations.

The Allied Translator and Interpreter Section (ATIS), also known as the Allied Translator and Interpreter Service or Allied Translator and Intelligence Service, was a joint Australian/American World War II intelligence agency which served as a centralized allied intelligence unit for the translation of intercepted Japanese communications, interrogations and negotiations in the Pacific Theater of Operations between September 1942 – December 1945.

Fighting the guerrillas – apart from the Japanese regular forces – were a Japanese-formed Bureau of Constabulary, the Kenpeitai, and the Makapili. Postwar studies estimate that around 260,000 people were organized under guerrilla groups and that members of anti-Japanese underground organizations were more numerous. Such was their effectiveness that by the end of World War II, Japan controlled only twelve of the forty-eight provinces.

Operation Semut was a series of reconnaissance operations carried out by Australia's Z Special Unit in 1945, during the final stages of World War II.

Another closely related operation codenamed Agas was carried out concurrently in North Borneo. Both operations combined and relayed their intelligence through the Stallion Project to Australian forces and carried out guerrilla warfare against the Japanese in the region with the full support of the local population. A total of four operations were undertaken under the auspices of Operation Semut, concluding in September and October 1945.
