The Northern Territory Special Reconnaissance Unit (NTSRU) was an irregular warfare unit of the Australian Army during World War II, composed mainly of Aboriginal people from the Northern Territory. Formed in 1941, the unit patrolled the coast of Arnhem Land during 1942–43 searching for signs of Japanese landings and trained to fight as guerrillas using traditional weapons in the event of an invasion. In 1943, as the war moved northward from the Australian coast, the NTSRU was disbanded.
