2nd New Guinea Infantry Battalion

The 2nd New Guinea Infantry Battalion (2NGIB) was a battalion of the Australian Army formed in 26 September 1944 in the territory of New Guinea, during World War II, in order to fight against the Japanese. Its soldiers were primarily natives of New Guinea, under the command of Australian officers and NCOs. Formed late in the war the battalion ultimately played a minor role during the allied campaigns in New Guinea, but did see service during the Aitape–Wewak campaign. 2NGIB had an establishment of about 77 Europeans and 550 native soldiers.

The Papuan Infantry Battalion (PIB) along with the 1st and 2nd New Guinea Infantry Battalion were amalgamated to form the Pacific Islands Regiment in November 1944. The 3rd and 4th New Guinea Infantry Battalion joined the regiment in 1945, although 4NGIB was soon disbanded, whilst the 5th New Guinea Infantry Battalion—although authorised—was never raised. The battalion was disbanded in June 1946.
