II Corps was an Australian Army corps, one of three that were raised by the Army during the Second World War. Formed in mid-1942 as part of defensive measures to protect the eastern coast of Australia from invasion, the corps was initially composed mainly of home defence troops drawn from the Militia. For a brief period in 1942, a US infantry division was also assigned to the corps prior to its dispatch to fight the Japanese in New Guinea.
The 2/2nd Battalion was an infantry battalion of the Australian Army raised for service as part of the all-volunteer Second Australian Imperial Force during World War II. Raised in October 1939, the battalion was deployed to the Middle East and in early 1941 took part in the first ground action undertaken by Australian troops during the war during the Battle of Bardia before helping to capture Tobruk. In April, the battalion briefly fought in Greece, before being evacuated after the Allied forces were overwhelmed by German forces. Some members of the battalion took part in the Battle of Crete, after which the battalion undertook garrison duties in Syria. In mid-1942, the 2/2nd undertook defensive duties in Ceylon before returning to Australia. They subsequently took part in the fighting against the Japanese along the Kokoda Track and then around Buna–Gona. After a period of reorganisation and training in Australia throughout 1943–44, late in the war the battalion was committed to the Aitape–Wewak campaign before being disbanded in early 1946 after the war.
The 2/5th Battalion was an infantry battalion of the Australian Army that operated during World War II. It was raised at Melbourne, Victoria, on 18 October 1939 as part of the Second Australian Imperial Force, attached to the 17th Brigade of the 6th Division. The 2/5th was one of only two Australian infantry battalions to fight against all of the major Axis powers during the war, seeing action against the Germans and Italians in Egypt, Libya, Greece and Crete, and the Vichy French in Syria, before returning to Australia in 1942 to fight the Japanese following a period of garrison duties in Ceylon, where it formed part of an Australian force established to defend against a possible Japanese invasion.
The 2/7th Battalion was an infantry battalion of the Australian Army raised for service during World War II. Formed as part of the 6th Division shortly after the outbreak of the war as part of the all-volunteer Second Australian Imperial Force, the 2/7th Battalion's initial personnel were recruited primarily from the state of Victoria, although later reinforcements were drawn from most other Australian states. Basic training was completed in Australia, after which the battalion embarked for the Middle East as part of the first batch of Australian troops to deploy overseas. Further training was undertaken in Palestine before the battalion went into action against the Italians in January 1941. After participating in the successful capture of Bardia and Tobruk, it was committed to the disastrous Battles of Greece and Crete, where the battalion was essentially destroyed after the majority of its personnel were captured.
The Huon Peninsula campaign was a series of battles fought in north-eastern Papua New Guinea in 1943–1944 during the Second World War. The campaign formed the initial part of an offensive that the Allies launched in the Pacific in late 1943 and resulted in the Japanese being pushed north from Lae to Sio on the northern coast of New Guinea over the course of a four-month period. For the Australians, a significant advantage was gained through the technological edge that Allied industry had achieved over the Japanese by this phase of the war, while the Japanese were hampered by a lack of supplies and reinforcements due to Allied interdiction efforts at sea and in the air.
The 2/16th Battalion was an infantry battalion of the Australian Army, serving during World War II. Attached to the 21st Brigade that was assigned to the 7th Division, the 2/16th was raised in 1940 as part of the Second Australian Imperial Force from volunteers drawn mainly from the state of Western Australia. After training in Australia, the battalion was deployed to the Middle East where it undertook defensive duties along the Egyptian–Libyan border in early 1941 before taking part in the Syria–Lebanon campaign, fighting against Vichy French forces in June and July. At the conclusion of the campaign, the 2/16th remained in Lebanon, contributing to the Allied occupation force there, before returning to Australia in early 1942 following Japan's entry into the war. In August 1942, they were committed to the fighting along the Kokoda Track and then later fought around Buna and Gona. After a period of rest and reorganisation in Australia, the battalion fought around Lae and then took part in the Finisterre Range campaign in 1943–44. Its final campaign of the war came in Borneo in July 1945. At the end of the war, the 2/16th were disbanded in January 1946.
The Landing at Lae was an amphibious landing to the east of Lae and then the subsequent advance on the town during the Salamaua–Lae campaign of World War II. Part of Operation Postern, which was undertaken to capture the Japanese base at Lae, the landing was undertaken between 4 and 6 September 1943 by Australian troops from the 9th Division, supported by US naval forces from the VII Amphibious Force. The first major amphibious operation undertaken by the Australian Army since the failed Gallipoli Campaign, the Australians invested a significant amount of effort into planning the operation.

In mid-1945, the brigade was committed to the Bougainville campaign, before being disbanded following the end of hostilities.
The 29th/46th Battalion was an infantry battalion of the Australian Army. It was formed in August 1942 by the amalgamation of two previously existing Militia battalions, the 29th and 46th, which were merged following a decision by the Australian government to release manpower from the military back into industry to meet the nation's increased production requirements. Initially the 29th/46th, serving as part of the 4th Brigade, undertook garrison duties in Australia, however, in 1943 the battalion was deployed to New Guinea where it garrisoned Milne Bay before subsequently taking part in the Huon Peninsula campaign in support of the 9th Division. In late 1944, after being deployed for over a year and a half, the battalion returned to Australia for a brief period of leave and reorganisation. In early 1945, however, they were again deployed overseas, this time to the island of New Britain where they undertook a campaign to contain the large Japanese garrison. Following the end of the war the battalion was disbanded in June 1946.

In 1937, the battalion was briefly re-raised in its own right before being amalgamated with the 39th Battalion. It later returned to the order of battle in its own right as the Australian military was expanded due to concerns of a future war in Europe. Following the outbreak of World War II, the 37th Battalion served in a garrison role until 1942 when it was once again amalgamated with the 52nd Battalion.
The Battle of Wareo was fought by Australian and Japanese forces in New Guinea during the Huon Peninsula campaign of World War II in the later part of 1943. Coming after the capture of Sattelberg by the Allies, the battle took place amidst the Australian advance north towards Sio.
