The First Australian Army was a field army of the Australian Army, during World War II. The formation's headquarters was raised in April 1942 from the existing 1st Australian Corps headquarters, assuming command of all Allied troops in Queensland. Initially, the formation was assigned a defensive role in anticipation of a possible Japanese invasion; however, this threat subsided and eventually the army was deployed to Lae, in New Guinea, in late 1944, where it co-ordinated Australian offensives around Aitape, in New Guinea, on New Britain and Bougainville, and around Madang. The formation was disbanded in February 1946, when it was redesignated as the 8th Military District.
III Corps was an Australian Army unit during World War II. It was responsible for the defence of Western Australia in 1942–1944. The corps was formed in April 1942 from Western Command, which had been established in October 1939. Throughout the war, the formation's size expanded and contracted as available manpower, and the strategic situation, dictated. At its height, the corps consisted of two infantry divisions and one armoured division, which were deployed to defend against a Japanese invasion threat, which ultimately never eventuated. The corps ceased to exist in June 1944 when it was converted back into Western Command, which remained until the end of the war in 1945.
The 2nd Armoured Division was an armoured formation of the Australian Army during World War II. Originally raised in 1921 as the 2nd Cavalry Division, based in Victoria and South Australia, the formation had been converted into a motor division in early 1942, before adopting the armoured designation later in the year. A Militia formation, the division undertook garrison duties in Australia and did not see combat before being disbanded in mid-1943.
The 3rd Brigade is a combined arms brigade of the Australian Army, principally made up of the 1st and 3rd Battalions of the Royal Australian Regiment. Initially raised in 1903 as part of the post-Federation Australian Army, it was removed from the order of battle in 1906 following the restructure of the field force. It was re-formed in 1914 for service during World War I, taking part in the fighting at Gallipoli and on the Western Front in Europe. During World War II the brigade was used in a defensive role before it was disbanded in 1944. It was re-raised in 1967 for service during the Vietnam War and later went on to provide the nucleus of the deployment to East Timor during the Australian-led intervention in 1999. The brigade is currently based at Lavarack Barracks in Townsville, Queensland.
The 16th Brigade was an infantry brigade in the Australian Army. First raised in 1912 as a Militia formation to provide training under the compulsory training scheme, the brigade was later re-raised as part of the First Australian Imperial Force during World War I. Its existence was short-lived, as it was disbanded after about six months, before it could be committed to the fighting on the Western Front. Raised again in 1939 for service during World War II, the brigade was deployed to the Middle East in early 1940 and subsequently saw action in the Western Desert and in Greece in 1941. In 1942, it returned to Australia in response to Japan's entry into the war, and later the brigade played a prominent role in the Kokoda Track campaign and at Buna–Gona in Papua. Withdrawn to Australia in early 1943, the 16th Brigade was re-organised and received many replacements from disbanding formations, but it was not recommitted to combat operations until late in the war. In 1944–1945, the brigade was committed to the Aitape–Wewak campaign in New Guinea. After the war, the brigade was disbanded in 1946. Today, its name is perpetuated by the 16th Aviation Brigade which was raised on 2 April 2002.
I Corps was an Australian Army corps, one of three that were raised by the Army during World War II. It was the main Australian operational corps for much of the war. Various Australian and other Allied divisions came under its control at different times.

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 2/4th Armoured Regiment was an armoured regiment of the Australian Army, which served during World War II. The regiment was formed in November 1942 as part of the Second Australian Imperial Force by amalgamating a number of previously existing armoured units and was disbanded in September 1946 after seeing action in New Guinea and Bougainville Island, where it provided individual squadron-group sized elements which operated in support of infantry operations against the Japanese. During its service the regiment received 10 battle honours.
The 2/12th Field Ambulance was an Australian military unit of the Second Australian Imperial Force, serving during World War II. During their six years of service, over 200 soldiers were killed, the highest figure for a non-combatant unit in Australian history. The majority of the unit's casualties were suffered during the sinking of the hospital ship Centaur in May 1943. During the war, the 2/12th deployed personnel in support of Australian combat operations against the Japanese on Ambon, Timor and in Borneo before being disbanded in 1946.

The structure of the Australian Army changed considerably during World War II. At the outbreak of war the Army comprised a small regular component and a large, but ill-trained and equipped, militia force. In September 1939 the government authorised the establishment of the Second Australian Imperial Force for overseas service; this force eventually reached a strength of four infantry divisions, an armoured division and various headquarters and support units. The militia force, which remained in Australia, was neglected until the outbreak of the Pacific War.
