The 6th Division was an infantry division of the Australian Army. It was raised briefly in 1917 during World War I, but was broken up to provide reinforcements before seeing action. It was not re-raised until the outbreak of World War II, when it was formed as a unit of the Second Australian Imperial Force. Throughout 1940–41 it served in the North African Campaign, the Greek campaign, on Crete and in Syria, fighting against the Germans, Italians and Vichy French. In 1942, the division left the Middle East and returned to Australia to meet the threat of Japan's entry into the war. Part of the division garrisoned Ceylon for a short period of time, before the division was committed to the New Guinea campaign. In New Guinea, its component brigades had a major role in the successful counter-offensive along the Kokoda Track, at Buna–Gona and around Salamaua–Lae in 1942–43. Throughout late 1943–44, the division was re-organised in Australia before being committed as a complete formation to one of the last Australian operations of the war around Aitape–Wewak in 1944–45.
The 2/6th Battalion was an infantry battalion of the Australian Army that served during the Second World War. Raised in October 1939 as part of the all volunteer Second Australian Imperial Force, the battalion formed part of the 6th Division and was among the first troops raised by Australia during the war. Departing Australia in early 1940, the 2/6th were deployed to the Middle East where in January 1941, it took part in the first action of the war by Australian ground forces, the Battle of Bardia, which was followed by further actions around Tobruk. Later, the 2/6th were dispatched to take part in the Battle of Greece, although their involvement in the campaign was short before they were evacuated. Some members of the battalion also subsequently fought on Crete with a composite 17th Brigade battalion, and afterwards the battalion had to be re-formed in Palestine before being sent to Syria in 1941–42, where they formed part of the Allied occupation force that was established there in the aftermath of the Syria–Lebanon campaign.
The 25th Battalion was an infantry unit of the Australian Army. Raised in early 1915 as part of the Australian Imperial Force during the First World War, the battalion fought at Gallipoli and in the trenches along the Western Front, before being disbanded in early 1919. In mid-1921, it was re-formed as a part-time unit based in the state of Queensland. Throughout the 1930s, the battalion was merged briefly with the 49th Battalion as a result of manpower shortages, but was later re-raised in its own right. During the Second World War, the 25th deployed to New Guinea where they fought the Battle of Milne Bay in August and September 1942. Later in the war, the 25th took part in the Bougainville Campaign. During the post-war period, the 25th Battalion became part of the Royal Queensland Regiment, variously forming battalion or company-sized elements, before being merged with the 49th Battalion to form the 25th/49th Battalion, Royal Queensland Regiment.
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 36th Battalion was an infantry battalion of the Australian Army. It was originally raised in 1916 as part of the First Australian Imperial Force during World War I. Throughout World War I the battalion served on the Western Front as part of the 9th Brigade, attached to the 3rd Division. Due to heavy casualties amongst the AIF and a decrease in the number of replacements arriving from Australia in 1918, the battalion was disbanded before the war ended in order to reinforce other units in France. The 36th Battalion was re-raised in 1921 as part of the Militia based in Sydney. During World War II the battalion was attached to the 14th Brigade and was initially used in a defensive role as a garrison unit in Australia before being sent to New Guinea in 1942. Throughout the course of the war in the Pacific, the 36th Battalion spent most of the 1942–45 period overseas in New Guinea and New Britain where they undertook operations against the Japanese. In June 1945 they were returned to Australia and shortly afterwards the battalion was disbanded.
The 17th 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. Established in 1917 in the United Kingdom, it was broken up and disbanded without seeing action, and its personnel used as reinforcements for other formations. Reformed during World War II, it took part in fighting in Libya, Greece, Crete, Syria in 1941–1942. Following Japan's entry into the war, the Australian government pressed for the 6th Division's return, and the 17th Brigade was subsequently brought back from the Middle East, via Ceylon where they undertook defensive duties until July 1942. Following the brigade's return to Australia, it was deployed to New Guinea for two campaigns: the Salamaua–Lae campaign in 1943 and the Aitape–Wewak campaign in 1944–1945. After the war, the brigade was disbanded in January 1946. Today, its name is perpetuated by the 17th Sustainment Brigade, which was raised as a logistics formation in May 2006.
The 39th Battalion was an infantry unit of the Australian Army. It was originally raised in February 1916 for service during World War I as part of First Australian Imperial Force, with personnel being drawn mainly from the state of Victoria. Making up part of the 10th Brigade, it was attached to the 3rd Division and served on the Western Front in France and Belgium before being disbanded in March 1919. Following the re-organisation of the Australian Army in 1921, the battalion was raised again in Victoria as a unit of the Citizens Force, becoming known as the "Hawthorn–Kew Regiment". In 1937, it was amalgamated with the 37th Battalion to become the 37th/39th Battalion. Later, in August 1939 it was delinked with the 37th and amalgamated with the 24th Battalion to form the 24th/39th Battalion, before being raised again as a single unit in October 1941.
The New Guinea Volunteer Rifles (NGVR) was an infantry battalion of the Australian Army. It was initially raised as a unit of the Militia from white Australian and European expatriates in New Guinea upon the outbreak of the Second World War in 1939, before being activated for full-time service following the Japanese landings in early 1942. NGVR personnel then helped rescue survivors of Lark Force from Rabaul in February and March 1942. Between March and May, the NGVR monitored the Japanese bases which had been established in the Huon Gulf region, being the only Allied force in the area until the arrival of Kanga Force at Wau in May. The battalion subsequently established observation posts overlooking the main approaches and reported on Japanese movements.
New Guinea Force was a military command unit for Australian, United States and native troops from the Territories of Papua and New Guinea serving in the New Guinea campaign during World War II. Formed in April 1942, when the Australian First Army was formed from the Australian I Corps after it returned from the Middle East, it was responsible for planning and directing all operations within the territory up until October 1944. General Headquarters Southwest Pacific Area Operational Instruction No.7 of 25 May 1942, issued by Commander-Allied-Forces, General Douglas MacArthur, placed all Australian and US Army, Air Force and Navy Forces in the Port Moresby Area under the control of New Guinea Force. Over the course of its existence, New Guinea Force was commanded by some of the Australian Army's most notable commanders, including Sydney Rowell, Sir Edmund Herring and Sir Leslie Morshead.
The 18th Brigade was an infantry brigade of the Australian Army. The brigade briefly existed as a Militia formation prior to the First World War, but this was short lived. During the Second World War, the brigade was raised on 13 October 1939 and was one of the first three infantry brigades of the Second Australian Imperial Force to be formed. Initially commanded by Brigadier Leslie Morshead, it served in the United Kingdom in 1940–1941, where it helped bolster the British garrison in anticipation of a possible German invasion following the Fall of France. In early 1941, the brigade was transferred to the Middle East where it later took part in fighting against the Italians in Libya and then helped to defend the besieged port of Tobruk before fighting against the Vichy French in the Syria–Lebanon campaign. The 18th Brigade was withdrawn to Australia in early 1942, and it later took part in the fighting against the Japanese in Pacific fighting several campaigns in New Guinea between late 1942 and early 1944. Its final involvement of the war came in mid-1945 when it took part in re-taking Balikpapan. Following the end of hostilities, the 18th Brigade was disbanded on 3 January 1946.
The 11th Division was an Australian Army unit formed during World War II by the renaming of Milne Force in December 1942. Predominately a Militia formation, the division's main role during the war was as a base command headquarters, although elements saw action in New Guinea against Japanese forces during the Finisterre Range campaign and in New Britain. It was disbanded in July 1946.
The 53rd Battalion was an infantry battalion of the Australian Army. Raised in 1916 for service during World War I the battalion served on the Western Front until the end of the war, before being briefly amalgamated with the 55th Battalion and then eventually disbanded in 1919. In 1921, the 53rd Battalion was re-raised and in 1927 adopted the title of the "West Sydney Regiment"; however, in 1937 they were once again amalgamated with the 55th, forming the 55th/53rd Battalion. In October 1941, during World War II, the two battalions were delinked and the 53rd was later deployed to New Guinea, where they took part in the Kokoda Track campaign. Poorly prepared and trained, and lacking up to date equipment, they did not perform well and were amalgamated with the 55th once more in October 1942, with whom they subsequently took part in further campaigns in New Guinea and Bougainville before being disbanded in May 1946.
The 30th Brigade was a brigade-sized infantry unit of the Australian Army. Formed in December 1941, as part of the Militia, the unit was raised for service during the Second World War. Established in response to Japan's entry into the war, the brigade's subordinate units were established in several Australian states. Some of these had already been dispatched to New Guinea before the brigade's headquarters was established, although the majority arrived there in early 1942. Following their arrival, the brigade initially provided garrison troops to Port Moresby before later taking part in the fighting along the Kokoda Track during which elements took part in delaying actions around Kokoda and Isurava, before being relieved by units of the Second Australian Imperial Force. After the campaign began to turn in favour of the Australians, the Japanese withdrew north towards their beachheads around Buna and Gona, and elements of the brigade were recommitted to the fighting. In early 1943, the 30th Brigade was withdrawn back to Australia and was disbanded in July 1943, with its personnel being redistributed to other formations.
The 55th Battalion was an infantry battalion of the Australian Army. Raised in 1916 for service during World War I the battalion served on the Western Front until the end of the war, before being briefly amalgamated with the 53rd Battalion and then being disbanded in 1919. In 1921, the 55th Battalion was re-raised and in 1927 adopted the title of the "New South Wales Irish Rifles". This designation was later changed to the "New South Wales Rifle Regiment" in 1930, before they were once again amalgamated with the 53rd, forming the 55th/53rd Battalion in 1937. In October 1941, during World War II, the two battalions were delinked and the 55th was later deployed to New Guinea, where they took part in the Kokoda Track campaign, fighting against the Japanese. Poorly prepared and trained, and lacking up to date equipment, they performed above expectations; however, they were amalgamated with the 53rd, which had not fared so well, once more in October 1942. The 55th/53rd subsequently took part in further campaigns in New Guinea and Bougainville before being disbanded in May 1946.
The 2/1st Field Regiment was an Australian Army artillery regiment raised as part of the all volunteer Second Australian Imperial Force during World War II. Formed in October 1939, the regiment was assigned to the 6th Division. Shortly after it was raised, the regiment was deployed to the Middle East, where it was briefly re-roled as an anti-aircraft regiment before returning to the field artillery role. In 1941, the regiment served in North Africa and in Greece, before being withdrawn back to Australian in early 1942, following Japan's entry into the war. In late 1942, and early 1943, the regiment took part in the defence of Port Moresby during the fighting along the Kokoda Track, before taking part in the Battle of Buna–Gona and the defence of Wau, remaining in New Guinea on garrison duties until August 1943. Withdrawn to Australia, a long period of training followed before the regiment took part in its final campaign of the war Aitape–Wewak campaign in 1945.
The 2/1st Machine Gun Battalion was a battalion of the Australian Army that was raised for service during World War II as part of the 6th Division. When it was formed on 14 December 1939, its component companies were spread across several Australian states, but it was later concentrated at Ingleburn, New South Wales, where it completed basic training in the early months of the war. In mid-1940, the battalion embarked for overseas, bound initially for the Middle East, but following the Fall of France it was diverted to the United Kingdom. Along with a larger contingent of Australians, it helped to bolster the island's garrison, undertaking defensive duties during a period when it was expected that the Germans might launch a cross-Channel invasion.
The 2/27th Battalion was an infantry battalion of the Australian Army during World War II. Raised in May 1940 as part of the 7th Division from volunteers from the state of South Australia, the battalion was assigned to the 21st Brigade. After completing training in Australia, the 2/27th deployed to the Middle East in November 1940, and in early 1941 undertook defensive duties in the Western Desert. The battalion's first combat experience came against the Vichy French during the short Syria–Lebanon campaign during which it fought major engagements around Sidon and Damour. At the conclusion of the fighting in Syria, the battalion remained in the area as part of the Allied occupation force until early 1942 when it was returned to Australia to fight against the Japanese.
The Battle of Mubo was a series of actions in the Mubo area of the Territory of New Guinea between Australian and Japanese forces which took place between 22 April and 14 July 1943, during World War II. The battle formed part of the wider Salamaua–Lae campaign, and was fought in the early stages of the campaign. The battle followed the successful defence of the airfield around Wau by the Australians in late January 1943, after the Japanese had attempted to infiltrate the Australian positions with two infantry battalions.
The 6th Machine Gun Battalion was a battalion of the Australian Army that was raised for service during World War II. Formed in late 1942 from the machine gun companies of several infantry battalions, the 6th Machine Gun Battalion undertook training on the New South Wales south coast before being deployed to New Guinea where they took part in the Markham and Ramu Valley – Finisterre Range campaign, defending the airfield at Gusap, and undertaking patrols. In early 1944, the battalion returned to Australia and over the course of the year was disbanded, with its personnel being sent to other units as reinforcements. Many of these personnel then saw combat in Borneo in 1945.
