Welcome to the Military history of Australia portal!
The military history of Australia spans the nation's 230-year modern history, from the early Australian frontier wars between Aboriginal people and Europeans to the ongoing conflicts in Iraq and Afghanistan in the early 21st century. Although this history is short when compared to that of many other nations, Australia has been involved in numerous conflicts and wars, and war and military service have been significant influences on Australian society and national identity, including the Anzac spirit. The relationship between war and Australian society has also been shaped by the enduring themes of Australian strategic culture and the unique security challenges it faces.
The six British colonies in Australia participated in some of Britain's wars of the 19th century. In the early 20th century, as a federated dominion and later as an independent nation, Australia fought in the First World War and Second World War, as well as in the wars in Korea, Malaya, Borneo and Vietnam during the Cold War. In the Post-Vietnam era Australian forces have been involved in numerous international peacekeeping missions, through the United Nations and other agencies, including in the Sinai, Persian Gulf, Rwanda, Somalia, East Timor and the Solomon Islands, as well as many overseas humanitarian relief operations, while more recently they have also fought as part of multi-lateral forces in Iraq and Afghanistan. In total, nearly 103,000 Australians died during these conflicts. (Full article...)
The area command continued to operate after the war, but its assets and staffing were much reduced. Its responsibilities were subsumed in February 1954 by the RAAF's new functional commands: Home (operational), Training, and Maintenance Commands. Western Area headquarters was disbanded in November 1956. (Full article...)

United States Marines wade ashore on Tulagi Island on 7 August 1942.
U.S. Marines (USMC) of the 1st Marine Division, under the overall command of U.S. Major GeneralAlexander Vandegrift, with the USMC invasion force under the direct command of Brigadier GeneralWilliam Rupertus, captured the islands of Tulagi, Gavutu, and Tanambogo among which the Japanese Navy had constructed a naval and seaplane base. The landings were fiercely resisted by the Japanese Navy troops who, heavily outnumbered and outgunned by the Allied forces, fought and died almost to the last man. (Full article...)

Australian Hospital Ship (AHS) Centaur was a hospital ship which was attacked and sunk by a Japanese submarine off the coast of Queensland, Australia, on 14 May 1943. Of the 332 medical personnel and civilian crew aboard, 268 died, including 63 of the 65 army personnel.
In the second phase of the operation, the 17th Australian Infantry Brigade exploited the breach made in the perimeter and pressed south as far as a secondary line of defences known as the Switch Line. On the second day, the 16th Australian Infantry Brigade captured the township of Bardia, cutting the fortress in two. Thousands more prisoners were taken and the Italian garrison now held out only in the northern and southernmost parts of the fortress. On the third day, the 19th Australian Infantry Brigade advanced south from Bardia, supported by artillery and the six operational Matilda tanks. Its advance allowed the 17th Australian Infantry Brigade to make progress as well and the two brigades reduced the southern sector of the fortress. The Italian garrisons in the north surrendered to the 16th Australia Infantry Brigade and the Support Group of the 7th Armoured Division outside the fortress. In all, some 36,000 Italian prisoners were taken. (Full article...)
Pentland served in the fledgling Royal Australian Air Force (RAAF), and later the Royal Air Force, before going into business in 1927. His ventures included commercial flying around the goldfields of New Guinea, aircraft design and manufacture, flight instruction, and charter work. In the early 1930s, he was employed as a pilot with Australian National Airways, and also spent time as a dairy farmer. Soon after the outbreak of World War II, he re-enlisted in the RAAF, attaining the rank of squadron leader and commanding rescue and communications units in the South West Pacific. Perhaps the oldest operational pilot in the wartime RAAF, Pentland was responsible for rescuing airmen, soldiers and civilians, and earned the Air Force Cross for his "outstanding courage, initiative and skill". He became a trader in New Guinea when the war ended in 1945, and later a coffee planter. Retiring in 1959, he died in 1983 at the age of eighty-nine. (Full article...)

After the arrival of the First Fleet in 1788, the colony of New South Wales was initially defended by a force of three companies of marines. In 1790 this force was relieved by a specially raised corps, known as the New South Wales Corps, which provided colonial defence until 1810 when they were returned to England following the events of the Rum Rebellion. After this, regular British Army regiments were dispatched to the Australian colonies on a rotational basis, to serve as a colonial garrison for the next 60 years. The first regiment to arrive was the 73rd, who were brought to colony to replace the New South Wales Corps by Lachlan Macquarie. (Full article...)
Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s, with the selection of the Aegis combat system as the intended combat system and ASC Pty Ltd (ASC) as the primary shipbuilder in 2005. In late 2005, the AWD Alliance was formed as a consortium of the Defence Materiel Organisation (DMO), ASC, and Raytheon. Between 2005 and 2007, Gibbs & Cox's Evolved Arleigh Burke-class destroyer concept and Navantia's Álvaro de Bazán-class frigate competed for selection as the AWD design. Although the Arleigh Burke design was larger and more capable, the Álvaro de Bazán design was selected in June 2007 as it was an existing design and would be cheaper, quicker, and less risky to build.

The Armidale class is a class of patrol boats built for the Royal Australian Navy (RAN). Planning for a class of vessels to replace the fifteen Fremantle-class patrol boats began in 1993 as a joint project with the Royal Malaysian Navy, but was cancelled when Malaysia pulled out of the process. The project was reopened in 1999 under the designation SEA 1444, with the RAN as the sole participant. Of the seven proposals tendered, the Austal/Defence Maritime Services (DMS) proposal for twelve vessels based on an enlarged Bay-class patrol boat was selected. Two additional boats were ordered in 2005 to provide a dedicated patrol force for the North West Shelf Venture.
Towards the end of the nineteenth century, an escalating conflict between the British Empire and the Boer republics of southern Africa, led to the outbreak of the Second Boer War, which lasted from 11 October 1899, until 31 May 1902. In a show of support for the empire, the governments of the self-governing British colonies of Canada, New Zealand, Natal, Cape Colony and the six Australian colonies all offered men to participate in the conflict. The Australian contingents, numbering over 16,000 men, were the largest contribution from the Empire, and a further 7,000 Australian men served with other colonial or irregular units. At least 60 Australian women also served in the conflict as nurses. (Full article...)

Although most Australian civilians lived far from the front line, the Australian home front during World War II played a significant role in the Allied victory and led to permanent changes to Australian society.
During the war the Government of Australia greatly expanded its powers in order to better direct the war effort, and Australia's industrial and human resources were focused on supporting the Allied armed forces. While there were only a relatively small number of attacks on civilian targets, many Australians feared that the country would be invaded during the early years of the Pacific War. (Full article...)
The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on 21 July and overran western New Guinea (part of the Netherlands East Indies) beginning on 29 March. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies—consisting primarily of Australian forces—cleared the Japanese first from Papua, then New Guinea, and finally from the Dutch colony.
The campaign resulted in a crushing defeat and heavy losses for the Empire of Japan. As in most Pacific War campaigns, disease and starvation claimed more Japanese lives than enemy action. Most Japanese troops never even came into contact with Allied forces and were instead simply cut off and subjected to an effective blockade by Allied naval forces. Garrisons were effectively besieged and denied shipments of food and medical supplies, and as a result some claim that 97% of Japanese deaths in this campaign were from non-combat causes. According to John Laffin, the campaign "was arguably the most arduous fought by any Allied troops during World War II." (Full article...)
American manned Alligators during the landing of Australian troops at Balikpapan, Borneo
The Battle of Balikpapan was the concluding stage of Operation Oboe, the campaign to liberate Japanese-held British and Dutch Borneo. The landings took place on 1 July 1945. The Australian 7th Division, composed of the 18th, 21st and 25th Infantry Brigades, with a small number of Netherlands East Indies KNIL troops, made an amphibious landing, codenamed Operation Oboe Two, a few miles north of Balikpapan. The Allied invasion fleet consisted of around 100 ships. The landing had been preceded by heavy bombing and shelling by Australian and US air and naval forces. The Allied force totalled 33,000 personnel and was commanded by Major General Edward Milford, while the Japanese force, commanded by Rear Admiral Michiaki Kamada, numbered between 8,400 and 10,000, of which between 3,100 and 3,900 were combatants. After the initial landing, the Allies secured the town and its port, and then advanced along the coast and into the hinterland, capturing the two Japanese airfields. Major combat operations concluded around 21 July, but were followed by mopping-up operations, which lasted until the end of the war in mid-August. Australian troops remained in the area until early 1946. (Full article...)

During the campaign in New Guinea, the battalion took part in the advance on Lae during the Salamaua–Lae campaign and the fighting around Finschhafen and Sattelberg, during the Huon Peninsula campaign. Following this it was withdrawn to Australia, where it remained for over a year. In mid-1945, the 2/48th Battalion took part in the landing on Tarakan, which was its final involvement in the war. It was disbanded in October 1945 and is considered to be Australia's most highly decorated unit of the war, with four members receiving the Victoria Cross, the nation's highest decoration for gallantry, while over 90 other decorations were also made to its members.

Crusader in December 1945
Crusader (AV2767) was an Australian Army amphibious operations support ship of World War II. She was launched shortly before the war ended and entered service in late 1935. From 1945 to 1947 she was mainly used to return Australian Army equipment from the islands off New Guinea. She was also loaned to the Australian Shipping Board in early 1947 and transported earth moving equipment and timber between Melbourne and Tasmania. However, the Army did not need a ship with Crusader's capabilities after the war, and she was sold in 1947 to the Queensland Cement and Lime Company which operated her as a coral barge on the Brisbane River until the mid-1980s. The ship was scuttled in 1986 and became a popular dive wreck. (Full article...)

No. 285 Squadron was a Royal Australian Air Force (RAAF) training squadron. Controlled by No. 84 Wing, the squadron was formed in August 1999 to train the RAAF's Lockheed Martin C-130J Hercules aircrew and ground support staff. No. 285 Squadron did not control any flying aircraft but managed the flight simulator used for converting aircrew to the C-130Js operated by No. 37 Squadron. It was also allocated decommissioned Hercules airframes for training purposes, as well as flying aircraft from No. 37 Squadron when required. Throughout its existence, No. 285 Squadron was located at RAAF Base Richmond in the western suburbs of Sydney. The squadron was disbanded in December 2017. (Full article...)

The Battle of Coral–Balmoral (12 May – 6 June 1968) was a series of actions fought during the Vietnam War between the 1st Australian Task Force (1 ATF) and the North VietnamesePeople's Army of Vietnam (PAVN) 7th Division and Viet Cong (VC) Main Force units, 40 kilometres (25 mi) north-east of Saigon. Following the defeat of the PAVN/VC Tet offensive in January and February, in late April two Australian infantry battalions—the 1st and 3rd Battalions of the Royal Australian Regiment (RAR)—with supporting arms, were again deployed from their base at Nui Dat in Phước Tuy Province to positions astride infiltration routes leading to Saigon to interdict renewed movement against the capital. Part of the wider allied Operation Toan Thang I, it was launched in response to intelligence reports of another impending PAVN/VC offensive, yet the Australians experienced little fighting during this period. Meanwhile, the PAVN/VC successfully penetrated the capital on 5 May, plunging Saigon into chaos during the May Offensive in an attempt to influence the upcoming Paris peace talks scheduled to begin on the 13th. During three days of intense fighting the attacks were repelled by US and South Vietnamese forces, and although another attack was launched by the PAVN/VC several days later, the offensive was again defeated with significant losses on both sides, causing extensive damage to Saigon and many civilian casualties. By 12 May the fighting was over, and the PAVN/VC were forced to withdraw having suffered heavy casualties. US casualties were also heavy and it proved to be their most costly week of the war.
1 ATF was redeployed on 12 May to obstruct the withdrawal of forces from the capital, with two battalions establishing a fire support base named FSB Coral, just east of Lai Khê in Bình Dương Province, in an area of operations known as AO Surfers. However, poor reconnaissance and inadequate operational planning led to delays and confusion during the fly-in, and the Australians had only partially completed FSB Coral by the evening. The PAVN mounted a number of battalion-sized assaults on the night of 12/13 May, with a heavy bombardment from 03:30 signalling the start. Exploiting the disorganised defence to penetrate the Australian perimeter, the PAVN 141st Regiment temporarily captured a forward gun position during close-quarters fighting, before being repulsed by superior firepower that morning. Casualties were heavy on both sides, but the Australians had won a convincing victory. The following day 1 RAR was deployed to defend FSB Coral, while 3 RAR established FSB Coogee to the west to ambush staging areas and infiltration routes. Coral was again assaulted in the early hours of 16 May, coming under a heavy barrage followed by another regimental-sized attack. Again the base was penetrated, but after a six-hour battle the PAVN were forced to withdraw after suffering heavy losses. Expecting further fighting, the Australians were subsequently reinforced with Centurion tanks and additional artillery. On 22 May, FSB Coral was again attacked overnight, coming under a short but accurate mortar bombardment which was broken up by Australian artillery and mortars. (Full article...)

'C' Company, 2/9th Battalion during the fighting on Shaggy Ridge, January 1944
In early 1942, the 2/9th was brought back to Australia where it was re-organised for jungle warfare and took part in the New Guinea campaign. Throughout 1942–1944, the battalion was committed twice to the fighting against the Japanese in New Guinea. In 1942–1943, the 2/9th fought actions at Milne Bay and Buna–Gona before being withdrawn to Australia for rest prior to returning to New Guinea to take part in the advance through the Finisterre Range where the battalion took part in the Battle of Shaggy Ridge in 1943–1944. The battalion's final involvement in the war came during the Borneo campaign in mid-1945, when it took part in the landing at Balikpapan. It was disbanded shortly after the war in early 1946.

In view of the result of attained at the Washington Treaty which, my advisors believe, guarantee peace in the Pacific for some time to come, it is proposed to reduce the establishment of the navy and army, and postpone the expansion of the air force.
