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 Aboriginals 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...)

Barr during World War II
Andrew William "Nicky" Barr, OBE,MC,DFC & Bar (10 December 1915 – 12 June 2006) was a member of the Australian national rugby union team, who became a fighter ace in the Royal Australian Air Force (RAAF) during World War II. He was credited with 12 aerial victories, all scored flying the Curtiss P-40 fighter. Born in New Zealand, Barr was raised in Victoria and first represented the state in rugby in 1936. Selected to play for Australia in the United Kingdom in 1939, he had just arrived in England when the tour was cancelled following the outbreak of war. He joined the RAAF in 1940 and was posted to North Africa with No. 3 Squadron in September 1941. The squadron's highest-scoring ace, he attained his first three victories in the P-40 Tomahawk and the remainder in the P-40 Kittyhawk.
Barr's achievements as a combat pilot earned him the Distinguished Flying Cross and Bar. Shortly after taking command of No. 3 Squadron in May 1942, he was shot down and captured by Axis forces, and incarcerated in Italy. He escaped and assisted other Allied fugitives to safety, receiving for his efforts the Military Cross, a rare honour for an RAAF pilot. Repatriated to England, he saw action during the invasion of Normandy in June 1944 before returning to Australia as chief instructor with No. 2 Operational Training Unit. After the war he became a company director, and rejoined the RAAF as an active reserve officer from 1951 to 1953. From the early 1960s he was heavily involved in the oilseed industry, for which he was appointed an Officer of the Order of the British Empire in 1983. He died in 2006, aged 90. (Full article...)

Thomas Baker as a cadet pilot c.1917
Thomas Charles Richmond Baker, DFC,MM & Bar (2 May 1897 – 4 November 1918) was an Australian soldier, aviator, and flying ace of the First World War. Born in Smithfield, South Australia, he was an active sportsman in his youth and developed a keen interest in aviation. He was employed as a clerk with the Bank of New South Wales, before he enlisted in the Australian Imperial Force in July 1915, for service in World War I. Posted to an artillery unit on the Western Front, he was awarded the Military Medal for carrying out numerous repairs on a communications line while subject to severe artillery fire. In June 1917, Baker was awarded a bar to his decoration for his part in quelling a fire in one of the artillery gun pits that was endangering approximately 300 rounds of shrapnel and high explosive.
In September 1917, Baker applied for a position as a mechanic in the Australian Flying Corps. He was instead selected for flight training, and was posted to courses in the United Kingdom. He graduated as a pilot and was commissioned a second lieutenant in March 1918. Posted for active duty in France that June, Baker joined the ranks of No. 4 Squadron AFC. Over the next four months, he rose to the rank of captain and was credited with bringing down 12 German aircraft. He was shot down and killed on 4 November 1918. In February 1919, he was posthumously awarded the Distinguished Flying Cross. (Full article...)
The Axis threat to Australia developed gradually and until 1942 was limited to sporadic attacks by German armed merchantmen. The level of Axis naval activity peaked in the first half of 1942 when Japanese submarines conducted anti-shipping patrols off Australia's coast, and Japanese naval aviation attacked several towns in northern Australia. The Japanese submarine offensive against Australia was renewed in the first half of 1943 but was broken off as the Allies pushed the Japanese onto the defensive. Few Axis naval vessels operated in Australian waters in 1944 and 1945, and those that did had only a limited impact. (Full article...)
Described as a "small, dapper man", who was "outspoken, even 'cocky'", Hewitt overcame the setback to his career during the war and made his most significant contributions as Air Member for Personnel from 1945 to 1948. Directly responsible for the demobilisation of thousands of wartime staff and the consolidation of what was then the world's fourth largest air force into a much smaller peacetime service, he also helped modernise education and training within the RAAF. Hewitt was appointed a Commander of the Order of the British Empire in 1951, the same year he became Air Member for Supply and Equipment. Retiring from the military in 1956, he went into business and later managed his own publishing house. He wrote two books including Adversity in Success, a first-hand account of the South West Pacific air war, before his death in 1985 aged 84. (Full article...)
John Linton Treloar, OBE (10 December 1894 – 28 January 1952), commonly referred to during his life as J. L. Treloar, was an Australian archivist and the second director of the Australian War Memorial (AWM). During World War I he served in several staff roles and later headed the First Australian Imperial Force's (AIF) record-keeping unit. From 1920 Treloar played an important role in establishing the AWM as its director. He headed an Australian Government department during the first years of World War II, and spent the remainder of the war in charge of the Australian military's history section. Treloar returned to the AWM in 1946, and continued as its director until his death.
Treloar's career was focussed on the Australian military and its history. Prior to World War I he worked as a clerk in the Department of Defence and, after volunteering for the AIF in 1914, formed part of the Australian Army officer Brudenell White's staff for most of the war's first years. He was appointed commander of the Australian War Records Section (AWRS) in 1917. In this position, he improved the AIF's records and collected a large number of artefacts for later display in Australia. Treloar was appointed the director of what eventually became the AWM in 1920, and was a key figure in establishing the Memorial and raising funds for its permanent building in Canberra. He left the AWM at the outbreak of World War II to lead the Australian Government's Department of Information, but was effectively sidelined for much of 1940. In early 1941 he was appointed to command the Australian military's Military History and Information Section with similar responsibilities to those he had held during World War I. He attempted to intervene in the management of the AWM during his absence, however, to the increasing frustration of its acting director. Treloar worked intensely in all his roles and suffered periods of ill-health as a result. Following the war, he returned to the Memorial in 1946 but his performance deteriorated over time, possibly due to exhaustion. He died in January 1952. (Full article...)
Sent to Singapore with the rest of the 8th Division, Matthews served as the brigade signals officer of the 27th Brigade during the Malayan campaign and the Battle of Singapore, and at the surrender of Singapore he became a prisoner of war (POW). While in captivity he was awarded the Military Cross for displaying a high standard of courage, energy and ability while maintaining communications under fire in the earlier fighting. In July 1942, he was a member of a group of POWs sent to the Sandakan POW camp in British North Borneo. There, Matthews established an intelligence network, collecting information, weapons, medical supplies and radio parts, and made contact with organisations outside the camp, including Filipino guerrillas who assisted POWs to escape.

Smoke rises from two Japanese aircraft shot down off Guadalcanal on 12 November 1942; ship at right is USS Betelgeuse
The Naval Battle of Guadalcanal, sometimes referred to as the Third and Fourth Battles of Savo Island, the Battle of the Solomons, TheBattle of Friday the 13th, The Night of the Big Guns, or, in Japanese sources, the Third Battle of the Solomon Sea (第三次ソロモン海戦, Dai-san-ji Soromon Kaisen), took place from 12 to 15 November 1942 and was the decisive engagement in a series of naval battles between Allied (primarily American) and Imperial Japanese forces during the months-long Guadalcanal campaign in the Solomon Islands during World War II. The action consisted of combined air and sea engagements over four days, most near Guadalcanal and all related to a Japanese effort to reinforce land forces on the island. The only two U.S. Navy admirals to be killed in a surface engagement in the war were lost in this battle.
Allied forces landed on Guadalcanal on 7 August 1942 and seized an airfield, later called Henderson Field, that was under construction by the Japanese military. There were several subsequent attempts to recapture the airfield by the Imperial Japanese Army and Navy using reinforcements delivered to Guadalcanal by ship, efforts which ultimately failed. In early November 1942, the Japanese organized a transport convoy to take 7,000 infantry troops and their equipment to Guadalcanal to attempt once again to retake the airfield. Several Japanese warship forces were assigned to bombard Henderson Field with the goal of destroying Allied aircraft that posed a threat to the convoy. Learning of the Japanese reinforcement effort, U.S. forces launched aircraft and warship attacks to defend Henderson Field and prevent the Japanese ground troops from reaching Guadalcanal.

From 31 May to 8 June 1942, during World War II, Imperial Japanese Navy submarines made a series of attacks on the Australian cities of Sydney and Newcastle. On the night of 31 May – 1 June, three Ko-hyoteki-classmidget submarines, (M-14, M-21 and M-24) each with a two-member crew, entered Sydney Harbour, avoided the partially constructed Sydney Harbour anti-submarine boom net, and attempted to sink Allied warships. Two of the midget submarines were detected and attacked before they could engage any Allied vessels. The crew of M-14 scuttled their submarine, whilst M-21 was successfully attacked and sunk. The crew of M-21 killed themselves. These submarines were later recovered by the Allies. The third submarine attempted to torpedo the heavy cruiser USS Chicago, but instead sank the converted ferry HMAS Kuttabul, killing 21 sailors. This midget submarine's fate was unknown until 2006, when amateur scuba divers discovered the wreck off Sydney's northern beaches.
Immediately following the raid, the five Japanese fleet submarines that carried the midget submarines to Australia embarked on a campaign to disrupt merchant shipping in eastern Australian waters. Over the next month, the submarines attacked at least seven merchant vessels, sinking three ships and killing 50 sailors. During this period, between midnight and 02:30 on 8 June, two of the submarines bombarded the ports of Sydney and Newcastle. (Full article...)

RAAF area commands, November 1942. Eastern Area's boundaries remained in place until it re-formed as Home Command in October 1953, beginning the supersession of the area command system.
The area command continued to function after the war, its headquarters transferring from Sydney to Glenbrook, in the Blue Mountains, in 1949. By this time, most of the RAAF's operational units—including fighter, bomber, and transport wings—were based within Eastern Area's boundaries, and the officer in command was responsible for air defence across all of Australia. In October 1953, the RAAF began reorganising its command-and-control system from one based on geography to one based on function; Eastern Area was re-formed as Home Command, which was renamed Operational Command in 1959, and Air Command in 1987.

The above map shows how the network of fortresses defended the approaches to Hobart. The shaded white areas show the effective range of the fort's gun positions.
The Hobart coastal defences are a network of now defunct coastal batteries, some of which are inter-linked with tunnels, that were designed and built by British colonial authorities in the nineteenth century to protect the city of Hobart, Tasmania, from attack by enemy warships. During the nineteenth century, the port of Hobart Town was a vital re-supply stop for international shipping and trade, and therefore a major freight hub for the British Empire. As such, it was considered vital that the colony be protected. In all, between 1804 and 1942 there were 12 permanent defensive positions constructed in the Hobart region.
Prior to Australian Federation, the island of Tasmania was a colony of the British Empire, and as such was often at war with Britain's enemies and European rivals, such as France and later Russia. The British had already established the colony of Sydney at Port Jackson in New South Wales in 1788, but soon began to consider the island of Tasmania as the potential site of a useful second colony. It was an island, cut off from the mainland of Australia and isolated geographically, making it ideal for a penal colony, and was rich in timber, a resource useful to the Royal Navy. In 1803, the British authorities decided to colonise Tasmania, and to establish a permanent settlement on the island that was at the time known as Van Diemen's Land, primarily to prevent the French from doing so. During this period tensions between Great Britain and France remained high. The two nations had been fighting the French Revolutionary Wars with each other through much of the 1790s, and would soon be engaging each other again in the Napoleonic Wars. (Full article...)

In 1911, at the Imperial Conference held in London, it was decided that aviation should be developed by the national armed forces of the British Empire. Australia became the first member of the Empire to follow this policy. By the end of 1911, the Army was advertising for pilots and mechanics. During 1912, pilots and mechanics were appointed, aircraft were ordered, the site of a flying school was chosen and the first squadron was officially raised. On 7 March 1913, the government officially announced formation of the Central Flying School (CFS) and an "Australian Aviation Corps", although that name was never widely used. (Full article...)

The Inspector-General of the Australian Defence Force Afghanistan Inquiry Report, commonly known as the Brereton Report (after the investigation head), is a report into war crimes committed by the Australian Defence Force (ADF) during the War in Afghanistan between 2005 and 2016. The investigation was led by Paul Brereton, who is both a New South Wales Supreme Court judge and a major general in the army reserve. The independent commission was initiated by the Inspector-General of the Australian Defence Force in 2016, and after a long investigation, delivered its final report on 6 November 2020. The redacted version was released publicly on 19 November 2020.
The report found evidence of 39 murders of civilians and prisoners by (or at the instruction of) members of the Australian special forces, which were subsequently covered up by ADF personnel. The report stated 25 ADF personnel were involved in the killings, including those who were "accessories" to the incident. Some of those believed to be involved were still serving with the ADF. The unlawful killings discussed by the report began in 2009, with most occurring in 2012 and 2013. (Full article...)
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...)
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...)
The assault position was directly south of the boundary between the British Fifth and Second Armies. The Canadian Corps was to attack with support of formations from the British Fifth Army to the north and the I Anzac Corps and X Corps to the south. The offensive was executed in a series of attacks with limited objectives, delivered at intervals of three or more days. The dates of the phases were tentatively given as 26 October, 30 October and 6 November with a final smaller action on 10 November. To permit time for divisional reliefs, there was a seven-day pause planned between the second and third stages, during which the Second Army took over the XVIII Corps area, north of the Canadian Corps, from the Fifth Army with the II Corps on 2 November, to assure unity of command over the central part of the attack front.

During the action, the PVA had attempted to make a breakthrough to the Imjin River along the divisional boundary between the US 1st Marine Division and the 1st Commonwealth Division to turn the Marine division's flank. Yet with well-coordinated indirect fire from the divisional artillery, including the 16th Field Regiment, Royal New Zealand Artillery, and support from British Centurion tanks of the 1st Royal Tank Regiment, 2 RAR successfully thwarted both assaults, holding the Hook. U.N sources estimated PVA casualties at 2,000 to 3,000 killed, with the majority of them inflicted by the New Zealand gunners. Meanwhile, on the left flank, US Marines had endured the brunt of the attack, repelling the PVA onslaught with infantry and artillery. Only a few hours later, the armistice agreement was signed, ultimately ending the war. Both sides subsequently withdrew 2 kilometres (1.2 mi) within 72 hours to create the 4-kilometre (2.5 mi) Korean Demilitarised Zone. (Full article...)

The 31st/51st Battalion was an infantrybattalion of the Australian Army, which served during World War II. Raised for service as part of the Militia in 1943 through the amalgamation of two previously existing battalions, the 31st/51st Battalion undertook garrison duties in Dutch New Guinea in 1943–44 before taking part in the Bougainville Campaign in 1944–45. Following the end of the war, the battalion served in the Pacific overseeing the transfer of Japanese prisoners of war and re-establishing law and order until mid-1946 when it returned to Australia and was disbanded.

Australian troops advancing towards Brunei
The Borneo campaign or Second Battle of Borneo was the last major Allied campaign in the South West Pacific Area during World War II to liberate Japanese-held British Borneo and Dutch Borneo. Designated collectively as Operation Oboe, a series of amphibious assaults between 1 May and 21 July 1945 were conducted by the Australian I Corps, under Lieutenant-General Leslie Morshead, against Imperial Japanese forces who had been occupying the island since late 1941 – early 1942. The main Japanese formation on the island was the Thirty-Seventh Army under Lieutenant-General Masao Baba, while the naval garrison was commanded by Vice-Admiral Michiaki Kamada. The Australian ground forces were supported by US and other Allied air and naval forces, with the US providing the bulk of the shipping and logistic support necessary to conduct the operation. The campaign was initially planned to involve six stages, but eventually landings were undertaken at four locations: Tarakan, Labuan, North Borneo and Balikpapan. Guerilla operations were also carried out by Dayak tribesmen and small numbers of Allied personnel in the interior of the island. While major combat operations were concluded by mid-July, localised fighting continued throughout Borneo until the end of the war in August. Initially intended to secure vital airfields and port facilities to support future operations, preparatory bombardment resulted in heavy damage to the island's infrastructure, including its oil production facilities. As a result, the strategic benefits the Allies gained from the campaign were negligible. (Full article...)
Sullivan was deployed to northern Russia with the relief force. Following a successful attack, he was a member of the rearguard of a column withdrawing across the Sheika River. As his platoon crossed the river on a crude one-plank bridge in the early hours of 11 August 1919, it came under intense fire from Bolshevik troops, and four members fell into the river. Sullivan immediately jumped in and rescued them all, one by one, and was awarded the VC for his actions. Demobilised from the British Army after completing his service, Sullivan returned to Australia and resumed his civilian career as a banker. He was in London for the coronation of King George VI as part of the Australian Coronation Contingent in 1937, when he died of head injuries received in a fall. His medal set is displayed in the Hall of Valour at the Australian War Memorial in Canberra. (Full article...)

The 2/31st Battalion was an infantrybattalion of the Australian Army that served during World War II. It was raised in June 1940 and was assigned to the 25th Brigade, 7th Division. It initially served in the United Kingdom where it undertook defensive duties before being moved to the Middle East in 1941. After taking part in the fighting in Syria and Lebanon, the battalion undertook garrison duties around Tripoli before being transferred back to Australia in 1942. In late 1942 the battalion was sent to New Guinea to fight against the Japanese along the Kokoda Track. They subsequently fought a number of battles throughout 1942, 1943 and early 1944. Their last campaign came in mid-1945 when they landed on Borneo. After the war the battalion was disbanded in March 1946. (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...)

Australian engineers move up the escarpment south of the Hongorai River in May 1945. Engineers played a vital part in the Australian advance.
The initial phase saw the Australians advance towards the Hongorai River. Following the end of the early fighting, the Australian advance towards the main Japanese concentration at Buin continued as they struck out towards the Hari and Mivo Rivers. This continued until torrential rain and flooding brought the advance to a halt short of the objective, washing away many bridges and roads upon which the Australians relied for supplies. As the Australian advance stalled, the Japanese began harassing the Australian line of communications, and as the rain stopped and the flooding subsided in late-July and into August, the Australians began making preparations to resume the advance towards Buin again. Ultimately, though, the war came to an end before the final Australian advance began, bringing the campaign to an end. (Full article...)
Virgil Paul Brennan, DFC,DFM (6 March 1920 – 13 June 1943), also known as Paul Brennan, was an Australian aviator and flying ace of the Second World War. Enlisting in the Royal Australian Air Force in November 1940, he briefly served in the European Theatre before transferring to Malta. Over the next five months, Brennan was officially credited with the destruction of 10 Axis aircraft from a total of twenty-four operational sorties. Reposted to England, he was assigned as a flying instructor and collaborated in the writing of Spitfires over Malta, a book about his experiences on the island. Returning to Australia in 1943, Brennan was killed in a flying accident at Garbutt, Queensland, in June that year. (Full article...)

Holsworthy Barracks is located in the outer south-western Sydney suburb of Holsworthy. It is part of the Holsworthy military reserve, which has been a training area and artillery range for the Australian Army since World War I. Following World War II it became a major base for the permanent component of the Australian Army in New South Wales. Following the movement of many units of the Regular Army to Darwin in the late 1990s many Army Reserve units were moved from other depots to Holsworthy Barracks, including the Headquarters of the 5th Brigade. Holsworthy Barracks is the current home to 142 Signal Squadron, the 2nd Commando Regiment (2 Cdo Regt), and the 6th Aviation Regiment.
"For dash and gallantry the bloodthirsty Scots, Australians and Canadians led the way, with the impetuous Irish close behind. The Australian to my mind were the most aggressive, and managed to keep their form in spite of their questionable discipline. Out of the line they were undoubtedly difficult to handle, but once in it they loved a fight. They were a curious mixture of toughness and sentimentality..."
