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...)
Air Commodore Cobby (left) and Group Captain Caldwell at Morotai in January 1945 The "Morotai Mutiny" was an incident in April 1945 involving members of the Australian First Tactical Air Force based on the island of Morotai, in the Dutch East Indies. Eight senior pilots, including Australia's leading flying ace, Group Captain Clive Caldwell, tendered their resignations to protest what they perceived as the relegation of Royal Australian Air Force (RAAF) fighter squadrons to strategically unimportant ground attack missions against Japanese positions that had been bypassed in the Allies' "island-hopping" campaign. A government investigation vindicated the "mutineers", and three high-ranking officers at First Tactical Air Force Headquarters, including the commander, Air Commodore Harry Cobby, the Australian Flying Corps' top-scoring ace in World War I, were relieved of their posts.
George Odgers summed up the cause of the incident in the official history of the RAAF in World War II as "the conviction of a group of young leaders that they were engaging in operations that were not militarily justifiable—a conviction widely shared also by many Australian soldiers and political leaders." Odgers concluded that the ensuing inquiry "made it clear that almost everyone concerned acted from the highest motives, and was convinced that, in the crisis, he acted wisely". (Full article...)

Brill's leadership and determination to complete his missions despite damage to his aircraft—on one occasion inflicted by another Lancaster's bombs from above—earned him the Distinguished Service Order. Promoted to wing commander in May 1944, he took over No. 467 Squadron RAAF after the death in combat of its then-commander, Group Captain John Balmer. Brill was awarded a bar to his DFC in July, for his skill in evading three German night fighters. Returning to Australia, he remained in the Air Force after the war and led No. 10 Squadron in 1949–50. He went on to command air bases at Rathmines, Canberra and Townsville during the 1950s and 1960s. Brill served two terms as RAAF Director of Personnel Services, in 1956–59 and 1960–63, by which time he had been promoted to group captain. His final posting was at the Department of Air in Canberra. He died of a heart attack in October 1964. (Full article...)

John Treloar in 1922
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 a Government of Australia 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 AWM in 1946 but his performance deteriorated over time, possibly due to exhaustion. He died in January 1952. (Full article...)

Denny in c. 1910
William Joseph DennyMC (6 December 1872 – 2 May 1946) was an Australian journalist, lawyer, politician and decorated soldier who held the South Australian House of Assembly seats of West Adelaide from 1900 to 1902 and then Adelaide from 1902 to 1905 and again from 1906 to 1933. After an unsuccessful candidacy as a United Labor Party (ULP) member in 1899, he was elected as an "independent liberal" in a by-election in 1900. He was re-elected in 1902, but defeated in 1905. The following year, he was elected as a ULP candidate, and retained his seat for that party (the Australian Labor Party from 1917) until 1931. Along with the rest of the cabinet, he was ejected from the Australian Labor Party in 1931, and was a member of the Parliamentary Labor Party until his electoral defeat at the hands of a Lang Labor Party candidate in 1933.
Bruce Steel Kingsbury, VC (8 January 1918 – 29 August 1942) was an Australian soldier of the Second World War. Serving initially in the Middle East, he later gained renown for his actions during the Battle of Isurava, one of many battles forming the Kokoda Track Campaign in the south-east of the island of New Guinea, then part of the Australian Territory of Papua (now Papua New Guinea) . His bravery during the battle was recognised with the Victoria Cross, the highest decoration for gallantry "in the face of the enemy" that can be awarded to members of the British and Commonwealth armed forces. The first serviceman to receive the VC for actions on Australian territory, Kingsbury was a member of the 2/14th Infantry Battalion.
On 29 August 1942, during the Battle of Isurava, Kingsbury was one of the few survivors of a platoon that had been overrun by the Japanese. He immediately volunteered to join a different platoon, which had been ordered to counter-attack. Rushing forward and firing his Bren gun from the hip, he cleared a path through the enemy and inflicted several casualties. Kingsbury was then shot by a sniper and killed instantly. His actions, which delayed the Japanese long enough for the Australians to fortify their positions, were instrumental in saving his battalion's headquarters and he was posthumously awarded the Victoria Cross as a result.

No. 79 Squadron is a Royal Australian Air Force (RAAF) flight training unit that has been formed on four occasions since 1943. The squadron was established in May 1943 as a fighter unit equipped with Supermarine Spitfires, and subsequently saw combat in the South West Pacific theatre of World War II. Between June 1943 and the end of the war in August 1945 it flew air defence patrols to protect Allied bases and ships, escorted Australian and United States aircraft, and attacked Japanese positions. The squadron was disbanded in November 1945, but was re-formed between 1962 and 1968 to operate CAC Sabres from Ubon Air Base in Thailand. In this role it contributed to the defence of Thailand against a feared attack from its neighbouring states and exercised with United States Air Force units. No. 79 Squadron was active again at RAAF Base Butterworth in Malaysia between 1986 and 1988 where it operated Mirage III fighters and a single DHC-4 Caribou transport during the period in which the RAAF's fighter squadrons were transitioning to new aircraft.
The squadron was re-formed in its present incarnation during 1998 and is currently stationed at RAAF Base Pearce, where it has operated Hawk 127 (upgraded to Hawk 128 standard) jet training aircraft since 2000. The unit's main role is to provide introductory jet aircraft training to RAAF pilots as well as refresher training on the Hawk for experienced pilots. No. 79 Squadron also supports Australian Army and Royal Australian Navy training exercises in Western Australia and the Northern Territory. (Full article...)
Major GeneralElizabeth Cosson, AM, CSC (born 1958) served as Secretary of the Department of Veterans' Affairs from 2018-2023. Cosson "vowed" to resign as Secretary of the Department of Veterans’ Affairs, on 19 July 2020, if she cannot improve the department’s relationship with veterans stating in a media interview on 19 July 2019 that "if I’m still part of the problem in 12 months I will hand over [the job]."
Between 1979 and 2010, Cosson served 31 years in the Australian Army as an officer, commencing with officer training in the Women's Royal Australian Army Corps (WRAAC) on 22 February 1979 (when she was 20 years old) at Georges Heights (WRAAC OCS 28/79 – the first WRAAC Officer course to have a similar syllabus and training duration as the male officer cadets had, and coming only a year after servicewomen first received the right to equal pay). In 1983 she was transferred to the Royal Australian Army Ordnance Corps, as the WRAACs disbanded. (Full article...)
The Yeramba was an Australian self-propelled howitzer built after the end of the Second World War in the late-1940s. They were produced by mounting the 25 pounder gun-howitzer on an American M3A5 Grant tank hull, and were converted by the Ordnance Factory in Bendigo from 1950 to 1952. The Yeramba was withdrawn from service in 1957 after becoming obsolete. The name is from the yeramba, an Aboriginal instrument for throwing spears. (Full article...)

Australian and American troops dug in together during the Battle of Hamel
Many of the tactics employed, such as the use of combined arms, illustrated the evolution of military tactics, from the massed attacks mounted earlier in the war. The objectives were achieved within 93 minutes, just three minutes longer than Monash's calculated battle time. (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.

Fort Lytton National Park is a national park in Lytton, City of Brisbane, Queensland, Australia. Its main attraction is Fort Lytton Historic Military Precinct, providing guided tours of historic Fort Lytton, a museum and re-enactments. The park was created in 1990 as Queensland's first historic national park. It initially contained only heritage-listed Fort Lytton, a colonial coastal fort that continued to operate as a military base until after the Second World War. The park was extended in 1999 to include Lytton Quarantine Station which occupied adjacent land. The Quarantine Station is also heritage-listed, but is only open to the public on special occasions.
During the 1980s, the RAN began plans to replace the River-classdestroyer escorts (based on the British Leander-class frigate) with a mid-capability patrol frigate and settled on the idea of modifying a proven German design for Australian conditions. Around the same time, the RNZN was seeking to replace their Leander-class frigates while maintaining blue-water capabilities. A souring of relations between New Zealand and the United States in relation to New Zealand's nuclear-free zone and the ANZUS security treaty prompted New Zealand to seek improved ties with other nations, particularly Australia. As both nations were seeking warships of similar capabilities, the decision was made in 1987 to collaborate on their acquisition. (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...)

Troops from 'C' Company, 2/48th Battalion advance alongside Matilda tanks from the 2/9th Armoured Regiment during the attack on the "Sykes" feature on Tarakan in April 1945
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.

A No. 5 Airfield Construction Squadron bulldozer working in a coral quarry at Noemfoor Island during December 1944
No. 5 Airfield Construction Squadron (5ACS) was a Royal Australian Air Force (RAAF) construction squadron. The unit was first formed in July 1942 and served in the New Guinea Campaign and Borneo Campaign during World War II. The squadron was one of only a few RAAF airfield construction units to be retained at the end of the war, and formed part of Australia's contribution to the occupation of Japan from 1945 until it was disbanded in June 1949. 5ACS was re-raised in August 1951 and worked on several RAAF airfields in Australia. It also provided small detachments of engineers to support RAAF deployments to South Vietnam and Thailand during the Vietnam War. The squadron was the RAAF's only airfield construction unit from 1961 onward, and was disbanded in December 1974. (Full article...)

The Australian Army Reserve is a collective name given to the reserve units of the Australian Army. Since the Federation of Australia in 1901, the reserve military force has been known by many names, including the Citizens Forces, the Citizen Military Forces, the Militia and, unofficially, the Australian Military Forces. In 1980, however, the current name—Australian Army Reserve—was officially adopted, and it now consists of a number of components based around the level of commitment and training obligation that its members are required to meet.

Chinese dead on the approaches to the Hook, late July 1953
During the action, the PVA 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 1st 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. UN 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 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...)

Squadron Leader Jackson commanding No. 75 Squadron in New Guinea, September 1942
Jackson took over command of No. 75 Squadron after his brother was killed in action on 28 April 1942, leading it in the Battle of Milne Bay later that year. Credited with a fifth aerial victory, he became the RAAF's first ace in the New Guinea campaign, and was awarded the Distinguished Flying Cross (DFC). By 1944, Jackson was wing leader of No. 78 (Fighter) Wing in Western New Guinea, gaining promotion to wing commander in September that year. Awarded a bar to his DFC in March 1945, he served as chief flying instructor at No. 8 Operational Training Unit in Australia, and saw out the war as commander of Air Defence Headquarters, Madang. After leaving the RAAF in 1946, Jackson returned to the business world, running two garages. He died in Southport, Queensland, in 1980. (Full article...)

Sergeant Tom Derrick raising the Australian flag over Sattelberg mission
The Battle of Sattelberg took place between 17 and 25 November 1943, during the Huon Peninsula campaign of the Second World War. Involving forces from Australia, the United States and Japan, the fighting centred on the Sattelberg mission station which was situated atop a hill about 900 metres (3,000 ft) above sea level, approximately 8 kilometres (5.0 mi) inland from Finschhafen, New Guinea. Following the Australian landing at Scarlet Beach a large force of Japanese had retreated inland towards Sattelberg. The Japanese, holding the high ground, subsequently threatened the Australian lines of communication as they advanced south towards Finschhafen. The Australian 26th Brigade was tasked with capturing the mission to neutralise this threat. Over the course of 10 days they advanced west from Jivevaneng up the southern approaches to the mission, reducing the Japanese position with armour, artillery, and air support. The Japanese finally abandoned Sattelberg and withdrew north to Wareo, having suffered heavy casualties and running low on supplies. (Full article...)
After completing training, No. 78 Squadron was deployed to the combat zone north of Australia in October 1943. From November that year until September 1944 the squadron supported the advance of the Allied ground forces through western New Britain and the north coast of New Guinea by attacking Japanese positions, providing fighter protection for recently established beachheads, and escorting Australian and United States bombers. From late 1944 until mid-1945 it operated against Japanese positions and shipping in the eastern Netherlands East Indies. The squadron took part in the Borneo campaign during the final weeks of the war. No. 78 Squadron was reduced to a cadre after it returned to Australia in December 1945, but received new aircraft in 1946 and undertook training exercises until being disbanded in April 1948.

Australian troops withdraw from Ratsua on to the Soraken Peninsula following the end of hostilities, August 1945
The fighting occurred following a failed landing by Australian forces at Porton Plantation in early June, which was part of an attempt to outflank a series of strong points that the Japanese had built across the base of the Bonis Peninsula. After this, the fighting in the northern sector around Ratsua essentially became a containment action for the Australians as they concentrated their efforts and resources upon driving south towards Buin, which was the main centre of Japanese resistance on the island at the time. As a result, the situation around Ratsua remained largely static until the end of hostilities in mid-August 1945. (Full article...)

The Australian Women's Land Army (AWLA) was an organization created in World War II to combat rising labour shortages in the farming sector. The AWLA was formed on 27 July 1942 and was modelled on Women's Land Army in Great Britain. When Japan joined the Axis in 1941 male agricultural labour was recruited into the Australian military to defend the country. To meet the shortfall in rural labour, state and private women’s land organisations began to form under the jurisdiction of the Director General of Manpower. The AWLA disbanded on 31 December 1945.
