Beginning with the New South Wales Army Nursing Service Reserve (NSWANSR), the Boer War was the first occasion in which Australian nurses served abroad for military purpose. As this was before Australia was united in 1901, each colony individually sent a reserve of nurses to South Africa where they worked with the British to aid wounded soldiers. New South Wales was the first to allow this, with other colonies following their lead shortly, despite some backlash against allowing women to go to war. After the war, the various reserves were brought together as one in the Australian Army Nursing Service, established in 1903.
Over 2861 nurses from the Australian Army Nursing Service (AANS), now much larger than when it had been established, served overseas in the First World War. An additional 423 served as support in Australia. Nurses were spread across Europe and Asia, working at numerous military and mobile hospitals established to support soldiers on the battlefield. Their work did not end after the war finished, however- many of the soldiers who fought needed care and recovery assistance in the years following, which was aided greatly by the work of the AANS.
3477 nurses joined the AANS to serve in World War II, an organisation which was recognised as part of the Australian Military Forces in 1943 in response to their significant efforts and contributions during wartimes. Soon, these nurses were joined by the newly established Royal Australian Air Force Nursing Service (RAAFNS) in 1940, and the Royal Australian Navy Nursing Service (RANNS) in 1942. Despite this, the AANS remained as the largest sector of nurses working overseas throughout the war. After the war, in 1948, the AANS were recognised officially as the Royal Australian Army Nursing Service.
153 Australian nurses served in the Korean War, as members of the RAANS- which later became the Royal Australian Army Nursing Corps (RAANC)- and the RAAFNS. These nurses served at the British Commonwealth Medical Zone Mobile Surgical Hospital in Seoul, Korea, or in Japan; working as either part of a line of medical transport through Iwakuni taking soldiers from the war zone, or at the British Commonwealth General Hospital in Kure where these soldiers were transported to. The RAAFNS assisted in preparing the wounded for air travel on this route, and accompanied many of them on the flight- taking over 12,762 wounded individuals over three years from 1950-1953.
The involvement of Australian army personnel and medical personnel occurred at different times throughout the Malayan Emergency. In 1955, when an estimated 33 Australian nurses from the RAANC departed to work across various British Military Hospitals throughout the remainder of the conflict. Unfortunately, due to poor record-keeping of this event, much of the exact information, numbers and level of involvement of the Australian nurses remains unknown. It is believed that a number of the nurses continued their stay through the end of the conflict into the early 1960’s, supporting the remainder of the British and Australian forces there.
Australian nurses by the modern era have often been incorporated into the ranks of the forces they worked alongside, rather than being kept as separate branches. These nurses are now a medical division of the Australian Defence Force (ADF), working with doctors and other medical personnel. These medical forces served in Afghanistan until the evacuation of troops in 2021.
