The Women's Royal Australian Naval Service (WRANS) was the women's branch of the Royal Australian Navy (RAN). In 1941, fourteen members of the civilian Women's Emergency Signalling Corps (WESC) were recruited for wireless telegraphy work at the Royal Australian Navy Wireless/Transmitting Station Canberra, as part of a trial to free up men for service aboard ships. Although the RAN and the Australian government were initially reluctant to support the idea, the demand for seagoing personnel imposed by the Pacific War saw the WRANS formally established as a women's auxiliary service in 1942. The surge in recruitment led to the development of an internal officer corps. Over the course of World War II, over 3,000 women served in the WRANS.
The organisation was disbanded in 1947, but was reestablished in 1951 in response to the manpower demand caused by Cold War commitments. In 1959, the WRANS was designated a permanent part of the Australian military. The WRANS continued to operate until 1985, when female personnel were integrated into the RAN.
In March 1939, Florence Violet McKenzie set up the Women's Emergency Signalling Corps (WESC) as wireless telegraphy organisation for female volunteers. McKenzie established the WESC because of the threat of war, and her belief that training women in wireless telegraphy, morse code, and related skills meant they could free up men for military service. By August 1940, there was a waiting list of 600 women for the small school, and WESC-trained telegraphists were teaching men from the armed forces and merchant navy.
Inspired by an article on the Women's Royal Naval Service, McKenzie contacted the RAN on several occasions to suggest that her telegraphists be employed by the RAN. Although initial letters were unanswered, she was eventually contacted by the Director of Signals and Communications, who proposed an experimental trial. There was opposition from both the government and the Australian Commonwealth Naval Board, although they eventually agreed to the trial after realising there were few other sources of trained telegraphists that could meet RAN requirements. Even so, the employment was approved on the condition that there was no publicity attached to the recruitment. Fourteen women from the WESC (12 telegraphists and 2 cooks) were accepted for naval service on 28 April 1941 and employed at the Royal Australian Navy Wireless/Transmitting Station Canberra. Six months later, another nine women were recruited. Although treated as naval personnel, the women were technically civilian employees of the RAN. Despite the formation of women's auxiliaries in the Army and Air Force, the RAN remained reluctant to formally enlist the telegraphists.
