The "Bluebirds" were a group of twenty Australian civilian nurses and a masseuse who volunteered for service in France during World War I. Recruited through the Australian Red Cross Society, the group's nickname referred to the colours of their specially-designed uniforms. After arriving in France the nurses were split between different hospitals where they treated wounded and ill soldiers. They returned to Australia individually following the war and did not receive any medals or veterans' benefits from the Australian government.
Following the outbreak of World War I the Australian Red Cross Society contacted the French Government offering to provide a team of nurses. The French Government accepted this offer. The Red Cross Society subsequently placed an advertisement in the Australian press seeking medically qualified nurses who were able to speak French. A total of 90 applications were received.
Of the applicants, the Red Cross Society eventually selected 11 Sisters, nine nurses and a masseuse, among whom was Dorothy Ellena Duffy, Sister Hilda Loxton and Sister Lynette Crozier. Most of these women were aged in their late 20s or early 30s. A French teacher was also engaged to accompany the team on their voyage to Europe. The nurses signed contracts agreeing to serve for twelve months or the duration of the war, whichever was shorter. While the nurses did not form part of the military, the Department of Defence funded their passage to Europe. The Australian Jockey Club initially volunteered to pay the first six months of the Bluebirds' salaries at the same rate as those of military nurses, but may have subsequently funded the nurses' salaries for the duration of the war. The department store chain David Jones donated the nurses' distinctive uniforms, which were made from dark blue material.
The Bluebirds left Sydney on board the hospital ship HMAT Kanowna on 4 July 1916, which sailed to the United Kingdom. After arriving in France the nurses were split up and worked in different hospitals. Most served in permanently established hospitals well away from the war zone where they mainly cared for French soldiers. However, several of the nurses were assigned to a mobile hospital which operated near the front lines; this hospital was bombed by a German aircraft on one occasion, and was also near the edge of a region affected by a poison gas attack on another occasion. One of the Bluebirds was appointed the matron of a hospital, and two others were placed in charge of floors of their hospitals. None of the nurses was injured as a result of military action during the war, but several suffered from periods of prolonged illness.
