Olive May Kelso King was an Australian adventurer and mountain climber. During World War I she drove ambulances for the Scottish Women's Hospitals and later the Serbian Army. In the final stages of the war she raised money and set up mobile canteens to help feed the Serbian people. In all, she was awarded four medals by the Serbian government for her work during the war. After World War I, King held a senior volunteer position with Girl Guides Australia. During World War II, she worked as an examiner at the Havilland Aircraft factory.

The Scottish Women's Hospitals for Foreign Services (SWH) was founded in 1914. It was led by Dr Elsie Inglis and provided nurses, doctors, ambulance drivers, cooks and orderlies. By the end of World War I, 14 medical units had been outfitted and sent to serve in Corsica, France, Malta, Romania, Russia, Salonika and Serbia.
