The Civilian Service Medal 1939-1945 recognises the service of Australian civilians who worked in organisations such as the Australian Women’s Land Army (AWLA), the Civil Constructional Corps (CCC) and the Red Cross Emergency Service Companies during World War II.

The medal was introduced on the recommendation of the Committee of Inquiry into Defence and Defence-related Awards. The Civilian Service Medal 1939-1945 was established on 28 October 1994 by Letters Patent. Recipients must have served for a qualifying period in any one or a combination of the 38 eligible groups between 3 September 1939 and 2 September 1945.

The Civilian Service Medal 1939-1945 is bronze and portrays the Southern Cross surrounded by goldern wattle, Australias floral emblem.
