History
The 1939-1945 Star is the first and most widely qualifying of the Second World War campaign stars, awarded for a period of operational service overseas between 3 September 1939 and the end of the war, 8 May 1945 in Europe and 2 September 1945 in the Far East. The qualifying period was generally six months of operational service, reduced to two months for aircrew and varying by service, and it was the star from which entitlement to the other campaign stars followed.
Its ribbon carries the colours of the three services, and it bears a single clasp, Battle of Britain, for the aircrew of Fighter Command in that battle. The whole family of Second World War stars was governed by a limit of five to any one person, with further entitlements shown by clasps. The ribbon colours are believed to have been chosen personally by King George VI. As an Imperial award it retains its place in the Australian Order of Wearing.
