Plans to honour an unknown Australian soldier were first put forward in the 1920s but it was not until 1993 that one was at last brought home. To mark the 75th anniversary of the end of the First World War, the body of an unknown Australian soldier was recovered from Adelaide Cemetery near Villers-Bretonneux in France and transported to Australia .
After lying in state in King’s Hall in Old Parliament House, Unknown Australian Soldier was interred in the Hall of Memory at the Memorial on 11 November 1993. He was buried with a bayonet and a sprig of wattle in a Tasmanian blackwood coffin, and soil from the Pozières battlefield was scattered in his tomb.
