WW2 Australian Civil Construction Corps (CCC) lapel badge.

This original Civil Construction Corps (CCC) cap badge dates to the Second World War period, circa 1942–1945, and was manufactured in Australia by the well-known maker Armour of Sydney. The CCC was a vital wartime organisation responsible for building and maintaining roads, airstrips, bridges and military infrastructure across Australia and the South West Pacific, playing a crucial behind-the-scenes role in the Allied war effort.
