2013 marks the centenary of the first Australian Commonwealth stamp issue. Prior to 1913, the colonies had produced their own stamps for some 60 years, creating the rich philatelic heritage celebrated in our Colonial Heritage stamp series. Two designs were combined at the behest of Postmaster-General Charles Frazer, and the resultant Kangaroo and Map design proved controversial: the king's head was absent, a kangaroo was adopted as a national symbol and the design was considered rudimentary. In the years since its release, it has become the most desirable Australian stamp issue.
