The Mint partnered with ICOMOS to produce this coin in recognition of the 21st General Assembly and Scientific Symposium being held in Australia for the first time, in Sydney from 1-10 September 2023. The coin features images of all 20 Australian World Heritage Properties in intricate detailed relief, which frames a full-colour, central image of a handprint, fan palm frond and a shell fossil to represent the natural and built icons and Australia’s Indigenous heritage.
