2 Dollars - Elizabeth II Willis Islands

The Willis Islets — a tiny coral atoll in the Coral Sea roughly 450 kilometres east of Mackay — were claimed by Australia in 1969 and remain one of the country's most obscure external territories, essentially uninhabited except for an automated weather station. This coin belongs to Australia's ongoing Territories series, which has quietly documented possessions that rarely appear on any map a general reader would consult.
