Macquarie Island, a remote subantarctic territory administered by Tasmania, gained UNESCO World Heritage status in 1997 for its unique geology — it is the only place on Earth where mantle rock is being actively exposed above sea level. The island has no permanent civilian population, only a rotating Australian Antarctic Division research station that has operated continuously since 1948.
The silver-plated copper-nickel construction places this firmly in the commemorative/collector category rather than anything intended for circulation.
