Located in the southwest corner of the Pacific Ocean, about half-way between New Zealand and Antarctica, Macquarie Island is the only place in the world where rocks from the mantle are actively exposed at sea level. Due to this it became a world heritage site in 1997. Ecologically, it is part of the Antipodes Subantarctic Islands tundra ecoregion.
The Australian Antarctic Division (AAD) maintains a permanent base, the Macquarie Island Station, on the isthmus at the northern end of the island at the foot of Wireless Hill. The base's residents, the island's only inhabitants, range in numbers from 20 to 40 people throughout the year.
