Macquarie Island lies in the southwest corner of the Pacific Ocean, about half-way between Australia and Antarctica. Politically, it has formed part of the Australian state of Tasmania since 1900 and became a Tasmanian State Reserve in 1978. In 1997 it became a World Heritage Site. The Australian Antarctic Division (AAD) maintains a permanent base on the island. The base's residents, the island's only inhabitants, range in numbers from 20 to 40 people throughout the year.
