Macquarie Island
Macquarie Island - external site lies 1,500 kilometres south-east of Tasmania in the Southern Ocean. The island is the exposed crest of the enormous Macquarie Ridge - external site and is the only place on earth where rocks from the earth's mantle (6 kilometres below the ocean floor) are being actively exposed above sea level.

In 1996, the Australian government nominated Macquarie Island for World Heritage listing based on its unique geological features. The island was inscribed on the World Heritage list in 1997. Macquarie Island
For more than 50 years, the northern part of the island has been the base for a research and Antarctic Support Station - external site. Built in 1948, the station hosts more than 40 people over the summer and about 20 people during winter. Macquarie Island
