Macquarie Island

Macquarie Island is a subantarctic island administered by Tasmania, Australia, located in the Southern Ocean between New Zealand and Antarctica. It is notable for exposed sections of oceanic crust and mantle uplifted above sea level.

The island is a significant breeding site for seabirds, penguins and seals, and hosts long-term ecological research and conservation programs. Visitors with permission encounter large colonies of royal and eastern rockhopper penguins, extensive seal haul-outs and active seabird monitoring locations.

European sealing and whaling in the 19th century heavily affected wildlife populations; subsequent protection and scientific management began in the 20th century. The Australian government now manages the island for conservation and research, with ongoing eradication and habitat restoration projects.

Macquarie Island lies roughly between Tasmania and New Zealand in the subantarctic region and is administered by the Australian state of Tasmania. The environment is cold, windy and largely treeless, dominated by tussock grasslands and rocky shores.

• World Heritage status: Inscribed as a UNESCO World Heritage property for its geological significance and as an example of ongoing geological processes on oceanic crust and mantle exposed above sea level.
• Access restrictions: Access is strictly regulated; landing and tourism are limited and generally restricted to permitted scientific or conservation visits to protect wildlife and fragile habitats.
