Heard and McDonald Islands

Heard and McDonald Islands

Heard Island and McDonald Islands are uninhabited, barren islands located in the Southern Ocean, with a complete absence of alien plants and animals, as well as human impact.

The islands have been territories of Australia since 1947, and contain the only two active volcanoes in Australian territory, one of which, Mawson Peak, is the highest Australian mountain.
