Heard Island and McDonald Islands is an Australian territory comprising uninhabited, barren islands in the Southern Ocean, about two-thirds of the way from Madagascar to Antarctica. The islands have been a territory of Australia since 1947 and became a World Heritage Site in 1997. It contains the only two active volcanoes in Australian territory, one of which, Mawson Peak, is the highest Australian mountain.
