Heard Island and McDonald Islands (abbreviated as HIMI) are a volcanic group of barren islands located in the Southern Ocean, about two-thirds of the way from Madagascar to Antarctica, approximately 4099 km south west of Perth. Discovered in the mid-19th century, they 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.
The group's overall size is 372 square kilometres (144 sq mi) in area, and it has 101.9 km of coastline. The islands are uninhabited.
