Where Are the Islands Located?
Heard and McDonald Islands (HIMI) is an external territory of Australia comprising of a volcanic group of barren Antarctic Islands. The islands are located about 1,056 miles from Antarctic continent and about 2,527 miles southwest of Perth. The group of islands covers an area of 144 square miles and has a coastline measuring 63 miles. HIMI were discovered in the mid-19th century and have been part of the Australian territory since 1947. The islands contain the country’s only two active volcanoes. As the only volcanically active subantarctic islands, they provide an opportunity for tourists to observe ongoing geomorphic and glacial processes. Heard and McDonald Islands were listed as World Heritage Site by the UNESCO in 1997.
