Orthographic projection centred over the Heard Islands
Heard Island and the McDonald Islands are uninhabited, barren islands located in the Southern Ocean at 53°6′ S 72°31′ E, about two-thirds of the way from Madagascar to Antarctica. They have been part of Australia since 1947, and contain the only two active volcanoes in Australian territory, one of which, Mawson Peak, is the highest Australian mountain.
Heard Island is bleak and mountainous, covered in glaciers and dominated by Mawson Peak, a 2745- meter-high volcano which forms part of the Big Ben massif. Mawson Peak is the highest Australian mountain, and one of only 2 active volcanoes in Australian territory.
The other active volcano in Australian territory is on McDonald Island: after being dormant for 75,000 years, it erupted in 1992 and has erupted again several times since, its most recent eruption being on 10 August 2005.
The McDonald Islands, located 44 km to the west of Heard Island, are small and rocky. They total approximately 2.5 km˛ in area and, as with Heard Island, are surface exposuers of the Kerguelen Plateau. Heard Island and the McDonald Islands have have no ports or harbors.
Administration and economy
The islands are a territory of Australia administered from Hobart by the Australian Antarctic Division of the Australian Department of the Environment and Heritage. They are populated by large numbers of seal and bird species. The islands are contained within a 65 000 square kilometre marine reserve and are primarily visited for research.
There is no economic activity, but they have been assigned the country code HM and Internet top-level domain .hm.
History

Map from The World Factbook
Heard Island did not have visitors until the mid-1850s. It is probable that no human had ever seen the Island until this time. Peter Kemp, a British sealer (seal hunter), was the first person thought to have seen the island on November 27, 1833, from the brig Magnet Heard Island And Mcdonald Island during a voyage from Kerguelen to the Antarctic and was believed to have entered the island in his 1833 chart.
Captain John Heard, an American sealer on the ship Oriental, sighted the island on November 25, 1853, en route from Boston to Melbourne. He reported the discovery one month later and had the island named after him. Coincidentally, Captain William McDonald aboard the Samarang discovered the McDonald Islands close to Heard Island shortly afterwards on January 4, 1854.
No landing was made on the islands until March 1855, when sealers from the Corinthian led by Captain Erasmus Darwin Rogers went ashore. In the sealing period from 1855–1880, a number of American sealers spent a year or more on the island, living in appalling conditions in dark smelly huts. By 1880, most of the seal population had been wiped out and the sealers left the island. In all, more than 100,000 barrels of elephant seal oil was produced during this period.
The islands have been part of Australia since 1947, and became a World Heritage Site in 1997. Polar Region Heard Mcdonald Island |
