Minister for the Environment and Heritage
Dr David Kemp
9 October 2002
Federal Minister for the Environment and Heritage, Dr David Kemp, today announced that the Government has decided to proclaim the world's largest fully protected marine reserve in Australia's remote Sub Antarctic waters.
The new 6.5 million hectare Heard Island and McDonald Islands Marine Reserve is 4500 kilometres south-west of the Australian mainland and 1000 kilometres North of Antarctica. It falls within Australia's 200 mile Exclusive Economic Zone surrounding Heard and McDonald Islands.
Heard Island has Australia's only active volcano, Big Ben, which is also Australia's tallest mountain. McDonald Island's steep shoreline is so well protected that only two successful landings have been made since it was discovered over a century ago.
The new park surpasses another Australian marine reserve, the 5.8 million hectare Macquarie Island reserve, as the world's largest.
Dr Kemp said the new reserve would protect the habitat and food sources of some of the world's most spectacular sea-going creatures, including the Southern Elephant Seal, the Sub Antarctic Fur Seal, and several penguin species.
The waters of the reserve are also important to two species of Albatross - the Light-mantled sooty Albatross and the Black-browed Albatross. Bottom dwelling soft corals, glass sponges, and giant barnacles will also benefit from the protection afforded by the reserve.
Dr Kemp said the declaration would preserve, for science, and for nature, a very large area of one of the most pristine environments left on earth.
"The Heard Island and McDonald Islands Marine Reserve is being declared to protect the conservation values of the region and provide an effective conservation framework to manage the region in an integrated and ecologically sustainable manner.
"It will also provide a scientific area for study of the ecosystem within the Heard Island and McDonald Islands region.
"It is an extraordinary thing for Australians to appreciate that these Islands and their surrounding waters, out near where the rescue of Tony Bullimore took place, are essentially as much a part of Australia as Bondi Beach, or Uluru, and just as important.
"Australia has a very proud history of scientific and environmental research in Antarctica.
"The world acknowledges that we have exercised our sovereignty in the region with great responsibility, and the declaration of this major new marine reserve, the largest fully protected marine area on the planet, and second only to another Australian reserve in the same region, maintains that great tradition.
"I am immensely proud to be able to say to the world community, and to Australians, that the very good work of Australia in the Antarctic is greatly advanced by this reserve. I think Sir Douglas Mawson, our great Antarctic scientist and pioneer, would be delighted by this announcement."

Heard and McDonald Islands World Heritage Property was inscribed on the World Heritage List in 1997 for its outstanding natural universal values:
The Australian Territory of Heard Island and McDonald Islands (HIMI) lies in a remote and stormy part of the globe, near the conspicuous meeting-point of Antarctic and temperate ocean waters. The islands were unknown to humanity until the 19th century. HIMI is an external territory of Australia in the Indian Ocean sector of the Southern Ocean at around 53° 05' S and 73° 30' E. It lies about 1500 km north of Antarctica and over 4000 km south-west of Australia.
Heard Island (area 368 km2) is the principal island of HIMI. Mawson Peak, at 2745 m, is the summit of Big Ben, an active, towering volcano that dominates the group, with a thick mantle of snow and glacial ice contrasting black volcanic rocks in a startling array of forms and shapes.
McDonald Island (area 1 km2), 43.5 km due west of Heard Island, is the major island in the McDonald Islands group, which also includes Flat Island and Meyer Rock. At its highest point it rises to about 230 m. The McDonald Islands, also volcanic in origin and, like Heard Island, an undisturbed habitat for sub-Antarctic plants and animals, consists of two distinct parts joined by a narrow central isthmus.
The HIMI group can be described as the wildest place on earth-a smoking volcano under a burden of snow and glacial ice rising above the world's stormiest waters. On the horizon to the west, smaller volcanic fragments rise precipitously and defiantly out of huge Southern Ocean swells. From a distance the land is a striking monochrome-black rock and sand, white snow and ice, leaden grey seas and skies. When the sun does appear the islands light up in the clear air to a rare brilliance-verdant vegetation and multi-coloured bird colonies in sharp relief against the dazzling white of snow and ice and the grey-black of volcanic rock. The elements-hurricane-force winds, driving rain, vast amounts of snow, dense clouds and fogs-conspire with the landforms to create a world of high drama and savage beauty. The driving westerly winds above the Southern Ocean in these latitudes create unique weather patterns when they come up against the enormous bulk of Big Ben, including spectacular cloud formations around the summit and unbelievably rapid changes in winds, cloud cover and precipitation.
The other extraordinary landforms on the islands include: the flutes of Cape Pillar on McDonald Island and the lonely pinnacle of Meyer Rock; the caves and other lava formations of the northern Heard Island peninsulas; the smoking caldera of Mawson Peak above the palaeocaldera of Big Ben; the western sea cliffs of McDonald Island; the shifting sands of the Nullarbor Plain; and the extensive, dynamically changing Spit.
The vast numbers of penguins and seals that occupy the beaches here are one of the great wildlife sights of the world. Through the year the islands are home to a wide array of animals; seals, flying birds and penguins, including the world's largest macaroni penguin colonies, each containing an estimated two million birds. When the wind has died and the skies have cleared, these congregations create an incomparable cacophony of natural sound.
Heard Island is the only sub-Antarctic island on which there is an active volcano. The last recorded major eruption on Big Ben was in 1992, but continuous activity is clearly evident from other observations of minor steam and smoke emissions. The HIMI group were formed by the plume type of volcanism, a process that is poorly understood in comparison with the earth's other two main volcanic types-subduction and seafloor spreading. This feature of the group offers an extraordinary view into the earth's deep interior and its interactions with the lithospheric plates that resulted in the formation of the ocean basins and continents.
Permanent snow and ice cover 80% of Heard Island. Its steepness combines with very high snow fall at high altitudes to make the glaciers fast-flowing-in the order of 250 m a year-thus the ice and snow in the glaciers has a relatively short turnover period, around 100 years, and the glaciers respond quickly to changes in climate by advancing or retreating.
The glaciers of Heard Island provide an invaluable proxy record of climate change in this remote area, for which there are few instrumental records.
HIMI is the only sub-Antarctic island group that has an intact ecosystem. It is the only sub-Antarctic island group to contain no known species introduced directly by humans, which makes it invaluable for having, within one site, an intact set of interrelated ecosystems; terrestrial, freshwater, coastal and marine, in which the ongoing evolution of plants and animals occur in a natural state.
Heard Island's unmodified status and simple ecosystems make it an outstanding location for monitoring plant colonisation. HIMI is unequalled by any other islands in the sub-Antarctic region in this respect.
The islands host a range of seabirds. The extreme isolation and the lack of introduced predators provide an excellent location for investigating the effects of geographic isolation and climate on the evolution of species. Active speciation is clearly present. For example, the Heard shag Phalacrocorax nivalis is found nowhere else but on Heard Island. The beetle populations on HIMI show unique evolutionary adaptations to the environment and several other invertebrate groups provide valuable opportunities to study evolutionary processes in undisturbed populations at the southern limits of their distribution.
The seal and penguin populations provide excellent opportunities to monitor the health and stability of the larger Southern Ocean ecosystem. HIMI is one of the best sites in the world to study the ecological and biological processes of recolonisation of the Antarctic fur seal and the king penguin populations. It is also one of the best land-based sites in the world to study the leopard seal and its role in the sub-Antarctic ecosystem.
