Macquarie Island is part of Tasmania, Australia
Macquarie Island is an oceanic island in the Southern Ocean, about halfway between New Zealand and Antarctica. It has been governed as a part of Tasmania, Australia, since 1880. The island is about 1,500 km southeast of Tasmania and is the only known breeding ground of the royal penguin. Macquarie Island is also home to the entire royal penguin population during their annual nesting season.
The island was discovered in 1810 by Frederick Hasselborough, an Australian sealer, who named it for Lachlan Macquarie, then governor of New South Wales. Hasselborough also noted the presence of a wrecked ship of presumably Polynesian design. The island was a centre for seal hunting until 1919 and has been a Tasmanian State Reserve since 1978. It was inscribed as a UNESCO World Heritage Site in 1997.
Macquarie Island is an exposed portion of the Macquarie Ridge and is located where the Australian Plate meets the Pacific Plate. The island is part of the Antipodes Subantarctic Islands tundra ecoregion. The Macquarie Ridge is a 1,600 km-long fault zone in the oceanic crust, running southwestwards from New Zealand along the plate boundary. The ridge lies entirely on the seafloor, except for where it rises above sea level at Macquarie Island.
The day-to-day management of the Macquarie Island Nature Reserve and World Heritage Area is the responsibility of the Tasmania Parks and Wildlife Service. The island has a research base that operates year-round, and it is a popular destination for tourists interested in wildlife and remote places.

The island is a UNESCO World Heritage Site
Macquarie Island is a UNESCO World Heritage Site. It was first nominated for inclusion on the World Heritage List in 1992 for its geological values, but the nomination was declined by the World Heritage Committee. It was subsequently nominated in 1996 and was successfully inscribed on the World Heritage List in 1997.
The island is a site of major geoconservation significance, being the only place on earth where rocks from the earth's mantle are actively exposed above sea level. These unique exposures include excellent examples of pillow basalts and other extrusive rocks, providing an exceptionally complete section of the structure and composition of both the oceanic crust and the upper mantle. The island is also the only island in the world composed entirely of oceanic crust and rocks from the mantle, deep below the earth's surface.
Macquarie Island is located about 1,500 km south-southeast of Tasmania, halfway between Tasmania and Antarctica. It is an oceanic island in the Southern Ocean, lying approximately halfway between Australia and the Antarctic continent. The island is the exposed crest of the undersea Macquarie Ridge, raised to its present position by the movement of the Indo-Australian tectonic plate meeting the Pacific plate. This process has been described as "the island itself seems to have been simply squeezed toward the surface like toothpaste from a tube".
The island is also home to vast congregations of wildlife, particularly penguins, during the breeding season. The breeding population of Royal Penguins, a species endemic to Macquarie Island, is estimated at over 850,000 pairs, one of the greatest congregations of seabirds in the world. The island also hosts a breeding population of King Penguins, estimated at around 150,000-170,000 pairs in 2000 and still expanding. Four species of albatross nest on the island's steep and rugged cliffs, along with impressive colonies of Elephant Seals during the breeding season.

It is the only known breeding ground of the royal penguin
Macquarie Island is a subantarctic island in the south-western Pacific Ocean, lying about halfway between New Zealand and Antarctica. It is governed as a part of Tasmania, Australia, and is the only known breeding ground of the royal penguin.
The island is home to the entire royal penguin population during their annual nesting season. The royal penguin (Eudyptes schlegeli) is a species of penguin found only on the sub-Antarctic Macquarie Island and adjacent islands. They inhabit the waters surrounding Antarctica and breed only on Macquarie Island and neighbouring islands.
Royal penguins breed in colonies that can be 1-2km inland, with birds following creeks into hillside colonies, up to 150m above sea level. The breeding season begins in September, with laying following in October. Typically, royal penguins lay two eggs, but only one usually survives. The egg is kept warm by both parents for around 35 days, with each parent taking 12-day shifts. After hatching, the male cares for the chick for 2 to 3 weeks, after which the female returns with food for both of them.
The royal penguin population on Macquarie Island was historically threatened by hunting for their oil. Between 1870 and 1919, the government of Tasmania issued licences for hunting them, with an average of 150,000 penguins being taken each year. Since the end of penguin hunting on Macquarie, the number of royal penguins has climbed to 850,000 pairs. However, modern threats to the royal penguin population on Macquarie Island include introduced predators such as rats and cats, plastic pollution, and decreased food supply due to commercial fishing.

Macquarie Island is a research base for meteorologic and geologic studies
Macquarie Island is an oceanic island in the Southern Ocean, lying about 1,500 km southeast of Tasmania, Australia. It is a part of the Macquarie Ridge, a 1,600-km-long fault zone in the oceanic crust, formed by the movement of the Indo-Australian and Pacific tectonic plates towards each other. The island is the only place on Earth where rocks from the Earth's mantle are being actively exposed above sea level. This unique geological feature provides an exceptionally complete section of the structure and composition of both the oceanic crust and the upper mantle.
The island is also an important global monitoring location for scientific research, including meteorological and geological studies. The Australian National Antarctic Research Expeditions (ANARE) have been using the base for scientific purposes since 1948. The research station, commonly called Macca, is a permanent Australian subantarctic research base managed by the Australian Antarctic Division (AAD). Scientific research on the island focuses on biology, geosciences, meteorology, and human impact on the environment.
The island is an important year-round observational site for the Bureau of Meteorology and Geoscience Australia in monitoring southern hemisphere climatic data. Macquarie Island is also a key site for the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) in detecting evidence of nuclear explosions as part of an international monitoring network.
In addition to meteorologic and geologic studies, Macquarie Island is also a site for biological research due to its large population of wildlife, including elephant seals and king penguins. Research on the island in recent years has focused on conservation and environmental management, investigating the long-term impacts of pest eradication programs on the island's ecosystem.
Overall, Macquarie Island serves as a significant research base for a range of scientific disciplines, contributing to our understanding of meteorology, geology, biology, and environmental conservation.

The island has a history of seal hunting
Macquarie Island, located in the southern ocean, is an external territory of Australia, governed as part of Tasmania. It is an exposed portion of the Macquarie Ridge, which is a tectonic plate boundary between the Australian and Pacific plates. The island is home to a diverse range of wildlife, including seals, penguins, and other seabirds.
The dangers and challenges of seal hunting in the Antarctic waters are evident from historical accounts. Sealers faced perilous journeys, harsh weather conditions, and the constant risk of injury or death. Despite the risks, the economic incentives for seal hunting remained strong until the market for seal oil began to dry up towards the end of the sealing era.
The psychological impact of seal hunting on the sealers themselves has also been explored, with some accounts suggesting that the violent nature of the hunts could have led to trauma and guilt among the participants. One notable account is that of Rallier du Baty, a "gentleman explorateur" from a well-off French family, whose sealing expedition occurred during a time when the market for seal oil was in decline. Du Baty's memoir provides insight into the emotional toll of seal hunting and the potential rationalizations involved in participating in such violent activities.
In 1911, the Australasian Antarctic Expedition established a small base and a radio relay station on Macquarie Island, marking the beginning of its transition from a hunting ground to a scientific research site. The relay station played a significant role in establishing communication links between Antarctica and Australia. Today, Macquarie Island is a UNESCO World Heritage Site, recognized for its unique geological features and ecological importance.
