History:

Macquarie Island was discovered on July 11, 1810 by the Australian Frederick Hasselborough, who was looking for new grounds for the seal hunt. It proclaims British sovereignty over the island and the annex as a colony of New South Wales (The island gets its name from the then New South Wales governor, Colonel Lachlan Macquarie).

In 1890, New South Wales ceded the island to Tasmania, which entrusted it to Joseph Hatch. The latter used the island between 1902 and 1920 to exploit the penguins.

Between 1911 and 1914, the island became a base for Australia’s exploration of Antarctica. In 1911 George Ainsworth ran a weather station on the island. In 1933, the authorities made the island a sanctuary for wildlife based on the Tasmanian Animals and Birds Protection Act of 1928. In 1972 it was erected as a State Reserve.

Macquarie Island will be returned to its icy solitude in March 2017 with the closure of a scientific base permanently occupied by the Australians since 1948. The Australian Antarctic Division (AAD) justified Tuesday this decision by the aging of infrastructures And the too high costs of rehabilitation, due to the risks of environmental pollution and threats of submersion, with the base some meters above sea level.

Macquarie missions will continue to be possible due to the existence of six « cabins » that can accommodate visitors.

The whole is the emerged part of a chain and underwater fault. As a result, the region is subjected to powerful earthquakes (among the most powerful on earth).

Scientists today criticized the plan to eradicate hare cats that was carried out in order to preserve seabirds because it eventually favored the explosion of the rabbit population that ravaged the vegetation, which is essential for survival While insects have often lost their wings due to strong wind conditions.
