Территория Островов Кораллового моря (Australia)

External territory of Australia

The Coral Sea Islands Territory is an external territory of Australia which comprises a group of small and mostly uninhabited tropical islands and reefs in the Coral Sea, north east of Queensland, Australia. The only inhabited island is Willis Island. The territory covers , most of which is ocean, extending east and south from the outer edge of the Great Barrier Reef and includes Heralds Beacon Island, Osprey Reef, the Willis Group and fifteen other reef/island groups. Cato Island is the highest point in the Territory.

The Coral Sea Islands were first charted in 1803. In the 1870s and 1880s the islands were mined for guano but the absence of a reliable supply of fresh water prevented long term habitation. and the Department of Transport and Regional Services. It is the only external territory not created by transfer from the United Kingdom or by the mandate of the United Nations. Defence is the responsibility of Australia, and the territory is visited regularly by the Royal Australian Navy. Australia maintains automatic weather stations on many of the isles and reefs, and claims a exclusive fishing zone. There is no economic activity (except for a significant but as yet unquantified charter fishing and diving industry), and only a staff of three or four people to run the meteorological station on Willis Island (South Islet), established in 1921. In November 2011, the Australian government announced that a protected area was planned in the Coral Sea. The Supreme Court of Norfolk Island has jurisdiction over the islands; however, the laws of the Australian Capital Territory apply. The territory's FIPS 10 4 code is CR, whereas ISO 3166 includes it in Australia (AU). In June 2004, a symbolic political protest run by gay rights activists based in Australia, declared the Coral Sea Islands to be a sovereign micronation. On 17 November 2017 the same group declared the kingdom to be 'dissolved', following the results of the Australian Marriage Law Postal Survey.

Mellish Reef, being about 300 km to the east of the Northwestern Group, thus the most distant from the Australian continent of all the reefs and atolls of the Coral Sea Islands Territory, is not considered to be part of any group. It has the outline of a boomerang shaped platform around 10 km in length and 3 km across, area 25 km2. The surrounding reefs, which enclose a narrow lagoon, are completely submerged at high tide. Near the centre of the lagoon is the only permanent land of the reef Heralds Beacon Islet. The island is a small cay measuring 600 m by 120 m, area 57,000 m2, only rising a few ms above the high water mark. The reef was discovered and named by Captain Alexander Bristow in the whaling ship Thames on 5 April 1812. The French aviso Duroc wrecked on the reef on 16 August 1856. erected the first beacon on the cay, using wreckage from Duroc.

Elizabeth and Middleton reefs, together with reefs around Lord Howe Island (New South Wales) 150 km to the south, are regarded as the southernmost coral reefs in the world. Their location, where tropical and temperate ocean currents meet, contributes to an unusually diverse assemblage of marine species. These mostly submerged atolls which dry only during low tide were added to the territory only in 1989. They are located on the Lord Howe Rise. Already on 23 December 1987, they were protected as the Elizabeth and Middleton Reefs Marine National Park Reserve, which has an area of 1,880 km2. Elizabeth Reef, atoll about 8.2 km by 5.5 km, area 51 km2 including lagoon, one islet: Elizabeth Island (Elizabeth Cay), no vegetation, 600 m by 400 m (area 0.2 km2), highest point 0.8 m. At low tides, much of the reef flat is exposed. Middleton Reef, atoll about 8.9 km by 6.3 km, area 37 km2 including lagoon, one islet: The Sound, 100 m by 70 m (area 5,000 m2), highest point 1.5 m (close to the northern end). At low tides, much of the reef flat is exposed.
