Территория Эшмор и Картье: Австралийские острова в Индийском океане

External territory of Australia in the Indian Ocean

The Territory of Ashmore and Cartier Islands is an uninhabited Australian external territory consisting of four low lying tropical islands in two separate reefs (Ashmore and Cartier), as well as the territorial sea generated by the islands. Ashmore Reef is called Pulau Pasir by Indonesians and Nusa Solokaek in the Rotenese language. Both names have the meaning "sand island".

The territory comprises Ashmore Reef, which includes West, Middle and East Islands, in addition to two lagoons, as well as Cartier Reef, which includes Cartier Island. Ashmore Reef covers approximately and Cartier Reef , both measurements extending to the limits of the reefs. West, Middle and East Islands have a combined land area variously reported as , Cartier Island has a reported land area of .

According to Australian literature, Cartier Island was visited by Captain Nash in 1800, and named after his ship Cartier. Ashmore Island was seen by Captain Samuel Ashmore in 1811 from his ship Hibernia and named after him. Ashmore Island was annexed by the United Kingdom in 1878, as was Cartier Island in 1909. In December 1905, formally took possession of the Ashmore Islands on behalf of the United Kingdom. The ship's commander Captain Ernest Gaunt went ashore accompanied by five officers and around 200 seamen, erecting the Union Jack and singing "God Save the King", while Cambrian returned a 21 gun salute. After their annexation, the British Government occasionally granted licences on the islands for fishing or guano extraction. In the 1920s, the islands were used as a base for poachers targeting the Western Australian pearling industry. The lack of effective policing led to Australian lobbying for a transfer of control. A British order in council dated 23 July 1931 stated that Ashmore and Cartier Islands would be placed under the authority of the Commonwealth of Australia when Australia passed legislation to accept them, and formal administration began two years later. The Commonwealth's resulting Ashmore and Cartier Islands Acceptance Act 1933 came into operation on 10 May 1934, when the islands formally became a territory. The act authorised the Governor of Western Australia to make ordinances for the territory. In July 1938 the territory was annexed to the Northern Territory, then also administered by the Commonwealth, whose laws, ordinances and regulations applied to the Northern Territory. When self government was granted to the Northern Territory on 1 July 1978, administration of Ashmore and Cartier Islands was retained by the Commonwealth. In 1947, interior minister Herbert Johnson became the first Australian government minister to visit the territory. The Age reported that Johnson had been unable to land due to rough seas and regarded the islands as "almost valueless". In 1983, the territory was declared a nature reserve under the National Parks and Wildlife Conservation Act 1975, Cartier Island, which was a former bombing range, became a marine reserve in 2000. After the islands became a first point of contact with the Australian migration zone, in September 2001, the Australian Government excised the Ashmore and Cartier Islands from the Australian migration zone.

Today, the territory is administered from Canberra by the Department of Infrastructure, Regional Development and Cities, which is also responsible for the administration of the territories of Christmas Island, Cocos (Keeling) Islands, the Coral Sea Islands, Jervis Bay Territory and Norfolk Island. The Attorney General's Department had been responsible for the administration of Australian territories until the 2010 federal election. In that year the responsibility for Australian territories was transferred to the then Department of Regional Australia, Local Government, Arts and Sport, It has no permanently dry land area, although large parts of the reef become exposed during low tide.

The Northern Territory government has claimed on multiple occasions (1989, 1996) that the Ashmore and Cartier Islands should be returned to their jurisdiction, instead of remaining a separate territory. The Australian House of Representatives Standing Committee on Legal and Constitutional Affairs recommended in a 1991 report that the Northern Territory annex the islands. In 1998, John Howard's Coalition debated the issue in the leadup to the 1998 Northern Territory statehood referendum, and stated in a campaign release that it would "pursue incorporation of the Ashmore & Cartier Islands into the Northern Territory before or at the time of Statehood". However, these efforts did not lead to any changes.

The Ashmore Reef Marine Park and Cartier Island Marine Park are both classed as strict nature reserves (IUCN Ia) and protect biodiverse areas of significant and international importance, as well as cultural heritage. Cartier Island is an unvegetated sand island, The Australian Border Force vessel ABFC Thaiyak is stationed off the reef for up to 300 days per year. The islands are also visited by seasonal caretakers and occasional scientific researchers.

The area around the Ashmore and Cartier Islands has been a traditional fishing ground of Indonesian fishermen for centuries, and continues. In the 1850s, American whalers operated in the region. Once they had landed on Ashmore Island, asylum seekers could claim to have entered Australian migration zone and request to be processed as refugees. The use of Ashmore Island for this purpose created great notoriety during late 2001, when refugee arrivals became a major political issue in Australia. The Australian Government argued that as Australia was not the country of first asylum for these "boat people", Australia did not have a responsibility to accept them. A number of things were done to discourage the use of the Territory for this purpose, such as attempting to have the people smugglers arrested in Indonesia; the so called Pacific Solution of processing them in third countries; the boarding and forced turnaround of the boats by Australian military forces; and finally excising the Territory and many other small islands from the Australian migration zone. Two boatloads of asylum seekers were each detained for several days in the lagoon at Ashmore Island after failed attempts by the Royal Australian Navy to turn them back to Indonesia in October 2001.
