Ashmore and Cartier Islands

The Territory of Ashmore and Cartier Islands [1] is an uninhabited external territory [2] of Australia consisting of four low-lying tropical islands in two separate reefs, and the 12-nautical-mile (22 km; 14 mi) territorial sea generated by the islands. [3] The territory is located in the Indian Ocean situated on the edge of the continental shelf, about 320 km (199 mi) off the northwest coast of Australia and 144 km (89 mi) south of the Indonesian island of Rote. [3]


Ashmore Reef is called Pulau Pasir by Indonesians and Nusa Solokaek in the Rotenese language. Both names have the meaning "sand island". [4]


The Territory comprises Ashmore Reef, which includes West, Middle, and East Islands, and two lagoons, and Cartier Reef, which includes Cartier Island. Ashmore Reef covers approximately 583 km2 (225.1 sq mi) and Cartier Reef 167 km2 (64 sq mi), both measurements extending to the limits of the reefs. [5]

West, Middle, and East Islands have a combined land area variously reported as 54 ha, 93 ha, and 112 ha (1 hectare is 0.01 km2, or about 2.5 acres). [6] [7] [8] Cartier Island has a reported land area of 0.4 ha. [7]


According to Australian literature [9] , Cartier Island was discovered by Captain Nash in 1800, and named after his ship Cartier. Ashmore Island was discovered by Captain Samuel Ashmore in 1811 from his ship HMS Hibernia and named after him. Ashmore Island was annexed by the United Kingdom in 1878, as was Cartier Island in 1909. [10]

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. 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[ which? ] laws, ordinances and regulations applied to the Territory[ which? ]. When self-government was granted to the Northern Territory on 1 July 1978, administration of Ashmore and Cartier Islands was retained by the Commonwealth. [3] [11]

In 1983 the territory was declared a nature reserve under the National Parks and Wildlife Conservation Act 1975, [3] now replaced by the Environment Protection and Biodiversity Conservation Act 1999. [12]

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. [3]

Indonesian heritage and memorandum

Ashmore has been regularly visited and fished by Indonesian fishermen since the early eighteenth century. A 1974 Memorandum of Understanding (MOU) between Australia and Indonesia sets out arrangements by which traditional fishers can access resources in Australia's territorial sea in the region. This allows traditional Indonesian fishermen to access parts of Ashmore for shelter, freshwater and to visit grave sites. The area, known as the MOU Box, contains the Ashmore and Cartier Islands Territory. [13]

Some Indonesian groups claim Ashmore Reef to be part of Rote Ndao Regency of East Nusa Tenggara province.[ citation needed ]


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. [14]

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, [3] and from 18 September 2013 the Department of Infrastructure and Regional Development has administered Australian territories.

Defence of Ashmore and Cartier Islands is the responsibility of Australia, with periodic visits by the Royal Australian Navy, Royal Australian Air Force and Australian Customs and Border Protection Service.

Nearby Hibernia Reef, 42 km (26 mi) northeast of Ashmore Reef, is not part of the Territory, but belongs to Western Australia. [15] It has no permanently dry land area, although large parts of the reef become exposed during low tide.

Environment and protection

There is no economic activity in the Territory, Ashmore and Cartier Islands being uninhabited. Cartier Island is an unvegetated sand island. [7] Access to Cartier Island is prohibited because of the risk of unexploded ordnances. There are no ports or harbours, only offshore anchorage. The customs vessel ACV Ashmore Guardian is stationed off the reef for up to 330 days per year. [16] The islands are also visited by seasonal caretakers and occasional scientific researchers.

The area has been a traditional fishing ground of Indonesian fishermen for centuries, and continues. In the 1850s, American whalers operated in the region. Mining of phosphate deposits took place on Ashmore Island in the latter half of the 19th century. [3] Today, all the wells in the Territory are infected with cholera or contaminated and undrinkable. [17]

Petroleum extraction activities take place at the Jabiru and Challis oil fields, which are adjacent to the Territory, and which are administered by the Northern Territory Department of Mines and Energy on behalf of the Commonwealth. [3]


As Ashmore Reef is the closest point of Australian territory to Indonesia, it was a popular target for people smugglers transporting asylum seekers en route to Australia. [18] 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.

The Australian migration zone is a legal device created by the Australian government for the purpose of Australia's visa policy and immigration policy, as the territory in which Australia’s visa policy applies. The Australian migration zone covers such Australian controlled territories as the government may determine. Prior to 2001, the Australian migration zone consisted of the mainland, and some external territories. Norfolk Island, for example, was not part of the Australian migration zone until 2016. Under Australia’s universal visa policy, a non-citizen must hold an Australian visa within the Australian migration zone. Without such a visa, or a bridging visa, the non-citizen is an unlawful non-citizen and treated as an “unauthorised arrival". However, the main impact of the migration zone is that unauthorised arrivals outside the zone have very limited access for review by Australian courts.

Sir Joseph Banks Group Conservation Park Protected area in South Australia

Sir Joseph Banks Group Conservation Park is a protected area in the Australian state of South Australia located on the Sir Joseph Banks Group in Spencer Gulf about 25 kilometres (16 mi) east-northeast of Port Lincoln. The conservation park of which specific islands had been previously declared as Flora and Fauna Reserves under statutes in force prior to 1972, was proclaimed in 1972 under the National Parks and Wildlife Act 1972. It was declared ‘primarily for the conservation of Cape Barren geese, and to protect marine mammal habitat’. As of 1996, the conservation park did not include Spilsby island which is privately owned and ‘lighthouse reserves’ on other islands while the following islands have been added post-declaration - Reevesby Island which was added in 1974 and Dangerous Reef which was added in 1989. The conservation park was subsequently extended to include the waters within 2 nautical miles (4 km) of the shoreline of all islands in the group and Dangerous Reef via a declaration under the National Parks and Wildlife Act 1972 for the purpose of regulating and managing great white shark berleying activities. The conservation park is classified as an IUCN Category Ia protected area.


The MOU Box, or sometimes the MOU 74 Box, refers to a rectangular tract of marine waters in the Timor Sea, lying within Australia’s Exclusive Economic Zone, that is subject to a 1974 memorandum of understanding, and subsequent agreements, between Australia and Indonesia.
