Cocos (Keeling) Islands

The Cocos (Keeling) Islands are tiny coral islands in the Indian Ocean. Most of the plants are coconut palms. They belong to Australia.

The Cocos (Keeling) Islands are an Australian territory in the eastern Indian Ocean, made of two coral atolls. Most people are Cocos Malays who live on Home Island, and the land is so low that the highest point is only about 6 meters above the sea. The 2021 census counted 593 people.

The Cocos (Keeling) Islands, an external territory of Australia 3,685 km west of Darwin, are two coral atolls: the southern ring of 26 islets around South Lagoon and lone North Keeling Island, now Pulu Keeling National Park. Most residents are Cocos Malays on Home Island; the 2021 census counted 593 people.

Discover the Cocos (Keeling) Islands

The Cocos (Keeling) Islands are far out in the Indian Ocean.

There are two rings of coral islands. Palm trees grow on them.

The Cocos (Keeling) Islands lie in the eastern Indian Ocean, about 3,685 kilometers west of Darwin, Australia, and about 900 kilometers southwest of Christmas Island. They are made of two coral atolls. The southern atoll has 26 islets around a lagoon, and the northern one is a single island, North Keeling.

The islands are an external territory of Australia, and an administrator is appointed by Australia's governor-general. The administrative headquarters is on West Island, and people pay with the Australian dollar.

Britannica places the territory 3,685 km west of Darwin and about 900 km southwest of Christmas Island: two coral atolls, the southern with 26 islets and the northern containing only North Keeling Island, 14 km² of land in all. The administrative headquarters is on West Island.

The islands became an Australian territory under the Cocos (Keeling) Islands Act 1955. An administrator appointed by the governor-general is the senior official; the Territories Law Reform Act 1992 applied Western Australia's legal structure and created a Shire Council for most local services, and islanders vote in the federal electorate of Lingiari.

Home Island, West Island and the lagoon

Most people live on Home Island.

West Island has the airport and long white beaches.

The southern atoll's main islands are West Island, the largest at about 10 kilometers long, and South, Home, Direction and Horsburgh islands, around South Lagoon. At the 2021 census, 432 people lived on Home Island and 147 on West Island.

The photo shows a beach on West Island at sunset, with palm trees, gentle waves and a pink and purple sky. Flights link the islands with Perth and with Christmas Island.

West Island, 10 km long, is the largest island in the territory; the other main South Keeling islands are South, Home, Direction and Horsburgh, around South Lagoon. The 2021 census counted 432 people on Home Island (Bantam Village) and 147 on West Island; Britannica describes West Island's residents as mostly mainland-recruited staff of the territory administration and their families.

An airstrip built on West Island in 1945 served flights between Perth and Johannesburg until 1967; regular passenger flights now connect the islands with Perth and Christmas Island. The photo shows a West Island beach at sunset.

Low coral islands and a turquoise lagoon

The islands are very low, just a little above the sea.

The lagoon water is clear and blue. Most of the plants are coconut palms.

The Cocos (Keeling) Islands are made of coral, and the land is very low: the highest point is only about 6 meters above sea level. It is warm and humid, from 25 to 29 °C, and about 1,970 millimeters of rain falls in a year. Cyclones sometimes strike early in the year.

Most of the plants are coconut palms. In 1836 the English naturalist Charles Darwin studied the islands' coral reefs.

Britannica describes low coral islands rising only about 6 m above sea level, with North Keeling about 24 km north of South Lagoon. The climate is warm and humid (25 to 29 °C) with about 1,970 mm of rain a year; destructive cyclones may strike early in the year, and earthquakes occur periodically.

Vegetation is chiefly coconut palms, formerly cultivated for copra on plantations, with coarse grass on North Keeling and Horsburgh. Charles Darwin made observations of the coral reefs here in 1836, and meteorological reports from the islands help forecast weather for a large area of the Indian Ocean.

Pulu Keeling's seabirds

Tens of thousands of seabirds nest on North Keeling Island.

Land crabs scuttle across the sand.

There are no native mammals on the islands, but seabirds and land crabs are plentiful. North Keeling Island and the waters around it became Pulu Keeling National Park in 1995. Tens of thousands of seabirds breed there, including one of the most important colonies of boobies in the world.

Parks Australia says the land of the park belongs to the Cocos Malay people, but the seabirds are its real rulers. The park is hard to reach, and its reefs and sea life are thriving.

Britannica notes there are no indigenous mammals, while seabirds and land crabs abound. North Keeling Island and its surrounding waters were designated Pulu Keeling National Park in 1995 for rare ecosystems, including an intact coral atoll environment, and a notable seabird breeding ground.

Parks Australia describes tens of thousands of breeding seabirds on North Keeling, including one of the most important booby colonies on Earth, reefs surrounding a thriving marine ecosystem, and land that belongs to the Cocos Malay people. The park is untouched and difficult to reach.

The Cocos Malay community

Most people on the islands are Cocos Malays.

They speak a kind of Malay. Many families live on Home Island.

Most islanders are Cocos Malays, descendants of plantation workers, mostly of Malay origin, who were brought to the islands from 1827. Most speak a dialect of Malay, and at the 2021 census more people spoke a language other than English at home than spoke English.

In the 1950s many Cocos Islanders moved to mainland Australia, mostly to Western Australia, because the islands had become crowded. In 1984 the islanders voted to join fully with Australia.

Britannica describes the inhabitants as predominantly descendants of the original plantation workers, mostly of Malay origin, brought by the Scotsman John Clunies-Ross in 1827 to 1831; most Cocos Malays speak a dialect of Malay and are Muslim. At the 2021 census, 381 residents spoke a language other than English at home and 113 English.

Many Cocos Islanders moved to the mainland in the mid-1950s because of overcrowding, settling mainly in Western Australia. In 1979 Home Island residents set up the Cocos Islands Council, and in a 1984 referendum they voted for full integration with Australia. The ABS estimated 603 residents in June 2021; the census that August counted 593.

Coconut plantations to an Australian territory

Long ago, no one lived on these islands.

Later, families came to work with the coconut palms. Today the islands belong to Australia.

No one lived on the islands when the English sailor William Keeling saw them in 1609. In 1827 the Clunies-Ross family settled there and brought Malay workers to harvest coconuts. Charles Darwin visited in 1836.

Britain claimed the islands in 1857, and they were linked to Ceylon, then the Straits Settlements and Singapore. In 1955 they passed to Australia. In 1978 the Clunies-Ross family handed its authority to Australia, and in 1984 the islanders voted to join fully with Australia.

Uninhabited when William Keeling of the East India Company sighted them in 1609, the islands were first settled in 1826 by Alexander Hare; in 1827 John Clunies-Ross arrived, improved the coconut groves and brought in Malay workers to harvest copra. Charles Darwin studied the reefs in 1836.

Declared British in 1857, the islands were placed under Ceylon (1878), attached to the Straits Settlements and granted in perpetuity to the Clunies-Ross family (1886), and attached to Singapore (1903). They passed to Australia in 1955. In 1978 John Clunies-Ross sold most of his property and gave up his authority; islanders voted for integration in 1984, and the family sold its remaining Home Island property in 1993.

Through the years

The Cocos (Keeling) Islands on the map

Find the Indian Ocean on the globe.

Look far west of Australia and southwest of Christmas Island. The tiny dots there are the Cocos (Keeling) Islands.

The Cocos (Keeling) Islands lie about 12 degrees south of the equator in the Indian Ocean, about 3,685 kilometers west of Darwin. Christmas Island is about 900 kilometers to the northeast.

The islands are too small for the globe to draw, so PlayOwl marks them with dots: West Island, Home Island, Direction Island, Horsburgh Island and North Keeling.

West Island lies at about 12.19° S, 96.83° E; North Keeling is about 24 km north of South Lagoon. Christmas Island lies about 900 km to the northeast. The territory has no land borders.

At the globe's scale the atolls have no outlines, so the map uses markers: West Island, Home Island, Direction Island, Horsburgh Island and North Keeling (Pulu Keeling National Park).
