geography Maturity 11-13 Next article →

The Torres Strait is a vital maritime passage located between Australia and the island of New Guinea.

To the south sits the Cape York Peninsula, which is the northernmost part of the Australian mainland. To the north lies the Western Province of Papua New Guinea. This strait serves as a critical link between the Coral Sea to the east and the Arafura Sea and Gulf of Carpentaria to the west.

While it is a major international sea lane, the area is difficult to navigate. The water is very shallow, and the region contains a complex maze of reefs and islands. Strong tidal currents move through narrow channels between these landforms. Additionally, large submarine sand dunes migrate across the seafloor, creating a constantly changing environment.

The geography of the strait is defined by its incredible variety of landforms. There are at least 274 islands within the Torres Strait, though only 17 have permanent settlements today.

These islands formed in different ways. The islands closest to New Guinea are low-lying. They were created by alluvial sedimentary deposits, which are sediments carried by river outflows into the sea. The western islands are steep and hilly. These are actually the northernmost peaks of the Great Dividing Range. They became islands when sea levels rose at the end of the last ice age. The central islands are mostly coral cays, while the eastern islands are of volcanic origin. The region also hosts some of the most extensive seagrass beds in the world, and approximately 580 coral reefs cover the area.

Human history in the strait is ancient and deeply connected to the sea. Indigenous people have inhabited the islands for at least 2,500 years, and perhaps much longer. The Torres Strait Islanders possess a unique culture that is ethnically distinct. They are related to both the Aboriginal Australians and the Papuans of New Guinea, but they are separate from both groups. For thousands of years, maritime-based trade has allowed for cultural diffusion between these three societies. The islanders speak indigenous languages such as Kala Lagaw Ya and Meriam Mir. Many people also speak Torres Strait Creole, also known as Brokan. In the 1980s, local people adopted the name Zenadh Kes for the region. This name is an acronym derived from words meaning south, north, place, coastline, and waterway.

European contact with the strait began with the Spanish navigator Luís Vaz de Torres. In 1606, Torres sailed through the passage as a pilot for an expedition led by Pedro Fernandes de Queirós. Although Torres discovered the strait, early Spanish maps often omitted Australia. It was not until 1769 that the Scottish geographer Alexander Dalrymple found Torres's testimony in the Philippines. Dalrymple used this information to prove a passage existed south of New Guinea. He eventually named the area the "Torres Straits" on official British maps. This discovery later enabled James Cook to chart the eastern coastline of Australia in 1770.

Cook landed on Possession Island and signaled that the passage was navigable.

Other explorers contributed significantly to the maritime knowledge of the region. In 1823, Captain John Lihou navigated a 550-ton merchant ship from west to east through the strait. This was a remarkable feat of nautical skill that resulted in the loss of four anchors and a rudder. During this voyage, Lihou discovered the Lihou Reef and Cays, as well as Port Lihou. He also named the Saumarez Reefs after Vice-Admiral James Saumarez. Later, the region became famous for a massive pearling industry. From the 1860s until its collapse around 1970, pearl-shelling drove the local economy. This industry brought experienced divers to the islands from many different countries, including Japan.

Modern management of the strait requires cooperation between nations. Because the strait is shared, Australia and Papua New Guinea signed the Torres Strait Treaty in 1985. This agreement establishes maritime boundaries and defines sovereignty. It also creates a Torres Strait Protected Zone to manage fisheries and protect habitats. The treaty ensures that the traditional way of life for the islanders is supported. Today, officials must also manage environmental risks, such as mining waste from the Fly River in Papua New Guinea. The treaty helps both nations share commercial and traditional fishing resources while protecting the biodiversity of the region.

The cultural legacy of the islands continues to be studied by researchers. Anthropologists have visited the islands since at least 1898 to document unique traditions. Margaret Lawrie conducted extensive research between the 1950s and 1970s. She collected oral stories, photographs, and artworks from the local people. Her work formed the basis of books like "Tales from Torres Strait." In 2008, her collection was added to UNESCO's Australian Memory of the World Register. This recognition highlights the importance of the Torres Strait Islander's history and their enduring connection to these waters.
