The Torres Strait, also known as Zenadh Kes, is a strait between Australia and the Melanesian island of New Guinea. It is 150 km (93 mi) wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606.

Captain James Cook was a British explorer, cartographer and naval officer famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands and the first recorded circumnavigation of New Zealand.
