The Torres Islands are in the Torba Province of Vanuatu, the northernmost island group in the country. The chain of islands that make up this micro-archipelago straddle the broader cultural boundary that distinguishes Island Melanesia from several Polynesian outliers located in the neighbouring Solomon Islands. To the north is Temotu Province of the Solomon Islands, to the south Espiritu Santo, and to the southeast the Banks Islands. To the west, in the ocean, is the deep Torres Trench, the subduction zone between the Australian and Pacific Plates.
