The Territory of Ashmore and Cartier Islands is an uninhabited Australian external territory consisting of four low-lying tropical islands in two separate reefs, as well as the 12-nautical-mile territorial sea generated by the islands. 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.

Rote Island is an island of Indonesia, part of the East Nusa Tenggara province of the Lesser Sunda Islands. According to legend, this island got its name accidentally when a lost Portuguese sailor arrived and asked a farmer where he was. The surprised farmer, who could not speak Portuguese, introduced himself, "Rote".
