トレス海峡諸島
The Melanesian background of the Thursday Islanders became an issue in the 1970s, when Papua New Guinea sought to include some of the Torres Strait Islands within its borders. The Torres Strait Islanders insisted that they were Australians, however, and after considerable diplomatic discussion and political disputation between the Queensland and the Federal Governments, all of the Torres Strait islands, including Thursday Island, remained part of Australia.
