Far North Queensland, or Tropical North Queensland, is the northernmost part of the state of Queensland, Australia. Centered on the city of Cairns, the region stretches north to the Torres Strait, and west to the Gulf Country. The region has Australia's only international border, with the independent nation of Papua New Guinea. The Far North region is the only region of Australia that is home to the two oldest continuous cultures on the planet, the Aboriginal Australians and the Torres Strait Islanders.
