Tropical North Queensland is the northern part of Queensland, Australia, an area from about the city of Mackay north to the tip of Cape York. The tropical region of Queensland covers 54% of the state's area some 934,600 square kilometres (360,900 sq mi), and includes the whole area above the latitude 23.5 degrees south, taking in an area from Rockhampton north. However, what is generally accepted as Tropical "North" Queensland includes the cities of Mackay, Townsville and Cairns and the Australian islands of the Torres Strait. It also includes several world heritage listed areas, such as the Great Barrier Reef and the Wet Tropics.
