Coordinates: 23°0′S 143°0′E / 23°S 143°E / -23; 143 Queensland is the second-largest and third-most populous state of Australia, located in the northeast of the country. It is bordered by the Northern Territory, South Australia and New South Wales to the west, southwest and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. Queensland has a population of 4,580,700, concentrated along the coast and particularly in the state's South East. The state is the world's sixth largest subnational entity, with an area of 1,852,642 km2. The capital and largest city in the state is Brisbane, Australia's third largest city. Referred to as the 'Sunshine State', Queensland is home to 10 of Australia's 30 largest cities and is the nation's third largest economy.

Queensland was first occupied by Indigenous Australians and Torres Strait Islanders, who arrived at least 40,000 years ago. The first European to land in Queensland was Dutch navigator Willem Janszoon in 1607. In 1770, Lieutenant James Cook claimed the east coast of Australia for the Kingdom of Great Britain. The colony of New South Wales was founded in 1788 by Governor Arthur Phillip at Sydney; New South Wales at that time included all of what is now Queensland, Victoria and Tasmania. Queensland was explored in subsequent decades until the establishment of a penal colony at Brisbane in 1824 by John Oxley. Penal transportation ceased in 1839 and free settlement permitted in 1842. Queensland was separated from New South Wales, forming a self-governing colony, on 6 June 1859, a date now celebrated state-wide as Queensland Day. Queensland achieved statehood with the Federation of Australia on 1 January 1901.

North Queensland or the Northern Region is the northern part of the state of Queensland in Australia. Queensland is a massive state, larger than many countries, and the tropical northern part of it has been historically remote and undeveloped, resulting in a distinctive regional character and identity.

Townsville is the largest urban centre in North Queensland, leading it to be regarded as an unofficial capital^{[citation needed]}. The region has a population of 231,628 and covers 80,041.5 km².

There is no official boundary that separates North Queensland from the rest of the state. Unofficially it is usually considered to have a southern border beginning south of the Mackay Region southern boundary, but historically it has been as far south as Rockhampton. To the north is the Far North Queensland region, centred around Cairns and out west is the Gulf Country.

A coastal region centred around its largest settlement is the city of Townsville. The city is the location of a major seaport handling exports from mines in Mount Isa and cattle exports from coastal and inland areas. The region also contains a bulk sugar exporting terminal at Lucinda in the region's north. Mackay is Australia's sugar capital and produces the most sugar in Australia and is shipped at Mackay Harbour. Mackay is also one of Australia's biggest coal exporters as it is close to Queensland's major mines. Dalrymple Bay, south of Mackay is another port where coal and sugar is exported. It also contains the inland city of Charters Towers and the coastal towns of Ayr and Ingham.
