On this episode we will explore eco-expeditions in Queensland. southern sub-tropical rainforests of the Gold Coast hinterland, swims with dolphins at Seaworld, meets the local wildlife characters to the west of Cairns and relaxes in one of Australia’s lushest tropical paradises. Queensland, state of northeastern Australia, occupying the wettest and most tropical part of the continent. It is bounded to the north and east by the Coral Sea (an embayment of the southwestern Pacific Ocean), to the south by New South Wales, to the southwest by South Australia, and to the west by the Northern Territory. The capital is Brisbane, on the state’s southeastern coast. Queensland, the second largest of Australia’s states, occupies nearly one-fourth of the continent. The state is more than twice the size of the U.S. state of Texas and seven times larger than the United Kingdom. In terms of land occupancy, however, Queensland is indeed Australia’s largest state, with an occupied area greater than that of the whole of Western Australia. It also is the most decentralized mainland state, with most of its people scattered along the eastern coastline over a distance of 1,400 miles (2,250 km). The rest of the population is dispersed thinly over almost all of the vast interior, posing severe access and communication challenges. With its large area and small population, Queensland’s economy is essentially resource-based, its exports predominantly pastoral, agricultural, and mineral products. More than half of Queensland lies north of the Tropic of Capricorn, and the early Europeans there, unfamiliar with life in the tropics, experienced much adversity in their initial attempts to colonize the region. However, the climate, formerly a handicap, eventually became an advantage. In contemporary times Queensland—under the self-proclaimed title of the “Sunshine State”—has reaped the benefits of rapid growth in tourism, some attractions being sandy surfing beaches, verdant estuaries, picturesque islands, and the Great Barrier Reef, extending for 1,250 miles (2,000 km) off Queensland’s Coral Sea coastline. The state also experienced rapid population growth through “sunbelt” migration to the more attractive coastal regions, although the population in the already sparsely populated interior continued to decline. Area 668,207 square miles (1,730,648 square km). Population (2011) 4,332,739.
