High Quality Content by WIKIPEDIA articles! Queensland is a state of Australia that occupies the north-eastern section of the mainland continent. It is bordered by the Northern Territory to the west, South Australia to the south-west and New South Wales to the south. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. The state is Australia's second largest by area, following Western Australia, and the country's third most populous after New South Wales and Victoria. The area was first occupied by Indigenous Australians and Torres Strait Islanders, who arrived between 40,000 and 65,000 years ago, according to various dating methods. Later, Queensland was made a British Crown Colony that was separated from New South Wales on 6 June 1859, a date now celebrated annually as Queensland Day.
