Tasmania State flag, Commonwealth of Australia

Tasmania is an island state of Australia. It is located 240 kilometres (150 miles) to the south of the Australian mainland, and is separated from it by the Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 1000 islands. It is Australia's smallest and least populous state, with 573,479 residents as of June 2023. The state capital and largest city is Hobart, with around 40% of the population living in the Greater Hobart area. Tasmania is the most decentralised state in Australia, with the lowest proportion of its residents living within its capital city. Tasmania's main island was first inhabited by Aboriginal peoples, who today generally identify as Palawa or Pakana. It is believed that Aboriginal Tasmanians became isolated from mainland Aboriginal groups around 11,700 years ago, when rising sea levels formed Bass Strait. In 1803, Tasmania was permanently settled by Europeans as a penal settlement of the British Empire, partly to pre-empt French territorial claims during the Napoleonic Wars. At the time of British arrival, the Aboriginal population is estimated to have been between 3,000 and 7,000. Within three decades, however, this number declined drastically due to violent conflict, known as the Black War, and the spread of infectious diseases. The Black War peaked between 1825 and 1831, resulting in the declaration of martial law for more than three years and causing the deaths of nearly 1,100 Aboriginal people and settlers. Under British rule, the island was initially part of the Colony of New South Wales; however, it became a separate colony under the name Van Diemen's Land (named after Anthony van Diemen) in 1825. Approximately 80,000 convicts were sent to Van Diemen's Land before this practice, known as transportation, ceased in 1853. In 1855, the present Constitution of Tasmania was enacted, and the following year the colony formally changed its name to Tasmania. In 1901, it became a founding constituent state of Australia (one of six) through the process of the federation of Australia. Today, Tasmania has the second smallest economy of the Australian states and territories; economic activity involves principally tourism, agriculture, aquaculture, education, and healthcare. Tasmania is a significant agricultural exporter, as well as a significant destination for eco-tourism. About 42% of its land area, including national parks and World Heritage Sites (21%), is protected in some form of reserve. The first environmental political party in the world was founded in Tasmania.
