Hobart is the capital and most populous city of the island state of Tasmania, Australia. Located in Tasmania's south-east on the estuary of the River Derwent, it is the southernmost capital city in Australia. Despite containing nearly half of Tasmania's population, Hobart is the least-populated Australian state capital city, and second-smallest by population and area after Darwin if territories are taken into account. Its skyline is dominated by the 1,271-metre (4,170 ft) kunanyi / Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the seven local government areas that cover the city. It has a mild maritime climate.
