The distance between Tasmania and the closest point on the Australian mainland is around 150 miles. Tasmania is an administrative state of Australia, and is isolated from the mainland by the Bass Strait, a shallow channel that is dotted by numerous islands.
Formerly known as "Van Diemen's Land" after the Dutch governor, Anthony van Diemen, the state's present name of "Tasmania" is derived from the Dutch explorer Abel Janszoon Tasman. The island's terrain is predominantly mountainous and characterized by vast regions of wilderness and national parks. Tasmania's Museum of Old and New Art, popularly known as MONA, is one of Australia's most unconventional and controversial art galleries.
