Tasmania is an island state of Australia. It is located 240 kilometres (150 miles) to the south of the Australian mainland, separated from it by the Bass Strait, with the archipelago containing the southernmost point of the country. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 1000 islands. It is Australia's least populous state, with 569,825 residents as of December 2021. The state capital and largest city is Hobart, with around 40 percent of the population living in the Greater Hobart area.
1642 (MDCXLII) was a common year starting on Wednesday of the Gregorian calendar and a common year starting on Saturday of the Julian calendar, the 1642nd year of the Common Era (CE) and Anno Domini (AD) designations, the 642nd year of the 2nd millennium, the 42nd year of the 17th century, and the 3rd year of the 1640s decade. As of the start of 1642, the Gregorian calendar was 10 days ahead of the Julian calendar, which remained in localized use until 1923.
The maritime European exploration of Australia consisted of several waves of European seafarers who sailed the edges of the Australian continent. Dutch navigators were the first Europeans known to have explored and mapped the Australian coastline. The first documented encounter was that of Dutch navigator Willem Janszoon, in 1606. Dutch seafarers also visited the west and north coasts of the continent, as did French explorers.
The Tasman Sea is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about 2,000 km (1,200 mi) across and about 2,800 km (1,700 mi) from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who in 1642 was the first known person to cross it. British explorer Lieutenant James Cook later extensively navigated the Tasman Sea in the 1770s during his three voyages of exploration.
