Dutch explorer.
In the service of the Dutch East India Company , he made exploratory and trading voyages to East and Southeast Asia (1634–39). In 1642 he was sent by Anthony van Diemen to find the hypothetical southern continent of the Pacific and a possible route to Chile. Sailing from Batavia (modern Jakarta), he reached 49k S at 94k E, then turned north and discovered land he named Van Diemen's Land (Tasmania), then sailed along the coast of New Zealand, believing it to be the southern continent. He also discovered Tonga and the Fiji Islands. On his next voyage (1644) he sailed into the Gulf of Carpentaria and along the northern and western coasts of Australia.
