 The Sweers Islands in van Van Diemen's Land (Tasmania) were named by Abel Tasman in November 1642, but the exact location of these islands remains unknown.Tasman also named 'Salomon Suwers (Sweers) hoeck' or Salomon Sweers Cape on the northern coast of Lavongai (New Hanover) in the Bismarck Archipelago, north-east of Papua New Guinea during the 1642 journey, and in 1644 Tasman named the Sweers River in the Gulf of Carpentaria, Queensland, Australia.This river's probable location is Investigator Road (in which case it was not a river), the strait between Bentinck and Sweers Island, two of the South Wellesley Islands.
