Eastern Australia was not discovered until 1770 and the Arctic and Antarctic areas were not heavily explored until the 19th century.any nations were looking for goods such as silver and gold but one of the biggest reasons for exploration was the desire to find a new route for the spice and silk trades. When the Ottoman Empire took control of Constantinople in 1453, it blocked European access to the area, severely limiting trade.
