Captain James Cook was the first to cross the Antarctic Circle, doing so in 1773. However, pack ice and the freezing of his ship's sails prevented him from reaching the Antarctic continent itself. The same thing happened when he again crossed the Antarctic Circle a year later.
If he found it to be uninhabited (terra nullius), he was simply to  take possession for His Majesty by setting up proper marks and inscriptions as first discoverers and possessors . In 1770, Captain Cook 'discovered' the south east coast of Australia, landing in Botany Bay. On 22 August 1770, he claimed the whole of the east coast of Australia at Possession Island, naming eastern Australia New South Wales.
