Bass visited the Kiama area and made many notes on its botanical complexity and the amazing natural phenomenon, the Kiama Blowhole, noting the volcanic geology around the Blowhole and contributed much to its understanding. Circumnavigation of Tasmania in the Norfolk In 1798, this theory was confirmed when Bass and Flinders, in the sloop Norfolk, circumnavigated Van Diemen's Land. In the course of this voyage Bass visited the estuary of the Derwent River, found and named by Captain John Hayes in 1793, where the city of Hobart would be founded on the strength of his report in 1803. When the two returned to Sydney, Flinders recommended to Governor John Hunter that the passage between Van Diemen's Land and the mainland be called Bass Strait. "This was no more than a just tribute to my worthy friend and companion," Flinders wrote, "for the extreme dangers and fatigues he had undergone, in first entering it in a whaleboat, and to the correct judgement he had formed, from various indications, of the existence of a wide opening between Van Diemen's Land and New South Wales." Bass was an enthusiastic naturalist and botanist, and he forwarded some of his botanical discoveries to Sir Joseph Banks in London. "In this voyage of fourteen weeks I collected those few plants upon Van Diemen's Land which had not been familiar to me in New South Wales," he wrote to Banks, "and have done myself the honour of submitting them to your inspection." He was made an honorary member of the Society for Promoting Natural History, which later became the Linnean Society. Some of his observations were published in the second volume of David Collins's An Account of the English colony in New South Wales. He was one of the first to describe the Australian marsupial, the wombat. Marriage and trading On 8 October 1800, George married Elizabeth Waterhouse at St James's Church, Westminster. She was the sister of Henry Waterhouse, Bass's former shipmate, and captain of the Reliance. In January 1801 Bass set sail again for Port Jackson, leaving Elizabeth behind, and though the couple wrote to each other, they did not meet again, as Bass never returned from this journey. Bass and a syndicate of friends had invested some £10,000 in the copper-sheathed brig , and a cargo of general goods to transport and sell in Port Jackson. Bass was the owner-manager and set sail in early
