period, the Hogan Group was part of a land bridge that connected Tasmania to mainland Australia. After the glacial period ended, the Hogan Group were the first group of islands to become isolated by rising sea levels. The Hogan Group was discovered by Europeans and named in 1801 by John Black, captain of the brig '' Harbinger'', who named the island group after Michael Hogan, the owner of his ship. There are records of settlers on the island group, who hunted seals and kangaroos and used the islands for grazing land. On 12 October 1900, the first lease was recorded and given for Hogan Island. While the original lease covered the entire island group, since 1959 the lease has only applied to Hogan Island, which has been leased by B.R. Stackhouse since 1967, who uses the island for sheep and cattle grazing. Black erred in his initial survey, placing the group further north than they actually are, which led to the Victoria-Tasmania land border on Boundary Islet.
