The Hogan Group is a collection of 6 islands and islets in the Bass Strait in between mainland Australia and the island state of Tasmania.
Within the jurisdiction of Tasmania, the Hogan Group forms a land border between the states of Tasmania and Victoria. The island group is officially designated unallocated Crown land.[2]
Location and geography
The Hogan Group is located 40 kilometres (25 mi) southeast of Wilsons Promontory in the Bass Strait. The islands are made up of gray and red granite and limestone. A group of fur seals lives on Boundary Islet. Other plants and animals that live on and near the island group include Cystophora intermedia, eelgrass, kelp, and abalone.[1]
History
During the Pleistocene 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.[3]
The Hogan Group was discovered and named in 1801 by John Black, captain of the 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.[3] 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.[3]
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.[4]
