Hogan Island, the largest island of the

Together with the other islands in the Hogan, Kent and Furneaux groups, Hogan Island formed part of a land bridge that connected Tasmania to mainland Australia until the end of the Pleistocene period. After the glacial period ended, the Hogan Group were the first islands to become isolated by rising sea levels.^[2]

The state border between Tasmania and Victoria lies in the Hogan Group and passes over land on the North East Islet, thus giving a land border between the two states. Before Victoria became a colony, it was agreed that New South Wales would have the sovereignty of all the land to Bass Strait, and Tasmania would have Bass Strait, except for waters near the coast. The original intention was that these Bass Strait Islands would be part of Tasmania, but the surveyed position for Wilson's Promontory was slightly off, and the border placed too far south at 39°12' S. Once this was discovered the Islet was renamed to Boundary Islet. The land border is 85 metres (279 ft) long.^[4][5]
