The Furneaux Islands are visible reminders of the land bridge that once connected Tasmania to mainland Australia until the end of the last Ice Age about 12,000 years ago. Flinders is the largest and best known of the group.
Badger Island has geoconservation significance due to its limestone pavement and granite intrusions, which are considered representative and outstanding for Tasmania. The island is 1,242 hectares (about 3,000 acres) and is extensively grazed by cattle, sheep, Bennetts wallabies and pademelons. Buildings include a homestead, shed, windmill and extensive jetty.
