Great Bay is a rural locality on Bruny Island in the local government area of Kingborough in the Hobart region of Tasmania. It is located about north-east of the town of Alonnah, the largest town on the island. The 2016 census determined a population of 57 for the state suburb of Great Bay.[1] The Bruny Island Airport is located within the suburb of Great Bay.
Great Bay is a confirmed suburb/locality.[2] In 1829 the Protector of Aborigines, George Augustus Robinson, set up an Aboriginal settlement near Great Bay (the body of water) on Bruny Island. It was here that Truganini first met Robinson.[3]
The D'Entrecasteaux Channel forms the western boundary. This includes the southern half of Great Bay (the body of water).
The B66 route (Bruny Island Main Road) enters from the north and runs through to the south before exiting.[2] [4]
