The Bassian Plains allowed Aboriginal people to travel from the mainland to Tasmania.
Aboriginals have been in what is now known as Tasmania for at least 35,000 years. It is believed that they crossed over into Tasmania via a land bridge, known as the Bassian Plains, which formed between Tasmania and modern day Victoria during the Last Glacial Maximum (LGM).
Up until about 12,000 years ago this land bridge allowed both seasonal and permanent habitation of Tasmania, which at that point was far larger and had a vast wealth of resources. Around 12,000 years ago the land bridge started receding as a result of the end of the LGM. Water levels rose about 120 metres and the Aboriginal people became cut off for over 10,000 years, becoming the longest isolated group in history.
