Human habitation in Tasmania may date back some 58,000 years, at which time a land bridge existed between Tasmania and mainland Australia, connecting Flinders Island to Wilsons Promontory in Victoria. This land bridge formed as a result of a global drop in sea level during the ice ages which occur every 20,000 years or so. During this ice age, and possibly subsequent ones around 39-23 and 27-13 thousand years ago, aboriginal people may have travelled back and forth from Tasmania to the mainland. However, due to the long periods of isolation including the most recent 13,000 years, the Tasmanian Aboriginal people came to be distinctly different from those in the remainder of Australia.The Tasmanian aboriginals were almost entirely nomadic, but this should not characterize their society as simple. At the time of invasion by European settlers, There are thought to have been four to six thousand indigenous inhabitants, forming nine tribes that were further subdivided into eight or nine bands each. Each tribe was highly adapted to the spefic region they inhabited. The Tasmanians built rafts and catamarans to fish and travel, and had considerable skills in weaving and tool-making. Although they mainly travelled naked, the people used animal grease and ochre for adornment and to withstand the wet, cold winters, and made a variety of necklaces and sewn skins for further clothing nd adornment. Each tribe had well-defined territories and a unique language, and a complex set of trade routes connected the society as a whole.
These two ideologies finally clashed in the late 1960’s over the damming of Lake Pedder. This lake, set in the heart of the South-West, was a true jewel of the wilderness, complete with a beach of fine pink quartzite sand a quarter-mile wide. It was proposed to flood the lake and surrounding valley in order to construct Tasmania’s largest hydroelectric scheme of all. Those in power were quite unprepared for the public outcry by the new class of conservationists, who took their protest as far as the Federal government in attempts to save the lake. Eventually the scheme went ahead, and Lake Pedder is now "enlarged", but this conflict was significant as the beginning of environmentalism in Tasmania, and to some extent, Australia at large. It also resulted in the formation of the United Tasmania Group which can lay claim to being the world;s first environmental political party.
In the late 1970’s the Tasmanian government brought forht it’s next proposal, the "Gordon-below-Franklin scheme" to carry forth its mission of cheap power generation. This time experienced campaigners along with new initiates gathered to defend "Australia’s last Wild River", the Franklin. When worker’s moved to start construction, they were met by hundreds of protesters blockading the river in yellow rafts. A small guerilla war ensued with police and local residents searching the wilderness for protesters to be arrested, sometimes hundreds in a day, while in parliaments and courts the government and protest groups duelled back and forth over the scheme itself. The campaign went national, where a new Labour government was voted in on 1983, among other things promising to stop the dam by declaring the area World Heritage, thus bringing under Federal Authority. Ultimately the river was saved by a decision of Australia’s Highest Court, which found by 4-3 majority that the Federal Government’s actions were within Australia’s constituion.
The Franklim Dam debate was a defining moment for the state, and the nation. It represented a loud challenge to the doctrine of hydro-industrialisation and development-at-all-costs. It also produced a national environmental organisation called The Wilderness Society, which is one of Australia’s major players in green politics today. Finally it brought to Tasmania’s parliament the first "Green Independent", Bob Brown, who has gone onto lead a green party to Australia’s Federal Senate.
Tasmania in the 1980’s continued to be dominated by environmental politics, with other green indipendents joining Bob Brown, while theLiberal/Conservative Government was led by the soft-spoken but determined Robin Gray. In a windfall election in 1989, the green independents gained the balance of power in Tasmania’s parliament, the first green party in the world to hold sway in such a body. They entered into an accord with the then Labour Government under Michael Groom. This accord ultimately failed, and in subsequent elections the Greens have lost much of their power, but they remain an active force in Tasmanian politics, despite all predictions to the contrary.
