Hean was one of the early campaigners against the flooding of
Lake Pedder in the Tasmanian Wilderness. "The real driving force behind the LPAC was Brenda Hean...she always raised Lake Pedder, and they said 'It's nothing to do with us.' But she said 'Yes it is, because it's your conscience." "She sat upon a block of
quartzite which had been etched by the weather and was ornamented by a patchwork of moss and lichen. Her chin was thrust defiantly forward. As she gazed across the lake she seemed to become one with it, and both of them seemed to become part of something greater."
Eric Reece and the
Hydro-Electric Commission's disinterest in complaints as to their manner of dealing with opposition to their plans gave the impression that they ran Tasmania without any checks. Hean then decided to run for politics as a member of the
United Tasmania Group, the world’s first green party. Hean and Price were trying to widen the scope of the opposition in mainland Australia, in a way that the subsequent
Franklin Dam protest did some ten years later. == Disappearance ==
