Brenda Hean

"[3]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.

[4] She then planned a protest flight to Canberra with Max Price, from Tasmanian Aviation Services, in a WW2 era Tiger Moth to gain support by skywriting 'Save Lake Pedder' above Parliament House.

[5][6] 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.

It was suspected that pro-dam campaigners had broken into the plane's hangar the night before it took off and placed sugar in one of its petrol tanks.
