The Australian Greens Leader, Tasmanian Senator Christine Milne has welcomed the extended moratorium on fracking but says Tasmanians need the certainty of a permanent ban.
"We need to send a signal now to all the companies involved, and the financial institutions behind them, to say we are never going to allow fracking in Tasmania, full stop, it is over," said Senator Milne.
"Farmers are going to be worried sick that while the public has been calmed down thanks to this moratorium, everything is actually business as usual behind the scenes.
"The temporary moratorium just lets the companies keep exploring, keep working on their licences, then when the five years is up hoping that they'll be able to proceed.
"Farmers need to be sure they can farm their land and look after their water without having this risk lurking in the back rooms," said Senator Milne.
"Tasmania's huge competitive advantage in this century is in renewable energy and in our agricultural land and water.
"I can't emphasise enough that in an age of global warming, where food security is a big issue, agricultural land and water are gold. You do not destroy them with fracking, and that's why there should be a ban."
