The Tasmanian National Parks Association (NPA) wants Tasmanian Environment Minister to resign over her handling of the rabbit and rat infestation on Macquarie Island, off the southern coast of the state.
The call come after news of further delays and an $8 million blow-out in the projected cost of eradicating rabbits and rats, which are ruining the habitat of threatened species.
NPA president, Chris Bell, says the World Heritage-listed island is falling apart while the State Government keeps delaying.
"The Minister [Paula Wriedt ] should resign over this whole thing," he said.
"This is just a fiasco which has gone on long enough.
"She has had that plan on her desk for over 12 months and now the Tasmanian community is watching this sideshow of back and forward sort of blame games."
