A senior Federal Labor MP warns the Greens will walk away from Tasmania's minority government and blame Labor for its demise.
Federal Labor MPs and the Greens have been trading blows since the, announced on Tuesday her party's relationship with the Government was effectively over.
Tasmania's Premier, Lara Giddings and acting Tasmanian Greens leader Tim Morris say the federal rift will not destabilise the Tasmanian power-sharing arrangement with Labor.
But long-serving MP Dick Adams says the State Government needs to be careful in its dealings with the Greens.
"The state Labor Party here will want to be very careful because I should imagine the Greens will do exactly the same as what they're doing to Federal Labor," he said.
"We've just seen what they've done here, they've walked away from other agreements in the past, this seems to be their tactic."
"State Labor ought to be very conscience of that."
In ending the federal Greens deal, Senator Milne cited a string of Government decisions, including its refusal to redesign the mining tax and nominate Tasmania's Tarkine region for national heritage listing.
But Premier Lara Giddings says her agreement with the Greens is solid.
She told the National Press Club on Wednesday it was difficult to draw comparisons with the federal arrangement.
"Julia Gillard didn't just have the Greens to form a relationship with; she had Andrew Wilkie, of course, and Rob Oakshott and other individuals in the Parliament," Ms Giddings said.
"So it's not as easy to make a direct parallel between what we have done and what she has done."
The Premier says Tasmanian Labor's alliance with the minority party differs from Federal Labor's.
"We have two Green ministers in our Cabinet, they hold the responsibility and power of Government, they have to conduct themselves appropriately and responsibly as Cabinet ministers.
"They also know the power of stability and we're determined to show that minority government can be stable."
But state Opposition Leader Will Hodgman is not expecting a political divorce anytime soon.
"They're joined at the hip, they are very much a coalition."
