A massive 10 per cent swing statewide against the former federal government has claimed Labor incumbents Geoff Lyons in Bass and Sid Sidebottom in Braddon and looks set to oust Dick Adams in Lyons.

The Liberals primary vote soared to 40 per cent in the lower house across the state, delivering decisive victories to former army brigadier Andrew Nikolic in Bass and former state Liberal MP Brett Whiteley in Braddon.

The swing towards the Liberals was felt strongest in Lyons where they improved on their 2010 result by 14 per cent on a two-party preferred basis.

However, Mr Adams was not conceding defeat last night with his Liberal opponent Eric Hutchinson in front 51.75 per cent on a two-party preferred basis with postal votes still to be counted.

In the South, independent Andrew Wilkie has retained his seat, increasing his margin to 15 per cent.

That leaves Franklin MHR Julie Collins as likely the only Labor representative in the state.

Tasmanian Liberal Senator David Bushby was celebrating victory last night.

"Tasmania has done its bit to deliver the change that we needed," Senator Bushby said.

The Greens were smashed in the lower house with their primary vote halved, while the new Palmer United Party surpassed expectations picking up 6 per cent.

Greens leader Christine Milne tipped the vote would bounce back.

"There will be a correction after this when people wake up tomorrow, realise Tony Abbott is prime minister and recalibrate what that actually means," Senator Milne said.

Senator Whish-Wilson said the Greens vote was lower than he expected it to be and there was "no doubt we've been tarred with the Labor brush".

He said the Palmer United Party result, which won 7 per cent of the vote, was unexpected.

"We estimated they might get a couple of per cent and they're sitting on six at the moment, they have taken some protest vote, spent a lot of money, the anti-politician thing is probably registering with people, we see them as a a threat."
