A union survey shows the Newman government has lost popularity in the wake of its June 3 budget.

The Newman government has lost popularity since handing down the Queensland budget, a union survey shows.

The Liberal National Party’s primary support has dropped two percentage points, to 37 per cent, in the two months to June 5.

But Labor’s primary vote is also down two percentage points, to 33 per cent, with the Palmer United Party (PUP) gaining ground from both parties.

The ReachTEL poll of 1671 respondents showed primary support for fledging party PUP, which has two MPs in the 89-seat parliament, has climbed from eight per cent to 12.3 per cent in the same time period.

Katter’s Australian Party trails far behind on 2.8 per cent.

The June 5 poll, commissioned by the public service union Together, was conducted two days after Premier Campbell Newman’s government handed down its third budget, the last before the 2015 election.

While there were no tax hikes or service cuts, the budget detailed assets worth $33.6 billion that would be sold if the LNP held power.

Most poll respondents, 59 per cent, believe they will be worse off financially because of the budget, with 32 per cent undecided and 10 per cent believing they’ll be better off.

Together has also released three other surveys, having polled a total of 6600 people in April and May, that suggest the LNP will lose a swag of regional seats.

They include Cairns and Barron River in far north Queensland and Pine River, Morayfield and Kallangur north of Brisbane.

Union secretary Alex Scott said PUP would be crucial to the next election result.

“(Party leader) Clive Palmer is likely to determine the outcome of the next election with his preferences,” Mr Scott told AAP.
