Labor 'against everyone else': Palaszczuk

Labor have set themselves against their political rivals and lashed Clive Palmer's "big fat lie" five days out from the Queensland election.

Premier Annastacia Palaszczuk marked out the battlelines between her party and the rest of the field on Monday.

She even warned against voting for Katter's Australian Party (KAP), whose support Labor may need in a hung parliament.

"What we know very clearly is that (LNP leader) Deb Frecklington and the LNP are aligned with One Nation, they're aligned with Palmer, they're aligned with the Katters and everyone else," Ms Palaszczuk told reporters just five days out from the state election.

"It's basically us against everyone else."

Treasurer Cameron Dick unleashed on businessman Clive Palmer for sending thousands of voters a text message claiming Labor will introduce a death tax.

Labor have consistently denied his claim and his persistence is infuriating them.

"Clive you and I know this - your claim about a death tax in Queensland is a big fat lie," Mr Dick said.

"You know it, and I know it, and the people of Queensland know it."

However, there's uncertainty about Labor's plans after the treasurer unveiled their full costings to put pressure on the LNP to do so.

About $1 billion in savings will need to found in the health budget for Labor to fulfil its election pledge to put on thousands of new doctors and nurses.

"How you can find $270 million or thereabouts (in savings per year) ... is something that's easily done," he said.

"We delivered it when I was the health minister without impacting on the front line at all."

Mr Dick insisted that no staff would be cut to "satisfy efficiency dividends".

The premier promised $50 million over five years to cut water charges for about 6400 farmers from next year.

She says water charges will be slashed by 15 per cent for crops like sugarcane and 50 per cent for fruit and vegetables.

Ms Palaszczuk made the pledge at a mango farm in Burdekin, the LNP's most marginal seat, in north Queensland.

"We understand that our farmers are doing it tough," she said.

"And I want to support the agricultural industry to ensure that they can get the necessary support so they can continue the work that they do."

Ms Frecklington was in Townsville, where she promised $8 million for a new police taskforce to tackle the scourge of ice.

She says the money will resource the new methamphetamine taskforce, with the staff to come from existing police units.

Another $2 million will go towards mental health and drug awareness in partnership with the North Queensland Cowboys.

"We will shut down the big crime gangs that are pedalling drugs to our kids," Ms Frecklington told reporters.

"Under the LNP there will be more treatment, more prevention and more rehabilitation."

Meanwhile, the KAP are angling for a referendum on north Queensland statehood.

A party-commissioned ReachTEL poll on Monday showed 57 per cent of Townsville residents said they wanted a new state in north Queensland.

KAP leader Robbie Katter said there had been a push for statehood at federation and he would introduce legislation to hold a vote on the matter if he's re-elected.

"The Queensland government is controlled by Brisbane and therefore has always refused us this chance," Mr Katter said.

"They have everything to lose by separating, but we in the North have everything to gain."

Queensland polling day is on Saturday.
