Queensland's new LNP government has accused the former Labor administration of lying to the community about the cost and viability of a huge pumped hydro scheme, branding it a "con job" and "hoax".

Premier David Crisafulli has followed through on his election commitment to scrap Labor's Pioneer-Burdekin Pumped Hydro Project, slated for an area west of Mackay, in north Queensland.

Pumped hydro facilities generate power when huge quantities of water are released from one reservoir into a second, lower, storage facility.

Deputy premier Jarrod Bleijie said briefings and a "detailed analytical report" given to the incoming government revealed the true forecast cost of the scheme is $36 billion, far more than the initial $12 billion price tag.

"Labor's Pioneer-Burdekin Pumped Hydro hoax was a hoax, and it was a con job on the people of Queensland by the Labor Party."

Mr Bleijie said he was able to get costings for the project "48 hours into a new government".

"Labor knew about it, and they didn't tell Queenslanders about it," he said.

The report from government entity Queensland Hydro modelled three options for different sized pumped hydro systems in the Pioneer-Burdekin Valley.

A Queensland Hydro spokesperson confirmed to the ABC the report "was submitted to the government on the day it was finalised".

"Final analysis of the options, and conclusion of all studies, was completed during the caretaker period, so it was not provided at that time to either the then-government or opposition," the statement said.

The first, the former Labor government's chosen path and the biggest, was deemed not "commercially viable", as it was estimated to cost between $33 billion and almost $37 billion.

Labor's earliest estimates of the project's cost was around $12 billion, but it later indicated the figure was likely to be higher.

The report also found an absence of evidence that a system of 5,000 megawatts (MW) was needed in Queensland.

Further, there was just a 50 per cent chance the first stage would be online by 2035, and the second stage by 2038, making it three years behind schedule.

The former government had committed to shut off its coal fired power stations by 2035.

However, the report modelled two other options for smaller pumped hydro projects at Pioneer-Burdekin, with an estimated cost between $22 billion and $28.2 billion.

It recommended each of these options be considered, delivering sound financial return to the state.

But the government on Monday said it wouldn't be proceeding with any of the options, instead planning smaller hydro facilities in locations yet to be chosen, with a timeline currently unknown.

Mr Miles said he had not seen the Queensland Hydro report while in government.

"We asked for a detailed analytic report, it was, as I understand it, completed on the 31st of October," Mr Miles said.

He said the report "identifies an option" within the cost range "that has been in the public domain for some time and describes it as exceptional value."

The ousted premier said it would now be up to the LNP to find an alternative.

"They are the incoming government, that have the right to cancel that project, but they now need to outline how they will replace all of that storage."

Premier David Crisafulli on Sunday visited north Queensland to meet with Eungella locals. 

More than 50 landowners who had their properties purchased to make way for the scheme will now be invited to buy their land back.

When asked on Monday if scrapping the Pioneer-Burdekin scheme meant Queensland would not meet its emission reduction targets, Mr Bleijie said the treasurer would be "working out a road map".

"That's why we put treasury and energy together … the energy minister will work out a road map with Queensland Hydro and all the government-owned corporations and treasury and the department of energy to work out what that looks like," Mr Bleijie said.

A spokesperson for the Labor opposition said "the only con here" is Mr Crisafulli not revealing how he would replace the energy produced by the Pioneer-Burdekin scheme.

They rejected claims the Labor government had the costings before the election.

"In the previous term of government Queensland Treasury never received the detailed analytical report for the Pioneer Burdekin Pumped Hydro Project, as a result Queensland Treasury did not provide a finalised cost of the project," the opposition spokesperson said.

Labor will hold a caucus meeting on Tuesday to vote on who will fill the roles of opposition leader and deputy leader.

Steven Miles and Cameron Dick are currently running unopposed for each position.

"I think you saw during the campaign just how I intend to hold David Crisafulli to account and that's the kind of opposition leader I will be," Mr Miles said.

Mr Miles said he is supporting Cameron Dick to be his deputy and the pair are "eager to continue as a team".

He said former health minister Shannon Fentiman "will play a very senior role in my opposition".

It's the first meeting of MPs since the party was booted out of government.

More than a week after the October 26 election, the seats of Aspley, Mulgrave and South Brisbane are still considered in doubt.
