The Liberal National Party will can Brisbane's Cross River Rail project and force the public service to find $1.6 billion in savings if it is elected to govern at the Queensland election on Saturday.
Shadow treasurer Scott Emerson released the party's costings on Thursday, proposing $5 billion in savings, which will help pay for its $4.3 billion worth of election commitments.
Included in that is a plan to "reprioritise" the $2.56 billion Labor had allocated to its pet CRR project over the next four years to other infrastructure programs.
Only about $200 million would be kept to help retain the CRR delivery authority.
Mr Emerson said the LNP had "always acknowledged" there would be a need for a second rail crossing over the Brisbane river, but it wasn't required until 2026.
"The LNP is not walking away from CRR ... we're taking our time to make sure it stacks up," he said.
Mr Emerson, who spoke two hours after Treasurer Curtis Pitt released Labor's costings, said the full cost of CRR was about $15 billion so it "wasn't even close" to being fully funded by Labor.
If elected, the LNP also plans to implement a whole-of-government efficiency program and save $1.6 billion over four years.
Mr Emerson said it would be up to individual government departments to decide how it made savings, but he reiterated there would be no forced redundancies and the existing voluntary redundancy measures would remain in place.
He said the savings measures equated to less than one cent in every dollar.
"We believe that's a sensible approach to take," he said.
Mr Emerson said the public service would continue to grow under an LNP government, but not at the rate currently under Labor.
It also proposed to cut Queensland's debt by $700 million by 2021.
Current estimates show it would reach $81 billion under Labor, while under the LNP it is expected to be just under $80.5 billion.
