With the State Government set to receive final report of the Costello audit later this week, Mr Newman has again promised that no major asset will be sold before the next election.
But he says contracting out services such as housing or respite care would not be privatisation.
"Frankly, government wastes money in Queensland," he said.
"That's what we've inherited from Anna Bligh and Labor, we're determined to fix it.
"These unions should sit down and work with me and my Government.
"I respectfully request that they do that because that's what I'm after."
"The Government is trying to find a way of saying privatisation isn't privatisation, whether they call it contracting out, whether they call it outsourcing," he said.
Speaking in Hervey Bay ahead of tonight's community Cabinet meeting, Mr Newman has insisted he is talking about something other than privatisation, and that it is "about getting the best bang for the taxpayers' buck".
"I have no philosophical point of view in terms of whether people are employed in house or contracted from external companies," Mr Newman said.
"I don't want mums and dads and families to pay one dollar more than they ought to in tax."
