PREMIER Campbell Newman is tipped to announce before Christmas a commission of inquiry into the bungled state health payroll system.
Mr Newman told ABC Radio on Tuesday morning that an announcement would be made before Christmas.
The LNP leader said he wanted to get to the bottom of the IBM issue.
Computer giant IBM was contracted to set up the plagued payroll system.
"It's something under serious consideration, there is no secret of that, it has been canvassed in Parliament," he said.
"But I am not in a position to say anything today.
"But I believe Queenslanders deserve to hear what has gone on.
"This is a $1.2 billion debacle - arguably the largest single public sector project funding debacle of all time in this nation.
"I don't think it's appropriate for it to be written off and we say 'too bad too sad' and move on.
"I don't think that's going to happen."
Mr Newman said his government had heard stories of "insiders" who would be prepared to talk to a commission of inquiry but were concerned about indemnity.
The Queensland Opposition released hundreds of documents in October detailing legal advice given to the former Bligh government over the payroll bungle.
