Rockhampton MP Bill Byrne said at this stage a public register was only theoretical, and he would reserve his judgment until he had the opportunity to review all information.
"I have seen commentary that's been put out by the LNP cabinet ministers and they seem to be equally divided, as I imagine the rest of the community would be, about such a matter," he said.
"There are reasonable concerns that the notion of vigilantism would rear its head; there have been examples of that in Queensland."
- Oh it will! All you have to do is look at these examples.
"While I'm not defending the histories of those that are targeted, it does give me concern that the prospect of vigilantism exists."
He also raised concerns about people who were not a danger to the community being placed on a public registry.
One example of this could be underage teenagers having consensual sex, which is technically illegal.
"We don't want to have two 15-year-olds that have had what I consider to be a consensual relationship to end up on the sex offender register," he said.
"It could be a catch-all legislation that has ramifications well beyond the intention of the legislation."
"The bikie legislation was meant to target the criminal element of motorcycle gangs, and it has had a much broader effect than what was the intention of the legislation."
He maintained that the idea behind the justice system was to hold people accountable for their actions, but to also offer them a chance of rehabilitation.
