The election of Derryn Hinch to the Senate could lead to a fresh push for a national public register of sex offenders, Queensland child safety ambassador Bruce Morcombe says.

Bruce and Denise Morcombe are continuing to advocate for the introduction of a public register under what has been dubbed Daniel's Law.

Their son Daniel was abducted and murdered in 2003 by child sex offender Brett Peter Cowan.

Mr Morcombe said Melbourne senator-elect Derryn Hinch has promised to lobby for the national register when he takes his seat in Federal Parliament.

"It'll potentially allow a parent who can sit down with their children, as they should be doing now and say these are the reasons we need you to be safe," Mr Morcombe said.

"If you can sit down in front of a computer and say look, in this suburb there are X number of sexual offenders on this register, it might just bring home the truth."

Mr Morcombe said he had discussed Daniel's Law with Mr Hinch on several occasions.

"The conversations are always encouraging and we're definitely on the same page to make sure that our kids are safe," he said.

"Derryn Hinch is soon to be senator, definitely one of his big ticket items for election was to protect kids, justice for victims of crime and of course a public sex offenders register.

"We are really keen with many of those items and indeed I have congratulated Derryn."

'Bruce and I will get to Canberra and get it done', Hinch says

Mr Hinch said he would continue to push for Daniel's Law until it was passed at a state and federal level.

"It will take a little longer, getting the state attorneys-general and the federal attorney-general together," he said.

"It will be like herding cats.

"Bruce and Denise came and walked with me on the Jail 2 Justice walk.

He said 160,000 people had signed a petition calling for Daniel's Law.

"So the community wants it," he said.

"Get me in there and I'm sure Bruce and I will get down to Canberra and get it done."

The Northern Territory Parliament was the first to consider a state-based public sex offenders register, based on Daniel's Law.

It was due for debate in the Legislative Assembly in November but was withdrawn following criticism from the community and the Northern Territory Criminal Lawyers Association and the Northern Territory Law Society.

The Northern Territory Government has since held public consultation, but Mr Morcombe said the bill remains in a holding pattern.

"There were some disagreements as to the wording and text and implications of the bill and it was being reviewed and redrafted for some of those prickly areas," he said.

"We still want it to have some grunt."

Mr Morcombe said he understood the introduction of a sex offenders register could lull a community into a false sense of security.

"The only people that are on the public sex offenders register are people that have been convicted," he said.

"There could be several people that just haven't been caught yet.

"But if we don't use the tools that are potentially available, we're just letting our kids down."
