Broadcaster Derryn Hinch is meeting Queensland Attorney-General Jarrod Bleijie in a bid to sell the idea of an American-style sex offender register.

Broadcaster Derryn Hinch is hoping to convince Queensland to become the first state to adopt his push for a US-style public sex offender register.

Hinch is meeting with Attorney-General Jarrod Bleijie on Tuesday morning to discuss his proposal to name and shame sex offenders.

But the media personality says his meeting with Queensland’s top law officer, two months after a meeting with Victoria’s attorney-general Robert Clark, does not mean Queensland will agree.

“He may be totally opposed,” he told AAP.

“I wouldn’t put words in his mouth.”

Bruce and Denise Morcombe, whose 13-year-old son Daniel was murdered in 2003 by serial pedophile and child rapist Brett Cowan, support a sex offender register.

Hinch, who has served jail time for publicly naming sex offenders, said he didn’t believe sex offenders could be rehabilitated and secrecy was their biggest weapon when they were released from jail.

“They’re underground now,” he said.

“Murderers don’t get their names suppressed when they get out of jail.”

But he disapproves of vigilantes taking action against pedophiles.

“I’d delete people from my Facebook page who say `Rolf Harris should be drawn and quartered and let the prisoners take care of him’,” he said.

“Vigilantes should be treated with absolute distain and should have the full extent of the law hit them.”

Mr Bleijie said Queensland’s dangerous sexual offender laws were under review and he was happy to meet anyone who had ideas that could improve community safety.

But one child protection advocate doesn’t support a register.

Founder of Bravehearts child protection group Hetty Johnston says the continued detention of dangerous sex offenders, not a register, is the answer.
