A public sex offenders register could become law in Victoria if the Coalition wins next year's state election.

Opposition Leader Matthew Guy said he was seriously considering the idea as part of the Coalition's policy platform for the November 2018 poll.

Mr Guy recently met Bruce and Denise Morcombe, whose 13-year-old son Daniel was abducted and murdered on Queensland's Sunshine Coast in 2003.

Serial paedophile Brett Peter Cowan was convicted of the murder in 2014 and sentenced to life in jail with a minimum non-parole period of 20 years.

The Morcombes have since been advocating for Daniel's Law, which would list violent sex offenders on a publicly accessible website, including their name, any aliases, and a current photograph.

The Morcombes also proposed naming the "general geographical area" the offender lived in, but not a specific street address.

Victorians looking for 'greater sense of security'

The website would also include a broad outline of the offender's criminal history without any details that could identify victims.

"I think we need to now have a look at this as a concept in Victoria," Mr Guy said.

"I think Victorians are looking for something that is different, that is stronger, that gives a greater sense of security and safety.

"So it is something that I am actively looking at."

Victoria has kept a Register of Sex Offenders since 2004 but only people authorised by the police could access it.

Mr Guy said he was not concerned that making the register public could encourage vigilantism.

"It hasn't occurred overseas and if you've got appropriate safeguards and deterrents in place ... it hasn't had issues in the United States, then I doubt we'll have issues in Australia," he said.

Asked to respond to the idea, Police Minister Lisa Neville said the Government listened to the advice of Victoria Police, not the Opposition.

Victorian Senator Derryn Hinch has also been lobbying for a national public register of convicted sex offenders, similar to Megan's Law in California.

Western Australia has a restricted public register which displays photographs of high-risk offenders, but only in the suburb and adjoining suburbs of the person accessing the register.

Applicants must also provide their own personal details before accessing the register.
