Parents have been promised more power to obtain details, including photographs, of sexual offenders under a new state opposition plan.

The policy will not allow for a search of the public register of sex offenders, but will enable worried parents to apply for details from a newly created commissioner of the sex offenders register.

Photographs and other details of sex offenders could be obtained by either applying for a local search for offenders in the neighbourhood, an individual search of any suspected person and missing offenders who breach reporting conditons.

Opposition Leader Matthew Guy told 3AW's Neil Mitchell that Victorians deserved to know if they had a high-risk serial sex offender living in their street.
