Those deemed by a court as unsuitable for release into the community at the end of a prison sentence will be sent to a 10-bed facility to be built within the existing prison system.
Others will be subject to electronic monitoring, curfews, no-go zones and strict reporting requirements, it was announced on Thursday.
The Sex Offender Response Unit, made up of police, intelligence analysts and corrections staff, will manage the expanded scheme and a new authority will be created to oversee unit.
It will all be a part of $308 million package to implement the recommendations of the Harper Review.
