National Child Offender System

The National Child Offender System (NCOS) is a web-based application that allows Australian police to record and share child offender information. It directly enables police in each state and territory to manage key information to meet their requirements under respective child protection legislation. NCOS has now been enhanced to support changes made to the Passports Legislation Amendment (Overseas Travel by Child Sex Offenders) Act 2017. Registrars of Child Protection Units in each state and territory are able to request through NCOS, the cancellation, surrender or issuing of a temporary Australian Passport for offenders that are Australian citizens.

An Australian Child Protection Offender Reporting scheme was established by legislation in each Australian state and territory. This national scheme requires child sex offenders, and other defined categories of serious offenders against children, to keep police informed of their whereabouts and other personal details for a period of time after they are released into the community. This register is not intended to be punitive in nature, but is implemented to protect the community by reducing the likelihood that an offender will reoffend, and to facilitate the investigation and prosecution of any future offences that they may commit.

The NCOS consists of the Australian National Child Offender Register (ANCOR) and the Managed Person System (MPS):

  • The ANCOR allows authorised police officers to register, case manage and share information about registered persons. It assists police to uphold child protection legislation in their state or territory.
  • The MPS holds information on alleged offenders who are charged but not convicted, or after an offender’s reporting obligations have been completed.

Any requests about information contained on the NCOS should be directed to the Child Protection Unit in the relevant police agency. The contact details for the Child Protection Unit in each state and territory are listed below:
