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.

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.

The ANCOR was enhanced late 2017 to support changes made to the Passports Legislation Amendment (Overseas Travel by Child Sex Offenders) Act 2017. The Child Protection Offender Registries in each state and territory can request the Department of Foreign Affairs and Trade (DFAT) to:

  • cancel an Australian passport
  • request the surrender of a foreign passport
  • issue a limited validity Australian passport.

An Australian Child Protection Offender Reporting scheme is 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 allowing police to exercise authority to case manage offenders thereby reducing the likelihood that an offender will reoffend. The register and its supporting legislation also assists police in the investigation and prosecution of any future offences offenders may commit.
