Protection services

The Australian Criminal Intelligence Commission is committed to protecting children and young people from the risk of harm or abuse. Several elements of our work directly support providing a safe environment for children in Australia.

Police use our child protection systems to help identify and manage offenders against children, helping to protect children at risk. This includes the Working with Children Checks, National Reference System (WWCC NRS) and the National Child Offender System (NCOS).

The Working with Children Checks, National Reference System (WWCC NRS) allows screening agencies in each state and territory to share key negative decisions for applicants who have applied for a Working with Children registration. The WWCC NRS only stores negative decisions.

The National Child Offender System (NCOS) helps police protect the community by enabling them to uphold child protection legislation in their state and territory. It 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. It also enables alerts to be generated when registered persons notify that they are planning to travel interstate or overseas.

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 web-based application is designed to assist police register, case manage and share mandatory information about registered persons as required by legislation.

Requests about information contained on this system should be directed to the child protection unit in the relevant state or territory as listed below:
