Centrelink-Child Support information exchange 277-04080000



This document outlines the process for child support staff to:

  • exchange information between Centrelink and Child Support
  • request information from Centrelink systems, and
  • process requests for information from Child Support systems

Information exchange

Information and data is exchanged automatically between systems in Child Support (Cuba) and Centrelink (Income Security Information System (ISIS)). This may occur on a daily, weekly or monthly basis, depending on the type of customer information provided. The data exchange also occurs when the External Information window in Cuba is refreshed using the CNTLK refresh button.

Data exchange processes automatically trigger a request for matching and exchange of data when customer or child details are updated, or case events occur. This request and exchange occurs daily.

To respond to customer needs, there are times when information is manually requested from and by either Child Support or Centrelink.

Information must only be disclosed if that action complies with the 2016 Governance Arrangement. See References for details of the Governance Arrangement.

Entitlement files

Entitlement files are sent weekly and contain child support case entitlement information including:

  • details of persons (name, date of birth, reference number) who have applied for a child support assessment in order for Centrelink to match data for identification of mutual customers
  • the outcome of their child support applications including:
    • entitlement amount
    • child details
    • collection method
    • ending of assessments

  • Customer information including current contact, benefit, relationship and child(ren) details of mutual customers
  • Centrelink Deduction action (new requests, updates and cessations)
  • Determining whether a customer is a mutual customer of both Child Support and Centrelink
