Has your decision been reviewed by a:

  • Centrelink Authorised Review Officer (ARO) or
  • Centrelink Subject Matter Expert (SME)?; or
  • Child Support Objections Officer?

Your decision must first be reviewed by a Centrelink ARO (or in most circumstances a Centrelink SME), or a Child Support Objections Officer. Please contact Centrelink or the Child Support Agency to request this review. More information about how to do this can be found on Centrelink's website or the Child Support’s website.


You can make an application online for a first review of a Centrelink decision or a decision about child support made by the Department of Human Services by using the link on this page.

If you have already received a first review decision from the AAT and would like to apply for a second review of that decision, you will need to use a different online form.  If you are not sure which form you should use, the How do I find the right online form? page will help us direct you to the form you need to use.

In some cases there are time limits for making an application for review by the AAT – see the Time limits page of this website. Those limits apply regardless of how you make your application.

Frequently Asked Questions

Do I have to register to apply online?

No, you do not have to register to apply online.

Is there a fee to make an application for review online?

There is no fee to make an application for review in the SSCS Division of the AAT, either online or by any other means.

I want to apply for a review of more than one decision. Can I do it in one application?

An application for review of a Centrelink decision can include up to five decisions, if they were made on the same day by the Centrelink Authorised Review Officer or Centrelink Subject Matter Expert.

A separate application for review must be made for each child support decision that you would like the AAT to review.

I am not the applicant – does that matter?

You do not have to be the applicant (that is, the person who received the decision which you are asking the AAT to review) to send an application online. However, if you are sending an application on behalf of someone else, the application must be accompanied by at least one document as evidence of your authority to submit the online application.

If your application is for a review of a decision made by Child Support, some important examples of evidence of authority to submit an application are:

  • A lawyer submitting an application on behalf of someone must provide instructions to act on law firm letterhead or an Authority for representative form.
  • The holder of a Power of Attorney must provide a copy of the Power of Attorney.
  • A legal guardian must provide a copy of the Order appointing a guardian.
  • The Executor or Administrator of an Estate must provide a copy of the Will and/or Probate or Letters of Administration.

If your application is for a review of a decision about child support, you must read the Child Support Review Directions.

If you are not the applicant and it is your intention to act on behalf of the applicant during the course of the review, please visit the Representation page of this website for further information.
