The easiest way to apply is online. You can set up self service at the same time. Then you’ll be ready to manage your payments online when they start.
Before you start
If you or the other parent live outside Australia, you may need to apply to that country’s child support authority instead.
If asking for child support puts you at risk
Call our families line and ask to speak to a social worker if you don’t want to seek child support because you’re worried about risks to you or your family.
If you’re at risk of, or dealing with, family or domestic violence:
- call 1800RESPECT on 1800 737 732 or
- go to the 1800RESPECT website and click on Connect to a counsellor
You can talk privately on the phone or online to someone who’s trained to help. It’s free and open 24/7.
Set up self service
- Go to the self service page
- set up a myGov account if you don’t already have one, and
- sign in to myGov and start a Child Support online account
Fill in the online Application for child support assessment.
What may be different
If you’re a non-parent carer, use the Application for child support assessment - Non-parent carer instead.
If you live outside of Australia, use the International application for an Australian child support assessment form instead.
Submit your form
You need to give us:
- your form, and
- any other documents we’ve asked for as you go through the form
You can submit most documents online through your Child Support online account.
If you can’t apply online
You can call us instead.
If you change your mind
If we haven’t accepted or refused your application yet, you can withdraw it.
Wait for the result
We’ll write to you and the other parent to tell you our decision.
If we make an assessment, we’ll send your child support assessment notice. This says:
- how much you’ll receive or pay, and
- when your payments will start
Check your details
Check that all your details on the assessment notice are right.
You need to tell if they aren’t or if they change later.
If you think our decision was wrong
Both parents have the right to object to most of our decisions.
