Step 1: get started

Sign into myGov or the myGov app and select Child Support.

From the menu, select My profile then My profile summary.

From the My profile summary page, select Edit contact details.

We’ll give you a summary of the details you’ve told us about.

Check the Contact details to make sure they’re correct.

Select either:

  • Edit contact details if you need to make any changes

If all the details are correct, read the declaration. If you understand and agree with the declaration, select I have read, understood and accept the declaration, then select Submit.
