myGov help - Link Child Support to myGov if you have a Child Support Reference Number

Instructions on how to link Child Support to your myGov account if you have a Child Support Reference Number (CSRN).

To start you’ll need a myGov account. If you don’t have one, you can go to the myGov website to create one.

If you’re not an existing Child Support customer, you won’t be able to link to your myGov account.

We’ll ask you some questions to make sure we match the correct Child Support record to your myGov account.

You’ll need to have all of the following:

  • your Child Support Reference Number (CSRN)
  • answers to some questions specific to you, such as your Child Support payment history and bank account details.

You will also need one of the following:

  • access to the mobile number or email address registered with Child Support to receive a one-time passcode
  • one identity document, such as your current Australian driver licence, Australian birth certificate or visa details

Make sure you have this information ready before you begin.
