Read more about what you can do using self service.

If you don’t have access to a self service option, please call the families line. If you need an interpreter, let us know and we’ll arrange one for you.

If you want to speak to someone in your language, call our Multilingual Phone Service.

If you’re an Aboriginal or Torres Strait Islander Australian, you can also call and speak to our Indigenous call centre for help.

There are some changes you can’t tell us using a self service option. You need to call the families line to tell us about changes to the following things:

  • your relationship changes, for example if you become partnered or separated
  • your child’s care arrangements - the amount of time a child is in your care changes or your child leaves your care
  • your child dies
  • your child is in a prison or juvenile justice centre as a result of a court order
  • your child is leaving the country, temporarily or to live somewhere else alone.
  • changing or correcting your name.

Contact numbers available on this page.

Centrelink families line

Use this line if you need help with family payments, such as Family Tax Benefit, Child Care Subsidy, Parental Leave Pay, Foster Child Health Care Card, Health Care Card or Pensioner Concession Card.

Monday to Friday 8 am to 8 pm

If your child’s Youth Allowance payment has been suspended, it may be because we still need information about your income. We may have sent your child a letter asking for this in September or October, read how you can update your income details online.
