Data breach lessons

Optus data breach

The ATO is aware of last year’s Optus data breach and that people who have been affected might be concerned about their personal data, and is assuring people that ATO systems have not been affected by the Optus data breach.

The ATO recommends that anyone who thinks they have been affected by the Optus data breach should contact Optus Customer Service on 13 39 37.

Information for those caught up in the data breach is available from the Australian Cyber and Security Centre at

The ATO also reminds the community that it is important to always be vigilant for suspicious activity.  The following tips can help protect accounts and keep personal information safe:

  • Use multi-factor authentication for accounts where possible.
  • Be careful when clicking on links and providing personal information.
  • Make sure contact details are up to date when using online services.
