What is the government doing to protect your identity?

The government is looking at all possible solutions to protect and reissue victims’ identity documents.

The government has amended the Telecommunications Regulations 2021 to better protect Australians following the Optus data breach. They will allow Optus to share limited information with financial institutions and government agencies to detect and mitigate the risks of malicious activity, including ID theft and scams. These changes will reduce the impact of this data breach on Optus customers and enable financial institutions and government agencies to implement enhanced safeguards and monitoring.

The Department of Home Affairs has established a Commonwealth Credential Protection Register to help stop compromised identities from being used fraudulently. The register will prevent compromised identity credentials from being verified through the Document Verification Service. The Document Verification Service is used by government agencies and businesses, such as banks, to verify an individual’s identity online.

This will prevent credentials that are included on the register from being used fraudulently. However, this means rightful owners will not be able to use them online. New credentials issued following the data breach will work as normal. 

In the interim, impacted individuals should consider using alternative credentials or speak to service providers that ask for identification for other options, such as visiting the service in person to present the credential.

As Optus provides data, the issuing agencies will assess it and determine whether to add credentials to the register. As at 14 October 2022, the register includes around 100,000 Australian Passports. These passports can still be used for international travel.

The Australian Federal Police (AFP) has launched Operation HURRICANE to investigate the criminal aspects of the breach. The AFP has also launched Operation GUARDIAN, under the APF‑led JPC3, a joint partnership with law enforcement, the private sector and industry to combat cybercrime. Operation GUARDIAN is focused on shielding affected customers, where they can be identified, and working with industry to enhance protections for members of the public. The AFP is also monitoring online forums, including the internet and dark web, for criminals trying to exploit the breached data. The AFP will not hesitate to take action against those who are breaking the law.

The Australian Cyber Security Centre is supporting Optus with a cyber security incident response and assisting other Australian telecommunications providers to enhance their cyber security.

The Department of Home Affairs is working with Commonwealth, state and territory agencies to minimise the potential for exposed documents to be used fraudulently.

If your Medicare card details have been exposed, Services Australia will allow you to replace your Medicare card for free. If you believe there has been unauthorised activity to any of your Services Australia accounts, contact their Scams and Identity Theft Help Desk.

Passports are still safe to use for international travel. However, the government understands impacted Optus customers may be concerned about identity theft relating to their passports. Optus has agreed to reimburse the costs associated with replacing a passport due to the breach. Customers will need to pay for their replacement passport upfront and then seek a reimbursement from Optus. For more information go to Cyberattack Support ( or contact Optus customer service directly on 133 937.

The government will continue to update this factsheet as Optus provides more advice.
