Information Commissioner releases the Notifiable Data Breach report covering the second half of 2022. A 26% increase..no small thanks to Optus and Medibank. It is still an under report of the real rate of data breaches
March 1, 2023
Today the Information Commissioner released the latest Notifiable Data Breach report.
It makes for grim reading. The key findings are:
- 497 breaches were notified compared with 393 in January to June 2022 – a 26% increase.
- There was a 41% increase in data breaches resulting from malicious or criminal attacks. Malicious or criminal attacks accounted for 350 notifications – 70% of all notifications.
- Human error was the cause of 123 notifications (25% of all notifications), down 5% in number from 129.
- Health reported the most breaches (71), followed by finance (68). That the health sector provides the greatest number of breaches is no surprise.
- Contact information remains the most common type of personal information involved in breaches.
- The majority (88%) of breaches affected 5,000 individuals or fewer.
- 71% of entities notified the OAIC within 30 days of becoming aware of an incident. This is quite an indictment on compliance. Almost 30% of entities did not notify the OAIC within the statutory maximum of 30 days. That bespeaks poor culture.

Several large-scale data breaches impacted millions of Australians’ personal information in the second half of 2022, as part of a 26% increase in breaches overall, according to the latest Notifiable data breaches report released today.
Australian Information Commissioner and Privacy Commissioner Angelene Falk said cyber security incidents in particular can have significant impacts on individuals, and organisations need to be alert to the risks.
“We saw a significant increase in data breaches that impacted a larger number of Australians in the second half of 2022,” she said.
“Cyber security incidents continue to have a significant impact on the community and were the cause of the majority of large-scale breaches.”
Thirty-three of the 40 breaches that affected over 5,000 Australians were the result of cyber security incidents.
“Organisations should take appropriate and proactive steps to protect against and respond to a range of cyber threats,” Commissioner Falk said.
“This starts with collecting the minimum amount of personal information required and deleting it when it is no longer needed.”
Commissioner Falk said organisations need to be vigilant as large-scale compromises of personal information may lead to further attacks.
“As personal information becomes increasingly available to malicious actors through breaches, the likelihood of other attacks, such as targeted social engineering, impersonation fraud and scams, can increase.
“Organisations need to be on the front foot and have robust controls, such as fraud detection processes, in place to minimise the risk of further harm to individuals,” she said.
The Office of the Australian Information Commissioner has clear expectations of best practice with regard to data breach preparation and response, to ensure individuals are protected from harm.
“In response to a breach, organisations need to provide information to individuals that is timely and accurate.
“As well as setting out the kinds of information breached, the notification must include recommendations about clear steps people should take in response,” said Commissioner Falk.
The reporting period also saw the enactment of the Privacy Legislation Amendment (Enforcement and Other Measures) Act 2022. Among other things, the Act:
-
- provides the Commissioner with new and greater powers to share information with other authorities about data breaches
- provides the Commissioner with a new power to obtain information and documents relevant to an actual or suspected eligible data breach
- enables the Commissioner to conduct an assessment of the ability of an entity to comply with the Notifiable Data Breaches scheme, including the extent to which the entity has processes and procedures in place to assess suspected eligible data breaches, and provide notice to the Commissioner and individuals at risk from such breaches
- significantly increases penalties for serious or repeated privacy breaches, which includes non-compliance with the Notifiable Data Breaches scheme.
“While we will continue to work with organisations to facilitate voluntary compliance, we will use these regulatory powers where required to ensure compliance with the Notifiable Data Breaches scheme,” said Commissioner Falk.
“We also welcome the further proposals to strengthen the Notifiable Data Breaches scheme in the Attorney-General’s Department’s Privacy Act review report.”
