Record Data Breach Notifications Highlight Cybersecurity Challenges in Australia

• •In 2025, Australia saw a record 1,205 data breach notifications under the NDB scheme.
• •Malicious cyber activity, especially hacking, was the leading cause of reported breaches.
• •82% of Australians now consider data breaches the top privacy risk, reflecting growing public concern.

In 2025, the Office of the Australian Information Commissioner (OAIC) received 1,205 data breach notifications, the highest since the Notifiable Data Breaches (NDB) scheme began in 2018. This surge reflects increasing cyber threats and heightened awareness of notification obligations among organizations. Malicious activity, particularly cyber hacking, was the primary cause of these breaches, with health service providers being the most affected sector. The 2026 Australian Community Attitudes to Privacy Survey revealed that 82% of Australians now view data breaches as a top privacy risk. The OAIC emphasized the need for strong data governance and incident response frameworks to mitigate risks. AI's role in both facilitating and combating cyber threats is becoming increasingly significant. Organizations are urged to continuously enhance their security measures to protect against evolving risks.
