About this document

Part 6A of the Privacy and Personal Information Protection Act 1998 (PPIP Act) established the Mandatory Notification of Data Breaches Scheme (MNDB Scheme), which requires public sector agencies to notify the Privacy Commissioner and affected individuals in the event of an eligible data breach involving personal or health information that is likely to result in serious harm. The MNDB Scheme commenced on 28 November 2023.

The Information and Privacy Commission (IPC) publishes quarterly statistical information on the number of eligible data breach notifications received under the MNDB Scheme. This snapshot is intended to provide agencies and the public with key summary data for the six-month period between July and December 2024. 

The Privacy Commissioner will also publish the January – June 2025 Data Snapshot and an annual Trends Report for the full 2024–25 financial year.
