Notifiable Data Breaches Report – July to December 2020

January 28, 2021

About this report

The Office of the Australian Information Commissioner (OAIC) periodically publishes statistical information about notifications received under the Notifiable Data Breaches (NDB) scheme to assist entities and the public to understand the operation of the scheme. This report captures notifications made under the NDB scheme for the period from 1 July to 31 December 2020.

Where data breaches affect multiple entities, the OAIC may receive multiple notifications relating to the same breach. Notifications relating to the same incident are counted as a single notification in this report.

The source of any given breach is based on information provided by the reporting entity. Where more than one source has been identified or is possible, the dominant or most likely source has been selected. Source of breach categories are defined in the glossary at the end of this report.

As with previous reports, notifications made under the My Health Records Act 2012 are not included as they are subject to specific notification requirements set out in that Act.

NDB scheme statistics in this report are current as of 8 January 2021. However, a number of notifications included in these statistics are still under assessment and their status and categorisation are subject to change. This may affect statistics for the period July to December 2020 that are published in future reports. Similarly, there may have been adjustments to statistics in previous NDB reports because of changes to the status or categorisation of individual notifications after publication. As a result, references to statistics from before July 2020 in this report may differ from references in earlier published reports.

Executive summary

The NDB scheme was established in February 2018 to improve consumer protection and drive better security standards for protecting personal information. Under the scheme, any organisation or government agency covered by the Privacy Act 1988 must notify individuals affected and the OAIC when a data breach is likely to result in serious harm to an individual whose personal information is involved.

The OAIC publishes twice-yearly reports on notifications received under the NDB scheme to track the leading sources of data breaches, and to highlight emerging issues and areas for ongoing attention by regulated entities.
