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.
