The Office of the Australian Information Commissioner (OAIC) defines a Privacy Impact Assessment (PIA) as a systematic assessment of a project that identifies privacy impacts and sets out recommendations for managing, minimising or eliminating that impact. PIAs are an important component in the protection of privacy and should be part of agencies’ risk management and planning processes. Since 1 July 2018, it has been mandatory for Australian Government agencies to maintain a register of the PIAs they conduct, and to publish that register on their website.
