The Australian Government has released an exposure draft of the Privacy Amendment (Personal Data Protection) Bill 2026 (the Exposure Draft) which, if enacted in its current form, will put in place a range of very significant reforms to the Australian Privacy Act 1988 (Cth) (Privacy Act) that are likely to have a considerable impact on personal information handling practices. Submissions can be made in relation to the Exposure Draft until 18 September 2026.

The Exposure Draft includes some of the long-anticipated "second tranche" of privacy reforms, following the first tranche enacted by the Privacy and Other Legislation Amendment Act 2024 (Cth) (Amendment Act). It also includes some new changes, including overhauling certain Australian Privacy Principles (APPs) in a manner aligned with the Productivity Commission’s recommendations in its 2025 report on Harnessing data and digital technology

Key obligations proposed in the Exposure Draft include a requirement that all collection, use and disclosure be “fair and reasonable”, additional restrictions on direct marketing, a requirement to take into account the best interests of children when applying the “fair and reasonable” standard in relation to personal information about children, and a 72-hour timeframe for notification of eligible data breaches.

The introduction of controller and processor provisions is likely to be good news for many suppliers, particularly technology providers, who process personal information as part of the products and services they provide to other entities.

It is important for entities to start assessing the proposed changes and their impacts to ensure that they can address any major issues in submissions and can comply with the amended laws when they take effect. The proposed commencement date for the legislation has not yet been published, which means that the amount of time available for entities to prepare for the changes is not yet known.

The reforms aim to bolster privacy protections for Australians and address emerging risks from new technologies, including artificial intelligence and wearable devices such as smart glasses. A Privacy Reform Consultation Paper (the Consultation Paper) released with the Exposure Draft seeks views as to whether the reforms proposed adequately address those risks. 

This article provides an overview of the Exposure Draft's key proposals, sets them in the context of the broader reform process, and identifies some of the most significant practical implications for organisations subject to the Privacy Act.
