If your organisation uses software to help decide things about people, automated decision-making transparency is now a task with a date on it. From 10 December 2026, Australian privacy law requires you to tell people, in your privacy policy, about the automated decisions you make about them. This post gives you the inventory to run before the date, and how to turn it into a privacy policy section a person can actually read.
What automated decision-making transparency requires on 10 December 2026
The obligation comes from the Privacy and Other Legislation Amendment Act 2024, which amended Australian Privacy Principle 1. Put plainly: if you are an APP entity and you use personal information in an automated decision that could affect a person's rights or interests, your privacy policy has to say so. It has to describe the kinds of personal information you use, and the kinds of decisions you make that way.
From 10 December 2026, APP entities that use personal information in ADM with the potential to affect rights or interests will be required to provide information in their privacy policies about the kinds of personal information used and the kinds of decisions made using ADM.
Two things stand out. The disclosure sits in your privacy policy, a document you already publish. And the test is about the effect on a person, not the technology. If a decision could change what someone gets, pays, or is offered, it is in scope.
