Fair Work Commission AI Rules Start 20 October 2026

Posted: 5 September 2026 · Category: Legal, Compliance & HR

TL;DR: From 20 October 2026, using ChatGPT, Claude, Copilot or Gemini on a Fair Work Commission case carries three duties. Tell the Commission. Verify every fact yourself. Say in the document that you did. Ignore it and you can be ordered to pay the other side's costs.

What changed

The Fair Work Commission has published a Guidance note on generative AI, and its requirements apply to all Commission matters from 20 October 2026. The Commission names the tools itself: "ChatGPT, Claude, CoPilot and Gemini are examples of GenAI."

If you use one to create, write, edit or otherwise prepare a document, three things become mandatory. Tell the Commission you used GenAI and explain how. Check the document yourself so every piece of information is accurate, relevant and supported by real evidence and legal authorities. Then state in the document that you have completed those checks.

Witness statements carry more. The witness must confirm the document is based on their own knowledge, in their own words, and true to the best of their knowledge. Lawyers and paid agents must also hyperlink any case law. Some forms will carry a GenAI question from 20 October. For documents without one, the Commission supplies wording to paste at the top.

Why it matters for Australians

This is the first Australian rule that reaches into how an ordinary person uses a chatbot, rather than how a company builds one.

Unfair dismissal and general protections matters are largely run by people without lawyers. The Commission is blunt about why it moved. GenAI content "may contain incorrect facts, fake legal cases, misleading information or outdated law." The consequences are not theoretical: documents given less weight or disregarded, a costs order against you, or your case dismissed.

Two practical things. The Commission has published set-up prompts to paste into a chatbot before you ask it about your matter. They tell the tool to work from the Fair Work Act 2009 and real Australian decisions. Don't invent authorities. Don't assume the case is strong. Say so plainly when the law doesn't support the user. It is the most useful free thing on the page — and a regulator openly conceding that these tools flatter people. Second: keep personal details and confidential case information out of public GenAI tools. The Commission warns that what you type may not stay private.

Does this change our recommendation?

Not our scores. It changes the advice attached to four of them.

ChatGPT, Claude, Microsoft Copilot and Gemini remain capable general assistants and we still rate them that way. None is a substitute for legal advice — and from 20 October an Australian tribunal says so in its own words. Use them to organise your thinking and draft plainly. Then verify every fact, authority and date yourself before it goes near a form, and disclose that you used them.

We are adding an Australian-context note to those four reviews and to our HR and legal coverage ahead of the date.

This is general information, not legal advice. For your own matter, talk to a qualified practitioner — you may qualify for free help through the Commission's Workplace Advice Service.

Frequently asked questions

What changed?

The Fair Work Commission published a Guidance note on the use of generative AI in Commission cases. From 20 October 2026, anyone who uses GenAI to prepare an application, submission, witness statement or other document must disclose that use, verify the content themselves, and state in the document that they have done so.

Does this affect Australian users?

Directly, if you have a matter before the Commission — most often unfair dismissal or general protections. The Commission names ChatGPT, Claude, Copilot and Gemini as examples. Failing to follow the requirements can mean your documents are given less weight or disregarded, a costs order against you, or your case being dismissed.

Does it change our recommendation?

It doesn't change any score. It adds a condition: these four assistants are fine for organising your thinking, but every fact, case and date must be checked by you before it is filed, and the use must be disclosed. Do not enter personal or confidential case details into public GenAI tools.
