Using AI in a Fair Work Case? New Rules Start 20 October
From 20 October, using ChatGPT to draft a Fair Work submission means disclosing it and verifying every citation is real. What Australian employers must do.
From 20 October, AI in your Fair Work case comes with rules
Sack someone, end up defending the claim, and there's a fair chance you'll reach for ChatGPT to help draft the response. From 20 October 2026, that's allowed — but it comes with two obligations you can't skip. You have to tell the Fair Work Commission you used AI, and you have to verify that every fact, case and quotation it produced is real. Miss the second one and you're not just non-compliant; you've handed the decision-maker a reason to doubt everything else you filed.
This is not hypothetical. Commission Members reported spotting signs of generative AI in 50 to 75 per cent of the cases they handled in the six months to March 2026. In one unfair dismissal matter, an applicant's AI-generated legal citations turned out not to exist at all.
What the Fair Work Commission actually published
In late August the Commission published its final Guidance Note on the use of generative AI in Commission cases, signed off by President Justice Adam Hatcher. It commences on 20 October 2026 and applies to all individual rights matters — unfair dismissal and general protections claims — and to self-represented parties and lawyers alike. It does not ban AI. The tone is deliberately practical: use the tools, but own what comes out of them.
There are three requirements. Disclose that you used generative AI and how. Verify the document — check that every factual statement, piece of evidence, legislative reference, case citation and quotation is accurate and genuinely exists. And where a witness statement is prepared with AI, the witness must review it so it reflects their own knowledge and words, not the model's. The Note is backed by a research report (18 interviews, 408 applicant surveys and 211 respondent surveys), and it lands against a workload Justice Hatcher has called "unprecedented" — driven, he says, principally by AI. We covered that surge when AI turned filing a claim into a ten-minute job.

Small businesses are the Commission's most frequent respondents. When a former employee files, it's usually the owner or the office manager who defends it — often without a lawyer, and increasingly with a chatbot open in the next tab. The other side is doing exactly the same. The Commission is now refereeing a contest in which both parties may be quietly leaning on the same tools, and it has decided it wants that on the record.
The risk was never using AI. It's using it unchecked. Generative AI invents case names, misstates the law, and embellishes facts with total confidence. More than 20 Australian court cases since 2024 have turned on AI-fabricated citations — in one, a lawyer had their practising certificate restricted over it. In a Fair Work matter, a made-up authority doesn't just get struck out; it tells the person weighing whether your dismissal was fair that your paperwork can't be trusted. If you're not sure how much of your business already runs on unverified AI output, see where your exposure sits.
What to do before 20 October
If you use AI in any Fair Work document — a response, a submission, a witness statement — do three things. Say you used it. Check every claim, section number, case name and quote against the primary source, not the chatbot that produced it. And for a witness statement, make sure the words belong to the witness, not the model. None of this is hard; it just has to actually happen before the document is lodged.
The wider lesson outlasts this one tribunal. The same disclose-and-verify discipline belongs on anything AI drafts that a customer, a court or a regulator will read — quotes, contracts, advice, marketing. A human checking AI output before it leaves the building is the cheapest insurance in the business. If you'd rather build that habit deliberately than learn it in a hearing, a short conversation will show you where to start.
Key takeaways
Common questions
Can I use AI to prepare a Fair Work claim or response?
Yes. From 20 October 2026 you may use generative AI to help prepare Fair Work Commission documents, but you must state that you used it and verify that every fact, case citation and quotation is accurate and genuinely exists before you lodge.
What happens if AI invents a case citation in my Fair Work submission?
You are responsible for it. The Commission has already dealt with a matter where an applicant's AI-generated citations did not exist. A fabricated authority can be struck out and, more damagingly, undermines your credibility with the member deciding your case.
Do the new AI rules apply to small businesses without lawyers?
Yes. The Guidance Note applies to all individual rights matters — unfair dismissal and general protections — and to self-represented parties and lawyers alike, from 20 October 2026.

▶Assumptions & methodology
- The Fair Work Commission's final Guidance Note: Use of Generative Artificial Intelligence in Commission cases was published in late August 2026 (issued by the week of 25 August 2026) and commences on 20 October 2026. Its scope (all individual rights matters, including unfair dismissal and general protections), the three requirements (disclosure, verification, and witness-statement authenticity), and the President's characterisation of workload growth are as set out on the Commission's website and reported by Human Resources Director (August 2026).
- The figure that Commission Members identified signs of generative AI use in 50 to 75 per cent of cases refers to the six months to March 2026, per the Commission's commissioned research report (a Pivot Management Consulting study comprising 18 interviews, 408 applicant surveys and 211 respondent surveys). The unfair dismissal matter involving non-existent AI-generated citations is referenced in that reporting.
- The draft Guidance Note was released for consultation on 24 March 2026 and drew 28 submissions before the final version; the final materials emphasise responsible use rather than prohibition.
- Last reviewed 28 August 2026. General information, not legal advice — confirm your obligations with the Fair Work Commission or a qualified adviser before relying on them.
