Request an internal review of an NDIS decision

A letter asking the NDIA to review a decision you disagree with — the first step before the Administrative Review Tribunal.

Who it's for

This letter is for participants, families and nominees who disagree with a decision the NDIA has made, such as the supports approved in a plan, the amount of funding, or eligibility. Asking for an internal review, formally a 'review of a reviewable decision', is the first step if you think a decision is wrong.

It's for anyone who wants the NDIA to look again. You don't need a lawyer, and a free advocate can help you prepare it. If you're still unhappy after the internal review, you can take the matter to the Administrative Review Tribunal.

Why write it

An internal review is your formal way of saying, 'please reconsider this decision.' A different NDIA officer looks at your case fresh, so a clear, specific letter gives them the best chance of understanding what went wrong and putting it right.

You generally have three months from the date of the decision to ask for a review, so it's important not to delay. A well-argued request can resolve the issue without needing to go to the Tribunal, which saves you time, stress and uncertainty while getting the supports you need sooner.

How to write it

Say clearly which decision you want reviewed and when it was made, then explain specifically why you think it's wrong. Vague disagreement is hard to act on; point to the exact supports or findings you disagree with and give your reasons.

Attach any new evidence, such as recent allied-health reports, that supports your case, and connect each point to your disability's functional impact and your goals. Keep the tone calm and factual.

Lodge within the timeframe, keep a copy of everything, and note the date you sent it. If you're unsure, contact a free disability advocate, who can help you write the letter and understand your options at no cost.

How do I request an internal review of an NDIS decision?
Contact the NDIA and ask for a 'review of a reviewable decision', explaining which decision you disagree with and why. You can do this by phone, in writing, by email, or at an NDIA office or local area coordinator. Attach any new evidence, and lodge within three months of the decision. A free advocate can help.
How long do I have to ask for an NDIS internal review?
You generally have three months from the date of the decision to request an internal review. It's best to act quickly so you don't miss the window and so your case is fresh. If time is tight, lodge your request and let the NDIA know more evidence will follow, keeping a record of the date you submitted.
What happens if I'm not happy with the internal review?
If you disagree with the outcome of the internal review, you can apply to the Administrative Review Tribunal (ART) for an independent review. The internal review is the required first step before the Tribunal. A free disability advocate can help you understand the process and prepare your case at no cost to you.
Can I get help writing an NDIS review request?
Yes. Free, independent disability advocates can help you understand the decision, gather evidence and write your review request. You don't need a lawyer for an internal review. Support from an advocate can make your letter clearer and stronger, and help you feel more confident throughout the process. Search for an advocacy service in your area.
What evidence should I include with an internal review request?
Include any new or updated evidence that supports your case, such as recent reports from an occupational therapist, physiotherapist, GP or specialist. Focus on evidence that shows how your disability affects everyday function and why the support you're requesting is reasonable and necessary. Clearly link each piece of evidence to the part of the decision you disagree with.
