Getting a letter from the NDIA that does not go the way you expected can be stressful, especially if it affects funding or supports you rely on every day. The good news is that you do not have to simply accept a decision you disagree with. There is a clear process for how to appeal an NDIS decision, and understanding the steps involved can make it feel far less overwhelming.
This guide walks through what counts as a reviewable decision, how the internal review process works, and what happens if you need to take things further to the Administrative Review Tribunal. None of these steps require legal training, but knowing what to expect at each stage makes the whole process much easier to manage.
What Counts as a Reviewable NDIS Decision?
Not every letter or update from the NDIA can be formally reviewed, but many important ones can. Reviewable decisions NDIS participants commonly want to challenge include access decisions (whether you are eligible for the scheme), plan decisions (what supports and funding are included), and decisions about plan reassessments.
Your decision letter should tell you whether the outcome is reviewable and how to request a review. If you are unsure, it is worth checking the letter closely or asking your support coordinator or planner to confirm before you proceed.
Request an NDIS Internal Review
The first step is always an NDIS internal review. This involves a different NDIA staff member, someone who was not involved in the original decision, taking a fresh look at your case. You generally have three months from the date you receive the decision to ask for this review, so it is worth acting sooner rather than later.
You can request an internal review online, by phone, or in writing, and it helps to include any extra information that supports your case, such as reports from your doctor, therapist, or support worker.
What Happens During an Internal Review?
Once your request is received, the NDIA has 90 days to complete the internal review, unless a different timeframe is set out in the rules for your situation. The reviewer will look at all the information available, including anything new you have provided, and will not simply rubber-stamp the original decision.
At the end of the process, there are three possible outcomes: the original decision is confirmed, it is varied (partly changed), or it is set aside and replaced with a new decision. You will receive a letter explaining the outcome and the reasons behind it, and it is worth reading this closely, since it will shape any further steps you decide to take.
If the NDIA does not complete your internal review within the required timeframe, you may be able to apply directly to the ART without waiting any longer, so it is worth noting the date you submitted your request.
Disagreeing with an NDIS Decision After Internal Review
If you are still disagreeing with an NDIS decision after the internal review, you are not out of options. This is where the Administrative Review Tribunal, often shortened to the ART, comes in. You can only request one internal review of a particular decision, so the ART is the next and final avenue if you remain unhappy with the outcome.
It can help to sit with the internal review letter for a moment before deciding what to do next. Understanding exactly why the decision was made, not just what the decision was, makes it much easier to prepare a strong case for external review.
Applying to the Administrative Review Tribunal
The Administrative Review Tribunal NDIS matters go to is a body that sits completely separate from the NDIA. It reviews the internal review decision on its merits, meaning it looks at whether the right decision was made, not just whether the NDIA followed the correct process.
You generally have 28 days from receiving your internal review decision to lodge an application with the ART. Applications can be made online, by post, or by writing a letter, and there is no fee to apply for a review of an NDIS decision. The Tribunal will ask both you and the NDIA to provide information and may hold a hearing, though many matters are resolved without needing to go that far.
Hearings, when they do happen, are generally less formal than a courtroom. You can bring a support person, an advocate, or a family member with you, and the Tribunal member’s role is to understand your situation and reach a fair outcome based on the evidence before them.
Getting Support Through the Review Process
Knowing how to appeal an NDIS decision is one thing, but having the right people around you while you do it makes a real difference. Family members, carers, advocates, and support coordinators can all help you prepare your case, gather evidence, and understand the letters you receive along the way.
Free advocacy and legal support is also available through the NDIS Appeals Program for people going through the ART process, which can be particularly useful if your matter is complex. If a nominee manages your plan, they should be kept informed and involved throughout, since they may need to act on your behalf at various stages.
