NDIS Review of a Decision: How to Appeal

You opened your NDIS plan, or a letter from the NDIA, and your heart sank. The funding is not what you hoped for, a support you rely on has been cut, or your access request was knocked back. If that is where you are, take a breath. An NDIS decision is not always the final word, and you have a clear, fair process you can use to challenge it.

This guide explains how to seek a review of an NDIS decision in plain English. We will walk through the two main stages, how to gather evidence, where to get help, and how to keep yourself calm and organised along the way.

First, Know That You Have the Right to Disagree

Many NDIS decisions can be reviewed. These are called reviewable decisions, and they include things like whether you meet the access requirements, what supports are funded in your plan, and how your plan is managed.

The most important thing to understand is that there are two stages if you disagree:

1. An internal review by the NDIA (officially called a "review of a reviewable decision")
2. An external review by the Administrative Review Tribunal (ART) if you are still unhappy after the internal review

You generally cannot skip straight to the external stage. You start with the internal review, and only if you remain dissatisfied do you go to the ART. Let's look at each.

Stage One: Request an Internal Review

An internal review means asking the NDIA to look at its own decision again, with a different staff member who was not involved the first time. This is your first and often quickest avenue.

What to Do

• Act within the timeframe. You generally need to request an internal review within a set period after you receive the decision. Because these timeframes can change, check the current limit on ndis.gov.au or in your decision letter, and do not sit on it. The sooner you start, the better.
• Put it in writing. You can request a review by phone, in writing, or using the NDIA's form. Putting it in writing gives you a clear record. State the decision you disagree with and why.
• Be specific. Explain exactly what you think should be different and the reasons. "I disagree with my whole plan" is weaker than "the funding for support coordination does not reflect the complexity of my situation, because..."

What Happens Next

A different NDIA decision-maker reviews the original decision and can confirm it, change it, or set it aside. They should consider any new information you provide, which is why the evidence you gather (more on that below) matters so much.

If the internal review goes your way, brilliant. If it does not, or if it only partly fixes things, you can take the next step.

Stage Two: External Review at the ART

If you are still unhappy after the internal review, you can apply for an external review at the Administrative Review Tribunal (ART). The ART is independent of the NDIA. It replaced the Administrative Appeals Tribunal (AAT), so if you see older information mentioning the AAT, the ART is the body that now handles these reviews.

A few things to know:

• There is a timeframe here too. You generally need to apply to the ART within a set period after the internal review outcome. Check the current timeframe on the ART or NDIS website rather than relying on a number that may have changed.
• It is designed to be accessible. The ART aims to be fair and not overly formal. You do not need to be a lawyer, and there are usually steps along the way, such as case conferences, where things can be resolved before any formal hearing.
• Free support is available. There are funded advocacy and legal assistance services to help people through the ART process, so you do not have to pay for expensive representation.

The ART takes a fresh look at the decision and reaches its own conclusion about what is correct. That is why strong, clear evidence is just as important here as at the internal stage.

Gathering Evidence That Actually Helps

Whichever stage you are at, your evidence does the heavy lifting. A review is not about who argues loudest. It is about showing that the support you are asking for is reasonable and necessary and connected to your disability.

Strong evidence often includes:

• Reports from your treating professionals, such as your GP, specialists, therapists or psychologist, describing your disability and its impact
• Functional assessments that show what you can and cannot do day to day, and what support changes that
• A clear picture of a typical week, including the hard days, not just the good ones
• Letters or statements from people who know you well, and evidence of what has changed since your last plan

One tip makes a real difference: ask your professionals to link their comments directly to the support you are requesting. A report that says "Jess would benefit from X support because of Y" is far more useful than a general summary. Our guide on how to prepare for a plan review covers evidence-gathering in detail, and much of it applies here too.

If part of your disagreement is about whether a particular support should be funded, it can help to understand the rules first. Our guides on what NDIS funds can be used for and the NDIS funding categories explain what tends to be considered reasonable and necessary, so you can frame your case clearly.

Getting Help From an Advocate

You do not have to do this on your own, and you should not feel you have to. An independent advocate can help you understand the decision, prepare your case, and even speak on your behalf.

• Disability advocacy is often free. There are advocacy organisations across South Australia that help people with disability with NDIS issues, including reviews and appeals.
• You can find one through the Disability Advocacy Finder on the Ask Izzy or Department of Social Services websites, or by searching for advocacy services in SA.
• At the ART stage, there are also legal assistance services specifically for NDIS matters.

A good advocate has been through this many times. They know what the NDIA and the ART look for, and having someone calm and experienced beside you takes a lot of the pressure off.

Staying Calm and Organised

Challenging a decision can feel stressful, especially when it is about supports you genuinely need. A few habits make the whole thing more manageable.

• Keep everything in one place. Save your decision letters, review request, evidence and correspondence in a single folder, paper or digital.
• Write down dates. Note when you received each decision and the deadline for your next step, so nothing slips past you.
• Keep a record of phone calls, including who you spoke to, when, and what was said.
• Take it one stage at a time. You do not have to solve everything today. Lean on your support network, and be kind to yourself along the way.

How a Support Coordinator Can Help

A support coordinator cannot lodge an appeal for you, and we do not provide legal or advocacy services. But the right support coordinator can be a genuine help around the edges of a review, and that support can make a stressful time easier.

At Navigator In Reach, we provide support coordination only, and within that role we can:

• Help you make sense of the decision and point you towards advocacy and legal assistance services in South Australia
• Help you gather and organise provider reports and evidence, so your case is well put together
• Keep your existing supports running while the review is underway, so you are not left stranded
• Help you prepare for what comes next, including your next plan review

If you want to understand the role more fully, our overview of what support coordination is lays it out. Knowing you have someone organised in your corner can make a real difference when you are tired and frustrated.

Frequently Asked Questions

How long do I have to ask for a review? There are set timeframes for both the internal review and the ART stage. Because these can change, check the current timeframes on ndis.gov.au or in your decision letter, and act promptly.

Do I need a lawyer to go to the ART? No. The ART is designed to be accessible without legal representation, and free advocacy and legal assistance services are available if you want support.

Will my current supports stop while I appeal? Your existing plan generally continues while a review is underway. If you are worried about a gap, raise it with the NDIA or your support coordinator straight away.
