Dealing with the NDIS can be tricky at times, and when things don't go to plan with a provider or a decision, it's easy to feel a bit lost. Here's the most important thing to remember: you have a protected right to complain. The NDIS complaints process exists to make sure your services are safe, high quality, and what you signed up for.
Your right to complain
Lodging a complaint isn't about being difficult. It's a fundamental part of the NDIS that protects you, holds providers and the agency accountable, and helps make the whole system better. And you're not alone: the NDIS Commission handles a large and growing volume of feedback every year, a healthy sign that more people feel confident to speak up when a service isn't right.
Every registered provider is held to clear quality and safety benchmarks, and knowing what those look like makes it easier to spot when something falls short. Our guide to the disability service standards explains exactly what you're entitled to expect.
Who to contact with your complaint
Getting this right from the start saves a lot of time. Your complaint will almost always go to one of two places: the NDIS Quality and Safeguards Commission, or the National Disability Insurance Agency (NDIA).
| Type of issue | NDIS Commission | NDIA |
|---|---|---|
| Service quality | Yes, if a provider's service is poor, unreliable or not what was agreed | No |
| Safety and respect | Yes, if you feel unsafe, disrespected or have been harmed by a provider | No |
| Plan funding | No | Yes, if you disagree with the funding amount in your plan |
| Plan decisions | No | Yes, if you're unhappy with what supports were (or weren't) approved |
| Provider conduct | Yes, for issues like privacy breaches or breaches of the NDIS Code of Conduct | No |
| Agency delays | No | Yes, if you're experiencing long delays from the agency itself |
In short, if your problem is about the quality or safety of a service you receive, go to the NDIS Commission. If it's about the funding or decisions in your NDIS plan, contact the NDIA.
When to make a complaint
Whenever a service isn't up to scratch, a decision feels unfair, or your rights have been overlooked. No issue is too small if it's affecting your wellbeing. You would contact the NDIS Commission for things like:
- Your support worker constantly shows up late or cancels at the last minute.
- You feel belittled, ignored or unsafe with a provider's staff member.
- The services you're receiving don't match your service agreement.
- Your provider shared your personal information without consent.
You would raise these kinds of issues with the NDIA:
- The funding in your new plan isn't enough to meet your needs.
- A support you rely on, like assistive technology or a therapy, wasn't approved.
- You're unhappy with how your plan reassessment was handled or with the outcome.
- You've been waiting weeks for a decision or response from the agency.
How to build a strong case
Before you fire off a complaint, get your ducks in a row. A complaint backed by solid evidence isn't just a grievance; it's a clear, credible account that's tough to dismiss.
Create a clear timeline of events
Start with a simple log of events in order. For each one, jot down the date and time, a brief factual note on what occurred, who was there, and where it took place. Say your issue is a support worker who is constantly late:
- 12 August: Support scheduled for 9:00am. The worker arrived at 9:45am and I missed my physiotherapy appointment.
- 19 August: Support scheduled for 9:00am. The worker arrived at 9:30am.
- 26 August: No one showed up. The provider said the worker was sick but hadn't arranged a replacement.
This shifts your complaint from a vague "they're always late" to specific, documented examples of where the service fell short.
Gather your important documents
If your timeline is the skeleton of your case, your documents are the muscle:
- Your service agreement. It spells out the supports, standards and schedules you both agreed to, so any gap between that agreement and the service you received is a powerful point in your favour. Our guide to your NDIS service agreement explains what should be in it.
- Emails and letters between you and the provider about the problem.
- Text messages. A quick screenshot is time-stamped, hard-to-dispute proof.
- Invoices and statements, which can show billing errors.
- Photos or videos where relevant, such as unsafe equipment or a damaged item.
Organise the documents so they line up with your timeline and your submission will be clear and easy to act on.
Lodging a complaint with the NDIS Commission
Once your evidence is together, the most direct route for many people is the online complaint form on the NDIS Commission website, a guided process that lets you lay everything out and attach your evidence. Three tips:
- Get specific. Vague statements like "the service was bad" won't get you far. Use your notes: "On 1 May, 8 May and 15 May, the support worker arrived 45 minutes late, and I missed my physiotherapy appointments."
- Stick to the facts. Let your timeline and documents do the talking.
- Explain the impact. Did it create an unsafe situation? Cost you money? Cause distress? A real consequence gives your complaint weight.
If you'd rather talk it through with a real person, call the NDIS Commission on 1800 035 544, and have your timeline in front of you because it's easy to forget details on the spot. You can also complain anonymously. However you lodge it, the goal is the same: a clear, factual, complete account of what went wrong.
Complaining about your NDIS plan or funding
When the issue is the plan itself, it's a different road. If your funding doesn't add up, an important support was rejected, or the planning process left you feeling unheard, your complaint goes directly to the NDIA. They build and fund your plan, so only they can change it, and taking a funding issue to the Commission will just slow things down. You can lodge a complaint through the online form at ndis.gov.au, by calling 1800 800 110, or at a local NDIA or partner office.
The NDIA's internal review process
If you disagree with a decision the NDIA made, what you're really requesting is an internal review: a staff member who had nothing to do with the original decision takes a fresh look. You generally need to ask within three months of receiving the decision, so don't sit on it.
To give your review the best chance, explain why you believe the decision was wrong and connect it to your disability needs and plan goals. Instead of "I need more transport funding", try: "My current transport funding covers three trips a week, but my plan goals include my weekly art class and two volunteer shifts, which requires five." That level of detail makes all the difference.
If your concerns touch on the reassessment process itself, our guide to getting a good outcome from your plan reassessment is worth a read, and our NDIS overview is a handy refresher on how the pieces of the scheme fit together.
What happens after you lodge a complaint
You should get an acknowledgement quickly, usually by email or letter, with a unique reference number. Keep it safe; you'll need it for any calls or emails down the track.
Your complaint then lands with a case officer, who reviews your timeline and evidence and asks three things: is this something we can deal with, what's the level of risk to the participant, and what does a good outcome look like? They'll often get in touch to clarify details, which is a good sign your complaint is being actively worked on. From there, the Commission or NDIA might contact your provider to hear their side (anonymously, if you asked), ask the provider to sort the issue out with you directly, or suggest conciliation, a meeting with you, your provider and a neutral third party.
You're in the driver's seat throughout, and you never have to accept a solution that feels unfair. Sometimes a genuine apology and a commitment to do better is enough. In other cases a provider may be required to update their policies, organise extra staff training, refund incorrect charges, or change how they deliver your supports. Speaking up can lead to real, lasting change.
Still unhappy with the outcome?
A decision that doesn't sit right isn't necessarily the final word. Your first move is usually to request an internal review of the complaint outcome, whether it was handled by the Commission or the NDIA. You're asking for a second opinion from someone senior who had nothing to do with the first decision. If that doesn't fix it, you can go to an independent external body:
- The Commonwealth Ombudsman handles complaints about how the NDIA or the NDIS Commission managed things. Did the agency act fairly, follow its own rules, and behave reasonably?
- The Administrative Review Tribunal (ART) is where you go if your issue is an NDIA decision about your plan and the internal review didn't resolve it. The ART, which took over from the older appeals tribunal in late 2024, can take a completely fresh look at the decision and has the power to change it.
Approaching either body takes the same preparation as your first complaint, so keep your timeline and evidence organised. For an ART application, it's worth having support in your corner; a disability advocacy service or legal aid can help you prepare and knows what kind of evidence makes an impact. Most importantly, don't give up. These escalation pathways exist so there's always a way forward to a fair outcome.
