Something has gone wrong with your provider. Maybe they're consistently late. Maybe a support worker said something that made you uncomfortable. Maybe the service you're getting looks nothing like what was agreed. Whatever it is, you have the right to say so — and there's a clear process for doing it.

This guide walks you through every step: from raising it directly with your provider, to escalating to the NDIS Commission, to what you can do if you're still not satisfied.

You Have the Right to Complain — And It's Worth Doing

Complaining about a provider isn't making trouble. It's a right that exists specifically to protect NDIS participants — and one that often leads to real improvements, not just for you but for other people using the same service.

The NDIS Quality and Safeguards Commission exists to handle exactly this. They can investigate poor-quality services, unsafe practices, and providers who aren't meeting their obligations under the NDIS Code of Conduct. When people report problems, the Commission can take compliance action — which means your complaint can matter beyond your own situation.

You don't need a lawyer. You don't need to have everything perfectly documented. You just need to know the steps.

Step 1 — Raise It With the Provider First (If It's Safe To)

In most cases, the quickest path to fixing a problem is to raise it directly with the provider. All NDIS providers — registered and unregistered — are expected to have a way to receive and respond to complaints. Registered providers are legally required to have a formal complaints management system. If you're unsure what that process looks like, ask them for a copy — they're required to make it available.

When you raise a complaint, you can do it verbally (in person or by phone) or in writing (email works well because it creates a record). Be specific: what happened, when it happened, and what you'd like to see change.

A note on documentation: Keep a record of any concerns you raise, including the date, who you spoke to, and what they said. If the complaint escalates, this timeline will be useful.

A composite example of how this typically plays out: a participant notices their support worker has been arriving 30–45 minutes late to nearly every shift over several weeks. When they raise it with the provider's coordinator, the issue is attributed to scheduling problems — but after the conversation, punctuality improves significantly. That's the best-case outcome: a problem identified, resolved quickly, relationship preserved.

What if you don't feel safe raising it with the provider?

You are not required to raise concerns with your provider first. If the situation involves abuse, neglect, exploitation, or behaviour that makes you feel unsafe, go directly to the NDIS Commission. There is no rule that says you must give a provider a chance to respond before escalating.

The Commission's number is 1800 035 544 (free call from landlines). You can call anonymously if needed, and you can ask for an interpreter.

What if the provider doesn't respond or dismisses your complaint?

If you raise a complaint with your provider and they don't take it seriously, don't follow it up, or their response leaves you worse off — escalate to the NDIS Commission. That's exactly what the Commission is there for.

Step 2 — Lodge a Complaint With the NDIS Commission

The NDIS Quality and Safeguards Commission is an independent government regulator. It handles complaints about the quality and safety of NDIS-funded supports and services — it's separate from the NDIA, which manages your plan and funding.

NDIS Commission vs NDIA — what's the difference? The NDIS Commission handles complaints about providers and workers: the quality of support, how you're treated, breaches of the Code of Conduct. The NDIA (National Disability Insurance Agency) manages NDIS plans, funding decisions, and access to the scheme. If your complaint is about a plan decision or funding amount, contact the NDIA — not the Commission.

You can lodge a complaint with the Commission two ways:

• Online: Complete the complaint form at ndiscommission.gov.au
• Phone: Call 1800 035 544 (free call, Monday–Friday; interpreters available)

When you make a complaint, it helps to have:

• Your name and contact details (or choose to remain anonymous)
• The name of the provider or worker involved
• What happened and when
• What you've already tried to resolve it (if anything)
• What you'd like to see happen — an apology, a change in service, action taken against the provider

You can also provide supporting evidence: notes, photos, emails, reports.

What does the NDIS Commission actually handle?

The Commission can investigate complaints about:

• Services or supports that weren't delivered safely or to a reasonable standard
• A provider or worker who behaved inappropriately, used unfair practices, or took advantage of a participant
• 
  
• A provider who handled your complaint poorly Neglect, abuse, or situations where a participant's rights weren't respected. They cannot handle complaints about NDIS access decisions, plan funding amounts, or who does or doesn't have an NDIS plan — those go to the NDIA.

What if your provider is unregistered?

The Commission can still receive your complaint. Since 2018, the Commission has jurisdiction over both registered and unregistered providers. That said, unregistered providers aren't required to have a formal complaints process, so the Commission's options for escalation may be different. If you're unsure whether your provider is registered, you can check on the Commission's website.

What Happens After You Lodge a Complaint

Once you've lodged, the Commission will acknowledge receipt. For serious matters — where someone is at risk of harm — they treat it as urgent.

For other complaints, the process typically looks like this:

1. The Commission reviews what you've told them
2. They may contact you for more information
3. With your permission, they'll contact the provider about the complaint
4. They investigate and decide what action (if any) to take
5. They let you know the outcome

You can request that your identity be kept confidential — but this may limit what the Commission can do, since it becomes harder to investigate without disclosing why they're asking questions.

One thing worth knowing: providers are not allowed to treat you worse because you made a complaint. That's a breach of the Code of Conduct in itself. If a provider retaliates — by reducing your services, becoming hostile, or cancelling your agreement — that can be reported to the Commission as a separate matter.

A pattern that comes up regularly: a participant complains about a provider's billing practices — being charged for sessions that didn't happen, or for more hours than were delivered. After lodging with the Commission, the provider is contacted, required to provide records, and directed to refund the overcharged amounts. The participant is kept informed throughout. The process takes several weeks but resolves in the participant's favour.

If You're Still Not Happy — Escalation Options

If the Commission's response doesn't resolve things to your satisfaction, you have further options.

Request a reconsideration. You can ask the Commission to reconsider their decision. You have 42 days from being informed of the decision to make this request.

Contact the Commonwealth Ombudsman. If you're not satisfied with how the Commission handled your complaint — not just the outcome, but the process itself — the Ombudsman can review it.

Administrative Appeals Tribunal (AAT). If your complaint relates to an NDIA decision (about your plan or funding), and you've already requested an internal review through the NDIA, you can take it to the AAT. Call the AAT on 1800 228 333.

Get a disability advocate. Advocates are independent people who support you through the complaints process — they can help you understand your rights, draft letters, attend meetings with you, and speak on your behalf if needed. They don't work for the NDIS or any provider. Use the Disability Advocacy Finder at disabilityadvocacyfinder.dss.gov.au to find someone in your area.

A common scenario: a family lodges a complaint about a plan manager repeatedly making payment errors that affect the participant's services. The Commission acknowledges the complaint but the resolution doesn't address the full financial impact. With the support of an advocate, the family requests a reconsideration and is ultimately connected with the Ombudsman's office, which helps facilitate a resolution. Having an advocate significantly reduced how much the family had to manage on their own.

You Don't Have to Stay While You Wait

A complaint doesn't lock you into your current provider. You can change providers at any time — you don't have to wait for the complaint to resolve first.

If your service agreement has a notice period for ending services, check it — most registered providers are required to include one, and they must give you reasonable notice too. But if the situation is unsafe, you can leave more quickly and the Commission can advise you on your options.

If you're not sure where to start looking for a new provider, search over 20,000 verified NDIS providers on SupportSearch — filter by service type and location to find someone closer to what you need.

You can also use the SupportSearch Community Q&A to ask questions and get answers from verified providers directly — useful if you're not sure what to look for in a replacement, or want to understand what a good provider looks like in your category.

Changing providers is not giving up. It's using the choice and control the NDIS is built around.
