How do I appeal an NDIS decision?

Step-by-step guide to appealing an NDIS decision — from internal review to the Administrative Appeals Tribunal.

If you disagree with an NDIS decision — about your plan, your funding, or your eligibility — you have the right to appeal. Here's how the process works.

Step 1: Request an internal review

You can ask the NDIA to review any decision. This is called an internal review.

  • You must request it within 28 days of receiving the decision
  • You can do it online through the NDIS portal, by phone, or in writing
  • A different NDIA staff member will review the decision

Step 2: Get support for your review

You don't have to do this alone. Free support is available:

  • Disability Advocacy Finder — search at disabilityadvocacyfinder.org.au
  • NDIS Appeals Support — funded advocates who can help you prepare and present your case
  • Your support coordinator — can help gather evidence

Step 3: Gather evidence

The strongest reviews include:

  • Letters or reports from your therapists, doctors, or specialists
  • Evidence showing why the decision doesn't reflect your needs
  • A clear explanation of what outcome you want and why

Step 4: If the internal review doesn't help — appeal to the AAT

If the internal review doesn't change the decision, you can appeal to the Administrative Appeals Tribunal (AAT).

  • You have 28 days from the internal review decision to apply
  • The AAT is independent of the NDIA
  • You can get free legal help through the NDIS Appeals program

Key tips

  • Don't miss the 28-day deadlines — they're strict
  • Get an advocate — it significantly improves your chances
  • Keep copies of everything — letters, emails, and decisions
  • Ask for reasons — you can request a written explanation of any NDIS decision
