How to request an NDIS internal review

You can ask the NDIA to review most decisions, including plan decisions. This is called an internal review. Ask within 3 months of receiving the written decision. It's free, and you must do this before going to the tribunal.

What to include in your request

  • The decision you want reviewed, its date and reference
  • Why it's wrong, support by support
  • How each support meets the reasonable and necessary criteria
  • Your evidence: reports, letters, a carer statement and a support diary
  • A request for the reasons and documents the decision relied on

Tips

  • Lodge on time, even if some reports are still coming. You can send more evidence later.
  • Be specific: hours, frequency and what happens without the support.
  • Keep copies and note the date you lodged.

If you still disagree

If you disagree with the internal review decision, you can apply to the Administrative Review Tribunal (ART) within 28 days of receiving it. The ART may allow more time in some circumstances. Free help is available through the NDIS Appeals Program.
