If you disagree with a decision the NDIA has made about your plan, your funding, or anything else you have the right to challenge it and decisions do get overturned.

Step one: internal review. Ask the NDIA to review the decision within three months of receiving it. A different decision-maker looks at it fresh. This is the moment to add supporting evidence like reports, quotes or else anything that strengthens your case.

Step two: the Administrative Review Tribunal (ART). Still unhappy after the internal review? You can take the decision to the ART, an independent tribunal that checks government decisions are fair. (Older information may mention the AAT  the ART replaced it in 2024.)

Along the way: free advocacy services can support you through both stages and you can keep using your current plan while a review is underway.
