Evidence for an NDIS Appeal
Strengthen your NDIS appeal with functional evidence, up-to-date reports and concrete examples that show how your disability affects daily life.
Strong evidence is the heart of any successful NDIS appeal. The agency decides what's reasonable and necessary based on what it can see about your disability and daily life — so your job is to show that clearly. The good news is you don't need legal arguments, just honest, up-to-date, real-world evidence. Here's how to build a case that speaks for itself.

Frequently asked questions
What is functional evidence?
Functional evidence describes how your disability affects the everyday things you do — daily tasks, what you can manage alone, where you need support, and the impact on your safety and independence. A diagnosis says what your condition is; functional evidence shows what it means for your life, which…
What kind of evidence is most persuasive?
Up-to-date reports from professionals who know you, functional evidence about your daily life, and concrete real-life examples. Quality beats quantity — a few strong, relevant, recent pieces are more effective than a large, unsorted pile. Aim to connect each support to the reasonable and necessary…
Do my reports need to be recent?
Where possible, yes. Older reports may not reflect your current situation, and needs change. Ask professionals to refresh reports so they describe how things are now, and to be specific about function and support needs, not just the diagnosis. Report-writing takes time, so ask early.
What does 'reasonable and necessary' mean?
It's the NDIS test for funding a support. Broadly, the support should relate to your disability, help you pursue your goals and take part in daily life, represent value, and be the kind of thing the NDIS funds rather than another system's responsibility. Strong evidence connects your support to this…
Can I add my own examples as evidence?
Absolutely. Plain, honest examples of a typical day — what happened, what support you needed, and what the day looked like without it — are powerful evidence only you can give. They make your situation concrete in a way general statements can't.
Who can help me put my evidence together?
A disability advocate or support coordinator can help you decide what to include and how to present it, and this help is free. Our guides Using a disability advocate and Getting help with an appeal show you how to find support.
