What evidence do I need to prove my disability?

Before you can get the NDIS, the NDIS need to know some things about your diagnosis and how your disability affects your life. There's a bit on the form they'll give you that your doctor can fill in, or you can give the NDIS copies of reports you've gotten from medical professionals.
