If you already get disability support, the NDIS should let you know when the NDIS is going to be in your area and they'll send you the right form, called the Access Request Form. This is a special form that tells the NDIS about you that we need to know for the NDIS.
But if you're not getting disability support at the moment and you'd like to speak to the NDIS about getting it, you can call them on 1800 800 110.
