People who are already in certain state and territory programs will receive or will have received a call from the NDIA, the agency responsible for rolling out the NDIS, when the scheme becomes available. You will only receive this call (or only have received this call if your area has already transitioned onto the NDIS), if the program you receive support from is on the list of programs considered to have similar eligibility criteria to the NDIS. Otherwise, you will have to apply by contacting the NDIA directly.

You can also make a new application at any time (providing three months have passed since any formal rejection from the scheme), even if you were told at rollout that you were not eligible.
