Chronic disease and sudden accidents do not discriminate by age. Still, the NDIS is not available to those who experience disability after the age of 65 years. The NDIS has a list of criteria for deciding eligibility, and the first question on their website states:
Question 1: Are you aged between 7 and 65? Yes. Go to the next question. No. I have a child aged under 7. Find out more about Help for children under 7. No. I'm over 65. You must be under 65 to access the NDIS. You may be able to access other supports.
