When the NDIS first came in, the change was pretty straightforward for some people. If you were already getting disability support through the state-run programs, you were shifted across into the new system almost automatically. That part was simple. But for others, especially people who weren’t already linked to funded supports, it meant applying from scratch. That’s when the word “eligibility” really started to matter, because you had to prove you fit the conditions before being accepted.
The scheme isn’t open to absolutely everyone. It has rules to make sure the funding goes to people who need support in the long term. And those rules come down to a few key checks. Age, residency, and disability needs. If you don’t meet those, you don’t get access.
You need to be under 65 at the time you make your access request. That’s the cut-off point. If you’re 65 or older, the support system available is aged care rather than the NDIS.
You have to live in Australia, and you need to tick one of the following boxes:
Those are the main ones. There are a few other details that sit inside the NDIS rules, but for most people, it’s one of the three.
This is the area where the most detail is looked at. You need to have a disability that links to an intellectual, cognitive, neurological, sensory, psychosocial, or physical impairment. It must be permanent, or at least very likely to be permanent. It must also have a big impact on your day-to-day life. That means difficulty with things like:
It’s not just about having a diagnosis written down. The NDIA looks at how the impairment affects your ability to take part in social or economic life. They also need to see that you’re likely to need NDIS supports across your lifetime. For children, the pathway is a little different—they might be considered under early intervention, where support is put in place early to reduce the long-term impact.
These rules aren’t there to make things harder for people. They’re there to make sure the scheme stays focused on those who need lifelong support. Meeting the eligibility criteria is what opens the door to funding, planning, and supports. It’s the first step in being part of the scheme.
If you’re not sure, you can always check the official NDIS eligibility checklist or read the NDIS Act 2013 where the rules come from. At Support Network, we explain this in simple language and guide people through the steps so they can see if they’re eligible.
