What are the NDIS eligibility criteria?

The NDIA looks at age, residence, and either the disability requirements or the early intervention requirements. You apply while younger than sixty-five, meet residence rules, and show a permanent, significant impairment or an early intervention need. The NDIA weighs each application against these published criteria itself.

What is the age limit for the NDIS?

You need to be younger than sixty-five on the day you apply. People aged over that who are not already participants are generally directed to aged care instead. Someone already in the scheme who turns that age can usually choose to stay, within the scheme's rules.

What counts as a permanent disability?

The criteria look for an impairment that is likely permanent, usually assessed once available treatment has been considered, and that substantially reduces everyday function in areas like communicating, moving, learning, or self-care. Evidence from your treating professionals is what shows this, not a diagnosis label on its own.

What is early intervention eligibility?

It is a separate path for people, including young children with developmental delay, where support now can improve function or stop it worsening. You still meet age and residence rules, and evidence from a treating professional shows the early support would make a real difference to daily life.

Does meeting the criteria guarantee access?

No. These are the things the NDIA looks at, not a decision you can make yourself. The NDIA weighs your evidence against its published criteria and decides. Reading the criteria helps you prepare a strong application, but the outcome always rests with the agency, case by case.

NDIS Eligibility: What the NDIA Looks At

NDIS eligibility rests on a small set of published criteria: your age, where you live, and whether you meet the disability requirements or the early intervention requirements. Understanding them helps you prepare, but they describe what the NDIA weighs, not an answer you can settle yourself.

Nothing on this page decides or predicts an access outcome. It explains the published criteria so you know what the NDIA looks at. With that framing set, here is what each requirement actually asks.

Age: the sixty-five cut-off

Age is the first thing the criteria check. You need to be younger than sixty-five on the day you apply. People aged over that who are not already in the scheme are generally pointed towards aged care supports instead, which is a different system with its own rules.

Age also shapes how you apply, not just whether you can. Children under nine are supported to apply through the early childhood approach, which is built around younger children and their families rather than the standard adult route. Someone already in the scheme who reaches the cut-off age can usually choose to stay, within the scheme’s rules about aged care.

Residence: who can apply from where

The residence requirement looks at your status and where you actually live. You need to be an Australian citizen, a permanent resident, or a Protected Special Category visa holder, and you need to live in Australia and spend most of your time here.

Living here is part of the test, not just holding the right status. Residence is usually confirmed through a Centrelink record with your consent, or through documentary evidence like citizenship or visa papers. Travel is allowed, and there is a short grace period for using supports overseas, but staying away beyond it means checking with the NDIA in advance.

Disability requirements: what the evidence has to show

The disability requirements are where most of the assessment happens, and they turn on evidence rather than a label. The criteria look for an impairment that is intellectual, cognitive, neurological, sensory, or physical in nature, and that is likely permanent, usually assessed once available and appropriate treatment has been considered.

That impairment also has to substantially reduce your functional capacity in everyday areas, such as communicating, socialising, learning, moving, or managing daily life. And it has to create a need for support, whether that is significant help from other people or assistive technology and home changes prescribed by a health professional. Evidence from your treating professionals, written to answer these questions, is what shows the criteria are met.

Early intervention: the other path in

Early intervention is a separate route to access, and someone can meet it alongside the disability requirements. It exists for situations where getting support now improves function, prevents it from worsening, or builds the skills of the family and carers around a person.

Age and residence still apply, and evidence from a doctor, specialist, or treating professional is still needed. The path matters especially for young children, since early intervention is also available for children under six with developmental delay, and children with developmental concerns can access early supports through the early childhood approach without becoming a participant straight away.

How to use the criteria

Read these criteria as a preparation tool. They tell you what evidence to gather and what questions your reports should answer, which is exactly how you build a strong application. What they do not do is hand you a verdict.

The NDIA publishes its access criteria, and the NDIA alone decides who becomes a participant. The criteria and application process are on the official NDIS website. When you are ready to act on them, how to apply for the NDIS walks through the access request step by step, and how NDIS funding works covers what a plan looks like once access is granted. The Plans & Budgets guide follows the whole path, and the eligibility walkthrough steps through what the NDIA looks at.

General information only, not advice. NDIS access depends on your individual situation and the NDIA’s decision. Confirm anything that matters with an NDIS partner or the official NDIS website.
