The biggest barrier to NDIS support is often not a disability, it is the paperwork. If you are trying to work out whether you or someone you love is eligible, this guide breaks the 2026 access rules into plain language.
The five things the NDIA checks
The National Disability Insurance Agency sets out its eligibility test in five steps on its own page, how to check your eligibility (current as of 9 June 2026). Everything below follows that page, because it is the only version that counts when someone assesses your application.
- Identity. The NDIA asks for three different identity documents showing your name, address, date of birth and a photo. It asks the same of a child representative, nominee or authorised representative.
- Age. You must be younger than 65 on the day you make your application.
- Residence. You must be an Australian citizen, or hold a permanent residency visa, or hold a Protected Special Category visa. You must also live in Australia and spend most of your time here.
- Disability requirements. You have one or more impairments likely to be permanent, which substantially reduce your ability to do daily activities, and you will likely need NDIS supports for life.
- Early intervention requirements. A separate path, for people whose impairments are likely permanent and where support now would reduce the support they need later.
That last point matters more than most families realise. There is more than one way in. You can be eligible under the disability requirements, the early intervention requirements, or both.
The age rule is not what most people think
There is no lower age limit. The commonly repeated idea that a child has to reach a certain age before the NDIS will look at them is wrong.
What is true is that children come in through a different door. The NDIA calls it the early childhood approach, and it covers children younger than 9. Within that, it helps children younger than 6 with developmental delay, and children younger than 9 with disability, along with their families.
At the other end, the cut off is hard. You must be younger than 65 on the day you apply, which means a complete application, in the format the NDIA asks for, received before your birthday. If someone in your family is turning 65 within the year and might be eligible, that is a this month job, not a next year job. The NDIA asks people in that position to contact it so it can help them apply on time.
Residence, in the exact words that are used
This is where advice from friends goes wrong most often, so it is worth being precise. The NDIA accepts three statuses: Australian citizenship, a permanent residency visa, or a Protected Special Category visa, which is only for some citizens of New Zealand.
A permanent humanitarian visa is a permanent residency visa, so a family who arrived as refugees and holds one generally meets this test. A temporary visa does not meet it, whatever the circumstances behind it. If your household is somewhere in between, or you are mid application for permanent residency, that is worth checking properly rather than assuming, and our guide to NDIS applications for refugees and newly arrived families goes through it in more detail.
You also have to actually live here. The NDIA can check both your age and your residence against your Centrelink record with your consent, which saves you finding documents. Without consent you supply the evidence yourself: a birth or arrival document such as a full birth certificate, passport or citizenship certificate, plus evidence you live in Australia.
What 'permanent and significant' really means
This is where many applications stall. The NDIS is not interested only in your diagnosis. Read the disability requirements closely and they are all about function: one or more impairments likely to be permanent, substantially affecting your ability to do daily life activities, and affecting your social life or your ability to work or study.
So the question an assessor is really asking is not "what condition does this person have" but "what can this person not do without help, on an ordinary day, and will that still be true in five years". A diagnosis alone rarely answers that. The story of your day to day life is what carries the application.
Gather the right evidence, and start early
The NDIA says plainly that you should start collecting evidence before you apply, and that it will need evidence about your impairments and how they affect your daily life: assessments, reports, and written statements.
In practice that means:
- Recent reports from specialists who know you well, written to describe function and impact rather than only naming a condition.
- Written statements from you and the people around you, covering the ordinary week rather than the best day.
- Notes on the invisible work: prompting, supervising, planning, managing appointments, the help that does not feel like support until you count the hours.
Start gathering this earlier than feels necessary. Getting a report rewritten so it describes impact rather than diagnosis takes weeks, and specialist appointments take longer than that.
Support in your language
If English is not your first language, you are not on your own in this. Interpreting for the NDIS is delivered by TIS National, and the NDIA states that NDIS participants and carers are not charged for language interpreting services (that page current as of 3 May 2026). You can call TIS National direct on 131 450, or ask to speak to the NDIS on 1800 800 110.
Preparing with someone who knows both the paperwork and your community helps too, and our guide to culturally safe support in the NDIS covers what that looks like beyond language alone.
We can help before you apply
A short conversation before you apply can save months. An application is rarely knocked back because the person was ineligible. It is knocked back because the evidence described a condition instead of a life.
We help families across Western Sydney read the requirements against their own situation, work out what evidence is missing, and approach the first conversation with the NDIA prepared. Reach out and we will walk you through it.
