NDIS eligibility and how to apply

The hardest part of the NDIS for most people is the beginning: working out whether you can get in at all, and what the process actually asks of you. The criteria are more specific than they first appear, and the thing that decides most requests is not the one people expect. This guide covers who the scheme is for, how to ask, what evidence carries weight, and what to do if the answer is no.

Three things are tested, not one

People tend to think of NDIS access as a single question about disability. It is actually a set of requirements, and all of them have to be met:

• Age — you generally need to be under 65 when you make your access request
• Residence — Australian citizenship, permanent residence, or a Protected Special Category Visa
• Disability or early intervention — the substantive test, covered below

The age requirement catches people out, because it is about when you apply rather than about the support you need. If someone is approaching 65 and might ever need the scheme, that is a reason to look into it now rather than later. Aged care is the pathway afterwards, and it is a different system with different funding.

What the disability test actually asks

This is the part most often misunderstood. The NDIS does not have a list of qualifying conditions that grants access automatically. What it assesses is whether you have an impairment that is likely to be permanent, and whether it substantially reduces your functional capacity in everyday life.

Functional capacity is assessed across areas such as mobility, communication, social interaction, learning, self-care and self-management. The question is not what your diagnosis is called — it is what you cannot do, or cannot do safely and reliably, without help.

Two people with the same condition can genuinely receive different answers, and that is not an inconsistency. It follows directly from a test about function rather than about labels.

The other door: early intervention

There is a second pathway that is easy to miss. Early intervention is for people where providing support now would reduce how much support is needed later — most commonly young children with developmental delay or disability, but not only them.

It matters because the reasoning is different. Under early intervention the case is not only about current functional impact but about what earlier support would prevent. For a young child in particular, a request framed this way can succeed where one framed purely around present limitation does not.

How to make a request

You can start by phoning the NDIA directly, or by working through a Local Area Coordinator or early childhood partner — and for a first-time applicant those partners are usually the easier route, because helping people through access is their job.

The request itself is a form plus supporting evidence. The form is manageable. The evidence is what decides the outcome.

The evidence is the whole thing

Most unsuccessful requests fail on evidence rather than on eligibility. What carries weight is documentation from treating health professionals that speaks specifically to permanence and to functional impact — not a letter confirming a diagnosis.

The distinction is worth being blunt about. "This person has X condition" tells the NDIA very little. "This person cannot shower unassisted, cannot prepare a meal safely, and requires prompting to take medication, and these limitations are expected to be lifelong" tells them what they are required to assess.

• Reports from specialists, GPs, occupational therapists, psychologists or other treating professionals
• Statements about whether the impairment is likely to be permanent
• Concrete description of functional impact across daily activities
• Evidence of what has already been tried, and its result
• Recent documentation — older reports carry less weight

What happens next

Once the NDIA has what it needs, it works to a defined decision timeframe rather than an open-ended one, and it may come back asking for more information. If it does, responding promptly matters — the clock is generally tied to when the agency has a complete request.

If access is granted, the next step is planning: a conversation about your goals and needs that produces your first plan. That plan is where funding is decided, and preparing for it properly is worth as much effort as the access request was. Our guide on preparing for a plan review applies to a first planning meeting as much as to a later review.

If you are refused

A refusal is not the end, and a good proportion of decisions change on review. You can request an internal review, and the window for doing so is short — generally a matter of months from the decision — so the single most important thing is not to sit on it while gathering perfect evidence.

A review is strongest when it addresses the specific reason given. If the decision said the impairment was not established as permanent, more detail about daily impact will not help; what is needed is evidence about permanence. Read the reason carefully and answer that. If an internal review does not resolve it, there are further external avenues beyond the agency.

Getting help with the process

Local Area Coordinators and early childhood partners help with access at no cost to you, and for many people that is enough. Advocacy organisations also support people through access and review, particularly where a request has been refused.

Note the sequencing, because it confuses people: a support coordinator is funded *in* a plan, so coordination is not available to help you get access in the first place. Once you are in, Support Connection is the lightest level of help to turn a first plan into working supports.

What a plan actually gives you

It is worth knowing what is on the other side. An approved plan funds reasonable and necessary supports related to your disability — which in practice can mean anything from a few hours of daily living support a week to a full roster of care, therapy, equipment, transport or help finding somewhere to live.

It is not a cash payment and it does not cover everyday costs that everyone has, like rent, groceries or utilities. What it funds is the disability-related gap: the things you need because of your disability that another person would not.

The bottom line

Access turns on function, permanence and evidence — in that order of misunderstanding. If you are unsure whether to apply, the honest answer is that a well-evidenced request is worth making, and that the cost of not asking is usually higher than the cost of being refused once.

If you are somewhere in this process and it is not making sense, a free Meet & Greet is a conversation rather than a form. We are a provider, not the NDIA — but pointing people toward the right door costs nothing.
