What Is the NDIS? Eligibility Rules Explained

The National Disability Insurance Scheme, or NDIS, is an Australian scheme that can fund disability-related supports for eligible people. It is designed to help participants pursue goals, improve independence, and build capacity for everyday life.

The NDIS is not one provider or one service. It is a funding framework that can support approved participants to access different supports, providers, therapies, equipment, and services depending on the goals and supports included in their plan.

That distinction matters for searchers and families who are new to the system. When people ask what the NDIS is, they are often really asking two questions at once: what the scheme does, and whether they personally can access it.

Eligibility is decided by the NDIA. In broad terms, an access request usually looks at age, residency, and whether the person meets the disability or early intervention requirements.

A person may be eligible if they are under 65 when they make their first access request, live in Australia and meet residency requirements, and have a permanent disability that has a significant impact on their daily life.

The NDIA also has early intervention pathways in some cases. That means not every eligible person enters through exactly the same route, but the access rules still centre on how disability affects everyday functioning and support needs.

The age rule is generally about the age at first access, not whether a person will turn 65 later. If a participant enters the NDIS before they turn 65, that is different from trying to access the scheme for the first time after 65.

Residency requirements are also important. In practice, the NDIA looks at whether the person lives in Australia and meets the relevant residency criteria under the scheme rules.

These are often the easiest criteria to check first, because they are more straightforward than the disability-related evidence that follows.

Permanent generally means the disability is likely to be lifelong. Significant generally means it has a meaningful effect on functional capacity and the person's ability to take part in everyday activities without disability-related supports.

The NDIA does not simply look at a diagnosis in isolation. It also considers the real-life impact of disability on things like communication, mobility, self-care, self-management, learning, or social interaction.

This is one reason why two people with the same diagnosis may not have identical access outcomes or identical plans. Functional impact and evidence matter.

People often search this question because they know the NDIS exists, but they are unsure what information actually helps when applying. In many cases, the most useful evidence explains how disability affects daily life, not just what the diagnosis is called.

Reports from treating health professionals, assessments, letters, and other supporting documents can help explain functional impact, long-term needs, and why disability-related supports may be required.

The stronger the evidence about day-to-day impact, the easier it often becomes to understand the case for access.

If an access request is approved, the next step is usually planning. That is where goals, support needs, circumstances, and funding categories become more relevant.

This is also the point where many participants begin thinking about how to read their plan and how they want their funding to be managed. Those are separate questions from eligibility, which is why we cover them in separate guides.

If you are searching for what the NDIS is and who is eligible, the short answer is this: the NDIS is a disability support funding scheme, and eligibility is generally based on age, residency, and whether disability has a permanent and significant impact on daily life or requires early intervention supports.
