What Are the NDIS Access Criteria?

The NDIS access criteria outline the requirements a person must meet to become eligible for the National Disability Insurance Scheme (NDIS). These criteria are designed to ensure that individuals who require ongoing disability support can access the services and funding they need.

To qualify for NDIS support, applicants must meet three key NDIS access criteria set by the National Disability Insurance Agency (NDIA):

1. Age Requirements

You must be under 65 years of age at the time you apply for the NDIS. If you are already receiving NDIS support before turning 65, you may continue to receive services under the scheme.

2. Residency Requirements

Applicants must live in Australia and be one of the following:

Australian citizen
Permanent resident
Protected Special Category
Visa holder

These residency requirements ensure that NDIS funding supports people who are legally living in Australia.

3. Disability Requirements

To meet the NDIS disability access criteria, a person must have a permanent and significant disability that affects their ability to complete everyday activities independently.

This disability must substantially impact one or more areas of daily functioning, such as:

Communication
Social interaction
Learning
Mobility
Self-care
Self-management

Medical evidence and professional reports are typically required to demonstrate how the disability affects daily life.

Understanding the NDIS access criteria is the first step in determining whether you or a loved one may be eligible to apply for NDIS support.

Understanding NDIS Access: Criteria, Age, and Residency Requirements Explained

Q: What does substantial functional impairment mean under the NDIS access criteria?

Substantial functional impairment under the NDIS means a permanent disability significantly reduces a person's ability to perform everyday activities in one or more of six life domains including communication, social interaction, learning, mobility, self care and self management.

Q: How does the NDIA decide if my impairment is substantial?

The NDIA evaluates reports submitted with the access request. Health professionals must describe functional limitations, risks, and required supports.

Q: Can I apply for the NDIS if my condition fluctuates?

Yes. The NDIA assesses the overall impact of your condition over time and whether ongoing disability specific support is required.

Q: What is the most common reason NDIS access applications are rejected?

Most applications are rejected due to insufficient functional evidence describing how the disability impacts daily activities.

Q: What evidence do I need to demonstrate substantial functional impairment?

Evidence usually includes a medical diagnosis, occupational therapy functional assessment, and supporting allied health reports.

Q: Can I reapply if my NDIS access request is rejected?

Yes. Applicants can request an internal NDIA review and appeal to the Administrative Appeals Tribunal if required.

The National Disability Insurance Scheme (NDIS) can be difficult to navigate at times as one attempt to figure out some kind of secret code. You know that it is available but knowing how to get it may be the greatest challenge. The good news? The process is clearly defined, and once you understand the core NDIS eligibility criteria, the path forward becomes much clearer.

We have been assuring our clients a smooth ride at Care Au, a reputable provider of care in Melbourne, so your family can enjoy this ride too. This general guide will divide the three primary pillars of eligibility to NDIS support: Age, Residency, and Disability. We will also provide a NDIS eligibility checklist where you will be guaranteed to take the first step towards acquiring the life-changing support you deserve with confidence.

Understanding the NDIS Age Requirements

The NDIS is designed as a lifetime support system for people who acquire or live with a permanent disability. Because of this, strict NDIS age requirements are in place at the point of application.

The Under-65 Rule

The golden rule is this: You must be under 65 years old when you first apply to the NDIS.

Aged 9 to 64: If you are within this age range, you will apply directly to the National Disability Insurance Agency (NDIA) or be supported by a Local Area Coordinator (LAC).
Children Under 9: Children younger than nine years old, including those with developmental delay or disability, access the scheme through the Early Childhood Approach (ECA). This pathway is managed by an Early Childhood Partner (ECP) and is often referred to as early intervention. The focus here is to provide support as early as possible to improve long-term outcomes and reduce the need for support later in life.

What Happens If I’m Over 65?

If you are 65 or older and have never been an NDIS participant, you will be directed to alternative government support.

You will typically access support through My Aged Care. This includes aged care packages and other programs designed for older Australians.
A Crucial Exception: If you were already an NDIS participant before your 65th birthday, you generally have the choice to remain on the NDIS or transition to My Aged Care. The choice is yours.

NDIS Residency Requirements: Where You Need to Be

The second major requirement is about your connection to Australia. To meet the NDIS requirements for residency, you must satisfy two conditions:

You Must Live in Australia: You need to be currently residing in the country.
You Must Be One of the Following:

An Australian Citizen.
An Australian Permanent Resident.
A Protected Special Category Visa (SCV) Holder.

A Protected Special Category Visa (SCV) Holder. This requirement ensures the scheme is funded and utilised by those with a secure and ongoing connection to Australia. Unfortunately, temporary visa holders or visitors are not eligible under the current rules.

Meeting the NDIS Disability Requirements

This is often the most detailed part of the application, as it requires strong evidence. The NDIS is not for temporary conditions; it is for those with permanent and significant disability.

Defining Permanent and Significant Disability

To meet this criterion, your impairment must be both permanent and significant in its impact on your daily life.

1. The Impairment Must Be Permanent

A permanent impairment is one that is likely to be life-long, and all available and appropriate treatments have been attempted with no expected improvement. This impairment can be:

Physical
Intellectual
Cognitive
Neurological
Sensory
Psychosocial (mental health related)

2. The Impact Must Be Significant (Substantially Reduced Functional Capacity)

This is the key metric. The NDIA assesses how your permanent impairment affects your ability to participate in everyday activities across six main domains of life. Your functional capacity must be substantially reduced in one or more of these areas.

Life Domain	What it means for NDIS Access
Communication	Difficulties being understood or understanding others.
Social Interaction	Difficulties making and keeping friends or interacting in the community.
Learning	Difficulties acquiring new knowledge and skills.
Mobility	Difficulties moving around the home, community, or performing physical tasks.
Self-Care	Difficulties with personal tasks like showering, dressing, and eating.
Self-Management	Difficulties with problem-solving, planning, decision-making, or managing daily tasks.

You must also prove that you need disability-specific aid (either in the form of people or technology) to accomplish these tasks and that you are likely to need them over the course of your life.

The Importance of Medical Evidence

The NDIA will determine whether you are eligible or not by what you provide. The more vivid and graphic your evidence is, the higher the chances of a successful application. You must provide:

Diagnostic Reports: It is a formal document of a qualified professional (GPs, specialist, paediatricians or psychiatrists) certifying the diagnosis of the impairment and that the impairment is enduring.
Functional Assessments: The reports of allied health practitioners specifically stating the effects of the disability on your functional capacity in the six spheres of life. These reports need to be very clear about why your capacity is considerably diminished.

Hot Tip for Applicants: In compiling evidence, you should instead focus not on the diagnosis, but how disability affects your everyday life and how you require constant assistance.

Your NDIS Eligibility Checklist: Are You Ready to Apply?

Check your eligibility to submit your Access Request Forum (ARF) by using this brief-list of requirements:

Requirement	Yes / No
Age	Were you under 65 on the day you lodged your application?
Residency	Are you an Australian Citizen, Permanent Resident, or Protected SCV holder living in Australia?
Permanency	Do you have a permanent impairment (likely to be lifelong)?
Significance	Does your impairment substantially reduce your capacity in one or more of the six life domains (Communication, Mobility, Self-Care, etc.)?
Support Need	Do you require ongoing disability-specific supports from the NDIS? (Or, are you seeking early intervention to reduce future need?)

When you can answer these questions with certainty, yes, then you probably fit the qualifications to NDIS and are not to hesitate in applying.

NDIS Access Criteria – Frequently Asked Questions

What does “substantial functional impairment” mean under the NDIS access criteria?

NDIS access criteria substantial functional impairment means that your permanent disability significantly reduces your ability to perform everyday activities in one or more of six key life domains: Communication, Social Interaction, Learning, Mobility, Self-Care, and Self-Management. “Substantial” means more than occasional difficulty — it means you are unable to perform the activity safely or reliably without disability-specific support, assistive technology, or environmental modifications.

How does the NDIA decide if my impairment is substantial?

The NDIA relies entirely on the evidence submitted with your access request. Assessors review reports from health professionals describing what you can and cannot do, how long tasks take, risks involved, and what supports are required. Functional assessments from occupational therapists are often the strongest evidence.

Do I need to be impaired in multiple life domains to qualify?

No. You only need substantial functional impairment in at least one of the six life domains. However, evidence across multiple domains may lead to a broader NDIS support plan.

Can I apply for the NDIS if my condition fluctuates?

Yes. The NDIA assesses your overall functional capacity over time. If you require ongoing disability-specific support even during better periods, you may still meet the access criteria.

What is the most common reason NDIS access applications are rejected?

The most common reason is insufficient evidence describing functional limitations. Applications that only mention a diagnosis without explaining daily impacts often fail to meet the NDIS threshold.

What evidence do I need to demonstrate substantial functional impairment?

Strong evidence includes a confirmed diagnosis from a GP or specialist, a functional capacity assessment from an occupational therapist, and reports from allied health professionals describing daily support needs.

Can I re-apply if my NDIS access request is rejected?

Yes. You can request an internal NDIA review. If the decision remains unchanged, you can appeal through the Administrative Appeals Tribunal (AAT). Many applicants succeed once stronger evidence is submitted.

Does the NDIS cover children under 9 years old?

Yes. Children under nine access support through the Early Childhood Approach, which focuses on early intervention delivered by Early Childhood Partners.

How long does the NDIS access decision take?

The NDIA aims to make access decisions within 21 days after receiving all required information. If further evidence is requested, the process may take longer.
