What Is the NDIS? A Plain English Guide for Australians, Families and Carers

I have a version of the same conversation more times than I can count.

Someone calls our team and the first thing they say is that they’ve heard we work with NDIS clients, and they have an NDIS plan, but they’re not entirely sure what it covers or whether what they need from us would be included. Sometimes they’ve had the plan for months and have barely used it. Sometimes they’re newly approved and have no idea where to start. Sometimes it’s a family member calling on behalf of a parent or sibling, trying to make sense of a system nobody has properly explained to them.

That gap between having an NDIS plan and understanding what to do with it is one of the most common and most fixable problems in the disability support space. It’s also one that costs people real access to care they’re entitled to and need.

So let me explain the NDIS in plain language, without the jargon, without the bureaucratic framing, and with the practical detail that actually helps people make decisions.

The National Disability Insurance Scheme, known as the NDIS, is the Australian Government’s funding scheme for people with permanent and significant disability. It provides individualised funding that eligible Australians can use to access supports and services that help them live their daily lives, pursue their goals, and participate in their community. As of June 2025, the NDIS supports 739,414 Australians. It’s administered by the National Disability Insurance Agency (NDIA) and is one of the most significant social policy reforms in Australia’s modern history. You can find foundational information directly on the NDIS website, but this article explains it in a way that’s actually useful for real people making real decisions.

NDIS at a Glance

What it is	Australia’s national scheme funding individualised supports for people with permanent, significant disability
Who’s eligible	Under 65 when applying, Australian citizen or permanent resident, permanent disability significantly affecting daily function
How many	739,414 Australians as at 30 June 2025
Three support types	Core Supports (daily assistance), Capacity Building (therapy and skills), Capital Supports (equipment and home modifications)
Plan management	NDIA managed, plan managed, or self managed
Allied health funded	Physio, OT, speech pathology, EP, dietetics, podiatry, chiropractic (via Other Professional) all fundable where reasonable and necessary

Key Takeaways

The NDIS provides individualised funding for Australians with permanent and significant disability. Funding is based on your specific goals and needs, not a one-size-fits-all package.
To be eligible you must be under 65 when you apply, be an Australian citizen or permanent resident, and have a permanent disability that significantly affects your daily life.
NDIS plans contain three types of funding: Core Supports, Capacity Building, and Capital Supports, each covering different kinds of assistance.
You can choose how your plan is managed: NDIA managed, plan managed, or self managed. The choice affects which providers you can use and how much flexibility you have.
Allied health services including physiotherapy, occupational therapy, speech pathology, exercise physiology, dietetics, podiatry, and chiropractic can all be funded through the NDIS where they are reasonable and necessary.
If you are not eligible for the NDIS or are over 65, other pathways exist including the Support at Home program and Medicare for some allied health services.

The NDIS Explained: What It Was Designed to Solve

Before the NDIS existed, disability support in Australia was a patchwork. Different states and territories funded different services. Some people received significant support. Others received almost nothing. Access depended heavily on where you lived, what disability you had, and whether you happened to know the right people or ask the right questions.

The system wasn’t fair, it wasn’t consistent, and it wasn’t designed around the people it was supposed to serve.

The NDIS was established in 2013 following years of advocacy from people with disability, their families, and disability organisations who argued that Australia needed a national, insurance-based approach to disability funding: one that recognised the long-term costs of living with disability and provided consistent, needs-based support regardless of where in Australia you lived.

The scheme is built on a simple idea. People with significant permanent disability have the right to the supports they need to live ordinary lives. Those supports should be determined by the person’s individual goals and circumstances, not by what a bureaucracy decides is appropriate for someone with a particular diagnosis. The NDIS is participant-centred, which means the person with disability has choice and control over how their funding is used and which providers they work with.

It’s also an insurance model. Rather than providing ad hoc support that varies year to year depending on government budget decisions, the NDIS is designed to think across a person’s lifetime. Early investment in the right supports can reduce the need for more intensive and expensive care later.

The NDIS isn’t a charity and it isn’t welfare in the traditional sense. It’s a funded entitlement for people who meet the eligibility criteria. Understanding that distinction matters because it changes how people approach the scheme: not with gratitude for whatever they’re given, but with the expectation of supports that genuinely meet their needs. The Healthdirect NDIS page provides a clear consumer-focused overview if you want more background.

Who Is Eligible for the NDIS?

The NDIS has three eligibility requirements. You must meet all three.

Age

You must be under 65 when you apply. If you turn 65 before your application is processed, you won’t be eligible. People who are already NDIS participants can continue to receive support after turning 65 if they choose to, but they can’t apply for the first time after reaching 65. Children can access the NDIS from birth. Children under nine with developmental delay or disability can access support through the early childhood approach.

Residency

You must be an Australian citizen, a permanent resident, or a Protected Special Category Visa holder living in Australia. Temporary residents don’t qualify.

Disability

This is the most substantive criterion. To meet the disability requirements, you must have a permanent impairment that substantially reduces your ability to carry out everyday activities. The NDIS assesses impairment rather than diagnosis, which means having a particular condition doesn’t automatically make you eligible. What matters is how that condition affects your functioning. Impairments can be intellectual, cognitive, neurological, sensory, physical, or psychiatric. The key tests are that the impairment is likely to be permanent, that it substantially affects your daily functioning, and that you’re likely to need NDIS supports for your lifetime.

Early intervention

There’s also an early intervention pathway, which applies when providing support early is likely to reduce the need for support later. This is most commonly applied to young children with developmental delay or disability. Full eligibility details are available on the NDIS eligibility page.

How to Apply for the NDIS

You apply by contacting the NDIA on 1800 800 110 or through your local NDIS partner organisation. You’ll need to provide supporting evidence from your GP or treating health professional about your impairment and how it affects your daily life. The NDIA makes an access decision based on this evidence.

What supporting evidence to provide

A diagnosis report from your GP, specialist, or treating clinician confirming the nature of your impairment
Evidence that the impairment is permanent or likely to be permanent
Information about how the impairment affects your functional capacity in daily life: self-care, communication, mobility, learning, social participation
Functional reports from allied health professionals, particularly if the impairment is better understood through function than diagnosis alone

Occupational therapy functional capacity assessments are one of the most useful pieces of evidence for an NDIS application, because they directly document how disability affects daily living in concrete, measurable terms.

What happens after you apply

The NDIA will review your application and make an access decision. If you’re approved, you’ll enter the planning process where your goals and support needs are discussed and your plan is developed. If you’re not approved, you have the right to request a review of the decision.

How NDIS Plans Work

An NDIS plan is a document that outlines your goals and the funded supports allocated to help you achieve them. It’s not a fixed prescription. It’s a personalised resource you can use to access the services and supports that make sense for your situation.

Every plan includes a statement of goals and aspirations, a statement of participant supports outlining what the NDIS will fund, and the management arrangement for how funding is administered. Plans are reviewed regularly, typically annually, and can be reviewed earlier if your circumstances change significantly.

The planning meeting

The planning process involves a conversation with an NDIA planner or LAC (Local Area Coordinator) about your goals, your current supports, and what additional support you need. The quality of this conversation has a direct impact on the plan you receive. Coming prepared with a clear statement of your goals, a list of your current challenges in daily living, and any supporting reports from clinicians makes a significant difference to the outcome.

The Three NDIS Support Categories in Plain English

Core Supports

Core Supports fund the day-to-day assistance you need to live your life. This includes: Assistance with Daily Life (personal care, help with tasks at home), Assistance with Social, Economic and Community Participation (support to engage in community activities), Transport (funded transport assistance), and Consumables (low-cost disability-related items). Core Supports funding is generally flexible: unused amounts in one subcategory can often be used in another.

Capacity Building

Capacity Building Supports fund professional supports that help you build skills and increase independence over time. This is where allied health therapy sits: physiotherapy, occupational therapy, speech pathology, exercise physiology, dietetics, podiatry, and chiropractic are all fundable under Capacity Building: Improved Daily Living where they are reasonable and necessary. Capacity Building funding must be used within the specific subcategory it is allocated to. Our article on what Capacity Building NDIS funding can be used for explains the Improved Daily Living subcategory in detail.

Capital Supports

Capital Supports fund one-off or higher-cost items related to disability: assistive technology (equipment, communication devices, mobility aids), and home modifications (structural changes to improve accessibility). These are not therapy services but rather items and changes to the environment. An OT or other allied health professional is typically required to assess and justify capital supports before they can be approved.

The Three Types of NDIS Plan Management

NDIA managed

The NDIA pays registered providers directly on your behalf. This is the simplest option but limits you to using NDIS-registered providers only. Suitable for people who want straightforward administration without managing finances.

Plan managed

A registered plan manager handles payments to providers on your behalf. You can use both registered and some unregistered providers, giving you more choice. Plan management costs are covered by the NDIS as a separate budget line and don’t come out of your therapy or support funding. This is often the best option for people who want flexibility without taking on financial administration themselves.

Self managed

You handle all payments and reimbursements directly. You have the most flexibility in choosing providers, including those who are not registered with the NDIS. This option requires more time and administrative effort but gives you the greatest control.

What the NDIS Funds for Allied Health

Allied health is one of the most important and most commonly used areas of NDIS Capacity Building funding. Here’s how each discipline is funded.

Physiotherapy

Physiotherapy is funded under Capacity Building: Improved Daily Living (item code 15_055_0128_1_3) where the physiotherapy is directly related to the participant’s disability and supports their daily function or independence goals.

Occupational Therapy

OT is funded under Capacity Building: Improved Daily Living (item code 15_617_0128_1_3). OT also supports assistive technology assessments (funded under Capital Supports) and home modification reports. ADL assessment, Functional Capacity Assessments, and daily living skill building all fall within this funding.

Speech Pathology

Speech pathology is funded under Capacity Building: Improved Daily Living (item code 15_056_0128_1_3) for participants whose communication or swallowing difficulties are related to their disability.

Exercise Physiology

Exercise physiology is funded under Capacity Building: Improved Daily Living where structured exercise supports disability-related functional goals such as improving mobility, managing chronic pain related to disability, or building physical capacity for daily activities.

Dietetics

Dietetics is funded under Capacity Building: Improved Daily Living where nutritional management is directly related to the participant’s disability, including conditions such as neurological conditions and disabilities affecting eating and swallowing.

Podiatry

Podiatry is funded under Capacity Building: Improved Daily Living where foot health issues are related to the participant’s disability, including conditions such as diabetes-related foot complications and neurological conditions affecting foot function.

Chiropractic

Chiropractic is not a named service in the NDIS Pricing Arrangements but can be funded under the Other Professional item (15_056_0128_1_3) within Capacity Building: Improved Daily Living, where it’s deemed reasonable and necessary to support the participant’s disability-related goals. Clear documentation linking treatment to disability goals is essential.

What the NDIS Does Not Fund

Understanding what the NDIS doesn’t fund is as important as understanding what it does. This is one of the most common sources of frustration for participants and families.

Mainstream health services

The NDIS isn’t a substitute for the mainstream health system. Medical treatment, surgery, prescribed medications, GP consultations, and acute hospital care are the responsibility of Medicare and the public health system, not the NDIS. Physiotherapy for a broken leg in a person who doesn’t have a disability isn’t an NDIS matter, even if the person also has a disability.

Education

Educational supports for students with disability, including teacher aides and learning support within schools, are generally the responsibility of the education system. The NDIS may fund some therapy-based supports within school settings but doesn’t fund educational provision itself.

General health and wellbeing

The NDIS funds supports that are reasonable and necessary in relation to disability. It doesn’t fund gym memberships, general wellness programs, or health supports that any person might benefit from regardless of disability.

Day-to-day living costs

The NDIS doesn’t fund ordinary living expenses such as rent, food, clothing, or utility bills. The scheme funds the additional costs of living with disability, not the baseline costs everyone faces.

What to do when the NDIS isn’t the right pathway

If you’re over 65, or if the NDIS isn’t the right pathway for your situation, other options exist. Older Australians can access allied health including physiotherapy, occupational therapy, speech pathology, and dietetics through the Support at Home program, which commenced on 1 November 2025 and replaced Home Care Packages. For some allied health services, a Medicare Chronic Disease Management plan from your GP may also provide rebated access.

NDIS Plan Reviews

A plan review is the process through which your NDIS plan is assessed, updated, and renewed. Understanding how reviews work helps you make sure your plan reflects your actual needs.

Scheduled reviews

Most NDIS plans are reviewed annually. In the lead-up to your plan review, the NDIA will contact you to initiate the process. You’ll have the opportunity to discuss what has and hasn’t worked in your current plan, what your goals are for the next period, and whether any circumstances have changed.

Unscheduled reviews

You can request a plan review at any time if your situation changes significantly: if your disability has progressed, if you’ve moved, if a support you’ve relied on is no longer available, or if your current plan isn’t meeting your needs. Providing clear evidence of the change and its impact on your functioning is essential.

How allied health reports support plan reviews

Allied health reports are one of the most powerful tools for securing appropriate funding at a plan review. A well-written physiotherapy or occupational therapy report that documents your current functional level, the impact of your disability on daily activities, what therapy has achieved, and what further therapy would achieve gives the NDIA the evidence it needs to justify ongoing or increased funding.

If you’re approaching a plan review and feel your current funding doesn’t meet your needs, one of the most useful things you can do is ask your treating allied health professionals to prepare updated reports. Fleet Healthcare can provide these reports as part of ongoing clinical management.

How to Get the Most from an NDIS Plan

Having an NDIS plan is one thing. Using it effectively is another. I’ve worked with a lot of people who have had plan funding sitting untouched because they didn’t know they could use it for something specific, or because they were waiting until they felt organised enough to start.

The most useful advice I can give: start using your plan. If you have Capacity Building funding and you’re not currently accessing allied health therapy that would help you, reach out to a provider and book an assessment. The funding doesn’t accumulate if you don’t use it. It’s tied to the plan period and if you don’t use it, it’s effectively lost.

Work with a support coordinator

A support coordinator is an NDIS-funded role that helps you understand your plan, connect with the right providers, and navigate the system. Not every participant has a support coordinator, but those who do tend to get better outcomes from their plans. If you have Capacity Building: Support Coordination in your plan, use it.

Choose providers based on quality and fit

The NDIS gives you the right to choose your providers. Use that right. Ask about clinical experience, approach, and how the clinician will work with your specific disability. Ask whether they have experience with your condition. Ask whether they provide mobile services if getting to a clinic is a challenge.

Understand reasonable and necessary in your context

The more clearly you can articulate how a support is reasonable and necessary in relation to your specific disability and goals, the better positioned you are to access it. Your support coordinator, your allied health team, and the NDIS website are all resources that can help with this.

Common Misunderstandings

Myth	Reality
The NDIS funds everything related to disability	The NDIS funds supports that are reasonable and necessary in relation to a participant’s disability goals. It doesn’t fund mainstream health services, education, or general living costs. The distinction between disability-related and general health costs is important.
You need to have a specific diagnosis to qualify	The NDIS assesses impairment and functional impact, not diagnosis. A condition that affects daily functioning may qualify even without a well-known diagnostic label, while a named condition with minimal functional impact may not.
Once you have a plan, you’re stuck with it until review	You can request an unscheduled plan review at any time if your circumstances change significantly. You’re not required to wait for the annual review if your plan isn’t meeting your needs.
Self management is too complicated for most people	Self management requires more administrative effort but gives you the most flexibility in choosing providers. Many participants successfully self-manage with the help of financial management apps and clear record keeping.
You have to use registered providers	Only NDIA-managed plans require registered providers. Plan-managed and self-managed participants can use both registered and unregistered providers, significantly expanding their choice.

Frequently Asked Questions

What does NDIS stand for and what does it do?

NDIS stands for National Disability Insurance Scheme. It’s the Australian Government’s scheme for funding individualised supports for people with permanent and significant disability. It provides eligible participants with a plan that includes funding they can use to access services and supports that help them pursue their goals and live their daily lives. It’s administered by the National Disability Insurance Agency (NDIA) and currently supports 739,414 Australians as at June 2025.

Who is eligible for the NDIS in Australia?

To be eligible you must be under 65 when you apply, be an Australian citizen or permanent resident living in Australia, and have a permanent disability that significantly affects your daily functioning. The NDIS assesses impairment rather than diagnosis. Full eligibility criteria are available on the NDIS eligibility page.

How do I apply for the NDIS?

You apply by contacting the NDIA on 1800 800 110 or through your local NDIS partner. You’ll need to provide supporting evidence from your GP or treating health professional about your impairment and how it affects your daily life. The NDIA makes an access decision based on this evidence.

What is the difference between Core Supports and Capacity Building?

Core Supports fund the day-to-day assistance you need to live your life, such as personal care, community access, and transport. Capacity Building Supports fund professional supports that help you build skills and increase independence over time, such as physiotherapy, occupational therapy, speech pathology, and psychology. Core Supports funding is generally more flexible. Capacity Building funding must be used within the specific subcategory it’s allocated to.

What is plan management and which type is right for me?

Plan management refers to how your NDIS funding is administered. NDIA management means the NDIA pays providers directly but limits you to registered providers. Plan management uses a registered plan manager to handle payments and gives you access to both registered and unregistered providers at no extra cost. Self management means you handle payments directly and have the most flexibility but also the most administrative responsibility.

What allied health services can the NDIS fund?

The NDIS can fund physiotherapy, occupational therapy, speech pathology, exercise physiology, dietetics, podiatry, and chiropractic (via the Other Professional pathway) under Capacity Building: Improved Daily Living, where these services are reasonable and necessary and directly related to the participant’s disability. Assistive technology and home modifications are fundable under Capital Supports where justified by an allied health assessment.

Can I use my NDIS plan for physiotherapy or OT at home?

Yes. Mobile allied health services, where the therapist comes to your home, are fundable under the NDIS in the same way as clinic-based services. Fleet Healthcare provides mobile physiotherapy, occupational therapy, speech pathology, exercise physiology, and other allied health services across Sydney. Visit our services page to learn more.

What happens if I’m over 65 and can’t apply for the NDIS?

If you’re over 65, the Support at Home program, which commenced on 1 November 2025, is the primary pathway for older Australians to access allied health and other supports. Registration starts at My Aged Care or by calling 1800 200 422. Medicare Chronic Disease Management plans may also provide access to some allied health services.

How do I get a plan review if my current plan isn’t meeting my needs?

Contact the NDIA on 1800 800 110 and request an unscheduled plan review, providing evidence of how your circumstances have changed or how your current plan is failing to meet your needs. Allied health reports documenting your current functional level and what additional therapy would achieve are particularly helpful. Your support coordinator can assist with this process if you have one.

Can the NDIS fund support if I have a mental health condition?

Yes. Psychosocial disability arising from mental health conditions can qualify for NDIS support. The key is demonstrating that the condition is permanent or likely to be permanent, and that it significantly affects daily functioning. OT, psychology, and other allied health supports can be funded where they address the functional impacts of psychosocial disability and support the participant’s daily living goals.

The NDIS is one of the most significant things that has happened in Australian disability policy in a generation. For people who access it well, it provides genuine choice, genuine control, and genuine access to supports that can change the quality of daily life in real and lasting ways.

But accessing it well is the hard part. The gap between being an NDIS participant and actually getting the right supports is real, and it’s most often closed by people who understand how the scheme works, who advocate clearly for their needs, and who have the right allied health and coordination team around them.

If you’ve been sitting on an NDIS plan that you haven’t fully used, or if you’re not sure whether your plan includes the right supports for where you are now, the most useful thing you can do is have a conversation with a provider who has experience in your specific condition and can advise on what’s available to you.

That’s exactly the kind of conversation Fleet Healthcare has every day.

Fleet Healthcare provides mobile allied health services across Sydney for NDIS participants, including physiotherapy, occupational therapy, speech pathology, exercise physiology, dietetics, and therapy assistance. Visit our services page to learn more, or book a consultation today. We come to you, and we know how to work within your NDIS plan.
