What Disabilities Does the NDIS Cover? A Plain-English Guide
The NDIS covers permanent disabilities that significantly affect how a person functions day to day. Not every health condition qualifies, but the list is broader than most people expect.
Understanding what counts can mean the difference between getting funded support and navigating the system alone.
What Makes a Disability Eligible for the NDIS?
The NDIS does not fund diagnoses. It funds functional impairment. That distinction matters more than most people realise when they first apply.
To be eligible, your disability must be permanent, or likely to be permanent, and it must substantially reduce your ability to participate in everyday activities. The cause can be neurological, cognitive, sensory, physical, or psychosocial.
You also need to be under 65 when you first apply, be an Australian citizen or permanent resident, and live in Australia.
One of my clients came to me after being knocked back on her first application. She has fibromyalgia. The rejection wasn't because fibromyalgia can't qualify. It was because her supporting evidence focused on her diagnosis rather than showing how it limits her ability to do things like cook, move around, or work. When she reapplied with functional evidence, she was approved.
The condition didn't change. The framing did.
What Are the 13 Disability Categories the NDIS Uses?
The NDIS groups eligible disabilities into 13 support categories. These are not funding categories. They're ways of classifying the nature of the impairment to assess what supports a person needs.
- Autism spectrum disorder
- Intellectual disability
- Physical disability
- Acquired brain injury
- Neurological disability
- Sensory disability (vision or hearing)
- Speech and language impairment
- Psychosocial disability (arising from a mental health condition)
- Developmental delay (for children under 6)
- Spinal cord injury
- Cerebral palsy
- Multiple sclerosis
- Down syndrome and other chromosomal conditions
These categories are a guide, not a strict checklist. A person with a traumatic brain injury might have impairments that touch on physical, neurological, and cognitive categories all at once.
What Is the Most Common Disability on the NDIS?
Autism spectrum disorder is the most common disability supported by the NDIS. Around 34 percent of all NDIS participants are autistic. That makes it by far the largest single group in the scheme.
Intellectual disability is second, followed by psychosocial disability, which covers mental health conditions severe enough to cause permanent functional impairment.
This matters because it shapes how services are designed and funded. If you have autism or an intellectual disability, there's a well-established path into the scheme with strong precedent for what supports get approved.
What About Mental Health Conditions?
Mental health is one of the most misunderstood areas of NDIS eligibility. Many people assume the NDIS doesn't cover mental health at all. That's wrong.
The NDIS covers psychosocial disability. That's a mental health condition that's severe, persistent, and causes significant functional impairment. Conditions like schizophrenia, bipolar disorder, severe depression, and borderline personality disorder can all qualify under this category.
What the NDIS doesn't fund is ongoing clinical treatment for mental illness. Medicare and the mental health system handle that. The NDIS steps in to fund the supports that help a person with a mental health condition live more independently, build daily living skills, and participate in the community.
I know this because one of my clients has schizoaffective disorder. He spent years thinking he wouldn't qualify because he was already seeing a psychiatrist. When we looked at how his condition affected his ability to leave the house, manage routines, and exercise consistently, the functional picture told a completely different story. He now has NDIS funding that includes capacity building, and strength training is part of his plan.
What Are the 21 Disabilities Listed Under the NDIS?
The NDIS also maintains a list of conditions it considers permanent by definition. These are sometimes called the List of Permanent Conditions or the 21 conditions list. If your diagnosis appears on it, you don't need to prove permanence separately.
That list includes:
- Autism spectrum disorder
- Cerebral palsy
- Down syndrome
- Hearing loss present at birth or before language development
- Huntington's disease
- Intellectual disability
- Multiple sclerosis
- Muscular dystrophy
- Prader-Willi syndrome
- Rett syndrome
- Spinal muscular atrophy
- Tourette syndrome
- Tuberous sclerosis
- Williams syndrome
- Acquired brain injury
- Spinal cord injury
- Blindness
- Deafblindness
- Severe chronic conditions of the brain, such as epilepsy with significant impairment
- Permanent physical disability from conditions like stroke
- Psychosocial disability from severe and persistent mental illness
If your condition isn't on this list, you're not necessarily ineligible. It means you need stronger functional evidence in your application. Many people qualify through functional impairment assessment even when their diagnosis isn't on the permanent conditions list.
What Conditions Are Commonly Approved That People Don't Expect?
This is where a lot of people miss out on support they're actually entitled to.
Traumatic brain injury is a good example. A person can look and sound completely fine in a conversation but have significant deficits in memory, planning, fatigue management, and impulse control. Because the impairment is invisible, many people don't realise they qualify. When we assess function rather than appearance, the picture changes fast.
Hearing loss is another. Significant hearing loss, especially when it affects communication and safety, is a recognised NDIS disability. Assistive technology, communication supports, and capacity building are all fundable.
Cerebral palsy covers a wide spectrum. Some people with cerebral palsy have mild motor impairment and still qualify because of how that impairment affects their daily function and participation. The severity of the diagnosis matters less than the impact on functioning.
I had a client with mild cerebral palsy who'd never considered applying for the NDIS because she thought she wasn't disabled enough. Her physio suggested it. Once she applied and was approved, her plan included exercise physiology and a personal trainer to build strength and address the specific movement patterns her condition creates.
It changed her quality of life in ways she hadn't thought possible before.
What the NDIS Does Not Cover
Knowing what's excluded saves time and frustration.
The NDIS doesn't cover age-related decline. If your impairment is primarily caused by ageing, you're directed toward aged care services instead.
It doesn't cover temporary conditions. A broken leg, a short-term illness, or a condition that's expected to resolve doesn't qualify. The impairment needs to be permanent or likely permanent.
It doesn't fund general healthcare, GP visits, hospital care, or clinical mental health treatment. Those sit within the health system.
It also doesn't cover conditions that create work-related incapacity without affecting everyday functioning. Income support for that falls under a different system.
How Exercise and Physical Support Fits Into NDIS Plans
This is something most NDIS guides skip over entirely.
For many participants, physical activity and exercise support are directly fundable through the NDIS. An NDIS personal trainer who understands disability, movement, and functional goals can be funded under Capacity Building or Core Supports depending on the participant's plan and goals.
This applies across a wide range of the disabilities listed above. Someone with multiple sclerosis managing fatigue and muscle weakness. Someone with autism building body awareness and regulation. A person with an acquired brain injury working on balance, coordination, and endurance. A participant with a psychosocial disability using structured exercise to support mental health and daily routine.
Physical support is one of the most underused parts of NDIS plans. Participants often don't know it's available, or they assume it only applies to people with severe physical disabilities. That assumption costs people real progress.
When I work with NDIS participants, the goal is always functional. We're not training for aesthetics. We're training so a person can transfer from a wheelchair more easily, manage fatigue better, get off the floor independently, or simply feel strong enough to engage with their life.
Those are measurable, fundable outcomes.
Frequently Asked Questions
Can I apply for the NDIS if I have a mental illness?
Yes. If your mental illness is severe, persistent, and causes significant functional impairment, it qualifies as a psychosocial disability under the NDIS. The key is showing how the condition affects what you can do, not just what you've been diagnosed with.
Does ADHD qualify for the NDIS?
ADHD on its own often doesn't meet the threshold, but it can qualify when it's severe, permanent, and causes substantial functional limitation. Many children and adults with ADHD also have co-occurring conditions like autism or intellectual disability that strengthen an application.
Can I get NDIS funding for a personal trainer?
Yes, in many cases. An NDIS-registered personal trainer or exercise physiologist can be funded under Capacity Building supports when the goals are tied to your disability-related functional needs. Your plan needs to include relevant goals, and the provider needs to work within NDIS guidelines.
What if my condition isn't on any list?
Apply anyway with strong functional evidence. Many approved participants have conditions not specifically named on any NDIS list. What matters is how your impairment affects your daily functioning, and whether that impairment is permanent.
Is cerebral palsy always covered by the NDIS?
Cerebral palsy is on the list of conditions considered permanently disabling by definition. This means the permanence requirement is automatically met. You still need to show functional impairment and meet the age and residency requirements.
What happens if I am already over 65?
If you're 65 or older when you first apply, you're not eligible for the NDIS. Aged care services would be the relevant pathway. If you're already an NDIS participant when you turn 65, you can choose to remain in the NDIS or transition to aged care.
What to Do Next
If you think you or someone you support might qualify for the NDIS, start with functional evidence. Get reports from your GP, specialist, occupational therapist, or allied health providers that describe what you can't do, not just what condition you have.
Then contact the NDIS directly or use a local area coordinator to begin an access request. If you're knocked back, you can request a review. Many approvals come after an initial rejection.
Once you have a plan, look at every support category available to you, including physical and capacity building supports. That's where a lot of people leave real value on the table.
If you're in Melbourne and want to understand how exercise support can fit into your NDIS plan, Better Start's NDIS personal training team works specifically with participants across a range of disabilities to build functional strength and achieve goals tied directly to their plan.
