Private Health Insurance vs NDIS vs Aged Care: Key Points
- Each system has a defined remit. Private health insurance covers medical treatment and some allied health. NDIS covers disability-related daily living supports for people under 65. Aged care covers support for Australians aged 65 and over (or 50 and over for First Nations Australians).
- The systems are designed to be complementary, not duplicative. NDIS funding cannot cover what private health insurance is reasonably expected to cover for the same service.
- Medicare sits underneath all three as the baseline for health treatment. It is separate from all three funding systems but interacts with each.
- Significant changes took effect from July 2025, restricting NDIS access for people under 65 in residential aged care.
- Coverage gaps exist. Understanding where each system ends helps you identify when you may need to look elsewhere.
Why This Question Matters
For many Australians living with disability or managing the care of an ageing family member, multiple funding systems are in play simultaneously. A person might have private health insurance, receive NDIS funding, and also be approaching the age threshold for aged care. Or a family might be trying to work out whether a particular therapy should be claimed through insurance, the NDIS, or a Medicare plan.
Getting this wrong wastes funding, causes delays, and sometimes results in people going without supports they are entitled to. Getting it right means each system is used for what it is designed for, with no unnecessary duplication and no avoidable gaps.
This guide sets out what each system covers, where the boundaries lie, and how they interact.
The Four Systems: A Starting Framework
Before comparing them, it helps to understand the purpose each system is built around.
| System | Purpose | Who it covers | Means tested? |
|---|---|---|---|
| Medicare | Acute medical treatment | All Australian residents | No |
| Private health insurance | Medical and some allied health treatment | Policyholders | No (premiums vary) |
| NDIS | Disability-related daily living supports | Australians under 65 with permanent disability | No |
| Aged care (Support at Home / residential) | Support for older Australians | Aged 65+ (or 50+ for First Nations) | Yes |
Medicare is the foundation. The other three systems operate on top of it, each covering different categories of need.
What Medicare Covers
Medicare is not directly part of the private health insurance, NDIS, or aged care comparison, but it underpins all three.
Medicare funds:
- GP consultations (with a Medicare rebate).
- Specialist consultations when referred by a GP.
- Diagnostic imaging and pathology.
- Public hospital treatment as a public patient.
- Limited allied health sessions through Chronic Disease Management Plans (up to 5 allied health visits per calendar year) and Mental Health Treatment Plans (up to 20 psychological therapy sessions per year).
- Some dental services for children under the Child Dental Benefits Schedule.
Medicare does not fund:
- Ongoing disability supports.
- Aged care services.
- Most dental treatment for adults.
- Most optical, physiotherapy, or other allied health outside the specific plans above.
- Private hospital accommodation or theatre fees (this is where private health insurance applies).
What Private Health Insurance Covers
Private health insurance in Australia has two main components: hospital cover and extras (ancillary) cover.
Hospital cover
Hospital cover funds private hospital admissions, including accommodation, theatre fees, and specialist fees (subject to gap payments). It applies when you choose to be treated as a private patient in a private or public hospital.
Hospital cover does not fund:
- Outpatient services or community-based treatments.
- Disability supports at home.
- Aged care services.
- Ongoing therapy or allied health outside a hospital stay.
Extras cover
Extras cover funds a defined annual limit of allied health services. What is covered depends on your specific policy, but typically includes:
- Physiotherapy.
- Occupational therapy.
- Speech pathology.
- Psychology (some policies).
- Dietetics.
- Chiropractic and podiatry.
- Dental and optical.
The key limitation is the annual benefit limit. Most extras policies cover a specific dollar amount per service category per year (for example, $500 per year for physiotherapy). Once that limit is exhausted, you pay the remainder out of pocket.
Private health insurance does not cover:
- Personal care or domestic assistance.
- Home modifications or assistive technology.
- Support coordination or plan management.
- Transport to appointments.
- Community participation supports.
- Residential aged care fees.
These are the types of supports funded by NDIS or aged care, not private health insurance.
What the NDIS Covers
The NDIS funds reasonable and necessary supports for Australians under 65 who have a permanent and significant disability. The funding is non-means-tested.
NDIS core supports include:
- Assistance with daily life (personal care, domestic assistance, meal preparation).
- Transport.
- Consumables (continence products, low-cost assistive technology).
- Community participation.
NDIS capacity building supports include:
- Support coordination.
- Improved living arrangements.
- Increased social and community participation.
- Finding and keeping a job.
- Improved health and wellbeing.
- Improved learning.
- Improved daily activity (including allied health such as occupational therapy, physiotherapy, speech pathology, and psychology for disability-related goals).
NDIS capital supports include:
- Assistive technology.
- Home modifications.
- Specialist disability accommodation (SDA).
What the NDIS does not cover
The NDIS has a clear principle: it does not fund supports that are the responsibility of other systems. Specifically, NDIS funding cannot be used for:
- Medical treatment that is the responsibility of the health system (Medicare or private health insurance).
- Supports that are universally available to the general public.
- Aged care services for people who are eligible for aged care.
- Costs that a private health insurer is reasonably expected to cover.
This last point is critical. If your private health insurance policy covers physiotherapy, you cannot use NDIS funding as a substitute or to avoid using your insurance. You should claim from your insurance first, and NDIS may cover the gap or additional sessions beyond your insurance limit, where the NDIS has approved those sessions as reasonable and necessary for your disability goals.
The age boundary
NDIS eligibility ends at 65. People who have not entered the NDIS before their 65th birthday cannot apply. People who are receiving NDIS supports when they turn 65 can continue them indefinitely and do not transfer to the aged care system automatically. However, they cannot receive new aged care program funding for the same supports.
What Aged Care Covers
The aged care system covers Australians aged 65 and over (50 and over for First Nations Australians, and some other eligibility exceptions). The main programs are:
Support at Home (from November 2025)
The Support at Home program replaced Home Care Packages from 1 November 2025. It provides funding for older Australians to remain living at home with funded supports. Classification levels 1 to 8 determine the annual budget, with higher levels receiving larger budgets for more complex needs.
Support at Home funds:
- Personal care and hygiene.
- Domestic assistance.
- Nursing and clinical care.
- Allied health and therapy.
- Transport.
- Assistive technology and home modifications.
- Social support and community activities.
- Palliative care (including the End-of-Life Pathway).
Residential aged care
Residential aged care funds accommodation and care for older Australians whose needs cannot be safely met at home. It is means-tested, with fees depending on income and assets.
What aged care does not cover
- Acute medical treatment (this remains Medicare and private health).
- Dental treatment (with limited exceptions).
- Costs the person chooses to incur but which are not assessed as care needs.
- Private goods and lifestyle expenses beyond basic comfort.
How the Systems Interact: Common Scenarios
Scenario 1: NDIS participant with private health insurance needing physiotherapy
A 32-year-old NDIS participant with cerebral palsy has private health extras cover that includes physiotherapy to $600 per year. Their NDIS plan includes funding for physiotherapy as a capacity building support.
How this works: The participant should use their private health insurance extras cover for physiotherapy first. Once the $600 annual limit is exhausted, NDIS funding can cover additional sessions, up to the amount approved in the plan. They cannot use NDIS funding for sessions that are within their insurance limit.
Scenario 2: Person turning 65 with an NDIS plan
A 64-year-old NDIS participant approaches their 65th birthday. Their plan covers personal care, support coordination, and assistive technology.
How this works: Their existing NDIS supports continue after they turn 65. The NDIS does not automatically transfer them to aged care. However, they cannot apply for new aged care program supports for the same areas their NDIS plan covers. If their needs change significantly after 65, the NDIS can reassess and adjust their plan.
Scenario 3: Older Australian with private health insurance and Support at Home funding
A 74-year-old has a Support at Home classification and also holds private health insurance with extras cover.
How this works: Their private health extras cover applies to allied health services they receive as outpatients (physiotherapy, speech pathology). Their Support at Home funding covers personal care, domestic assistance, and other daily living supports. The two systems can operate alongside each other, covering different service categories.
Scenario 4: Hospital discharge requiring ongoing therapy
A 55-year-old with an acquired brain injury is discharged from hospital after a private hospital stay funded by their health insurance. They now need ongoing occupational therapy and home modifications.
How this works: The private hospital stay was covered by insurance. Ongoing post-discharge therapy may be covered partly by Medicare (Chronic Disease Management Plan), partly by NDIS (if the person meets NDIS eligibility and the therapy relates to disability goals), and partly by private health extras. Home modifications are an NDIS capital support if the person is NDIS-eligible. The interaction between these systems requires coordination, often through a support coordinator or social worker.
Coverage Gaps: When Nothing Pays
Gaps in coverage are a documented problem in the Australian care system. Common situations where no system covers a need include:
- Dental care for adults: Medicare does not cover most adult dental, private health extras cover has low annual limits, NDIS does not cover general dental, and aged care does not routinely cover dental. Out-of-pocket costs for dental are common across all groups.
- Mental health beyond session limits: Medicare funds up to 20 psychological therapy sessions per year. NDIS funds psychology for disability-related goals. Private health covers psychology up to annual limits. People with complex mental health needs may exhaust all three before their needs are met.
- Supports for people aged 50-64 with age-related decline who do not have a permanent disability: These people are not yet eligible for aged care (which starts at 65) and may not meet NDIS eligibility if their condition is not assessed as a permanent and significant disability.
- Carer supports: Informal carers have their own support gap. The Carer Gateway and carer payments through Centrelink exist, but formal funded support for carers is limited.
When you identify a gap, the following pathways are worth investigating: state and territory government disability or community services programs, Commonwealth Home Support Programme (CHSP, for people with lower-level needs), community service organisations, and Centrelink carer payments.

Frequently Asked Questions
Can I use private health insurance and NDIS funding at the same time? Yes, but not for the same service at the same time. You should claim from private health insurance first. NDIS funding can cover what insurance does not, or additional sessions beyond your insurance limit, where the NDIS has approved those supports.
Does private health insurance cover disability supports? Extras cover funds some allied health services up to annual limits. It does not cover personal care, home modifications, assistive technology, support coordination, or the ongoing daily living supports that the NDIS funds.
At what age does NDIS eligibility end? NDIS eligibility ends at 65. People already on the NDIS before turning 65 can continue their supports but cannot apply for new aged care program funding for the same supports.
What does Medicare cover that the others do not? Medicare covers GP and specialist consultations, diagnostic tests, and public hospital treatment as a public patient. It also covers a limited number of allied health sessions through Chronic Disease Management and Mental Health Treatment Plans.
Can a person under 65 in a nursing home access NDIS? Since changes introduced on 1 July 2025, people under 65 in residential aged care face strict eligibility restrictions. Most cannot access NDIS, with limited exceptions including First Nations Australians aged 50 and over experiencing homelessness.
What happens if no system covers what I need? Look at state and territory government programs, the Commonwealth Home Support Programme, carer payments through Centrelink, and community service organisations. A support coordinator or social worker can help identify options specific to your situation.
