NDIS vs My Aged Care: Whose Rules Apply, and When

One number decides which system you are in

Australia runs two separate systems for funding daily support, and the thing that sorts people between them is not how much help they need. It is how old they were on the day they first applied.

The NDIA states the rule plainly: anyone who applies for the NDIS must be younger than 65 on the day they apply. Eligibility runs from 0 to 64 years, alongside the residency and disability or early intervention requirements. At 65 and over you are not eligible to apply, and aged care supports are the pathway instead. Same person, same disability, same support needs, different system, purely because of the date on the form.

If you are already a participant when you turn 65

Turning 65 does not push you out. If you were already an NDIS participant, you get a choice: keep using NDIS supports, or change to aged care supports. The NDIA is explicit that nothing changes if you choose to continue as a participant.

There is one hard condition attached, and it is the sentence to remember. You cannot use NDIS supports and aged care supports at the same time. It is one system or the other, not a blend, and that rules out the arrangement plenty of families assume they can build.

There is also one event that removes the choice. If you move into residential aged care after turning 65, you have to leave the NDIS.

Why this is called a one-way door

Put the two rules together and you can see the trap. You cannot apply for the NDIS at 65 or over. So if you leave the NDIS after 65 to take up aged care supports, there is no route back in, because re-entry would require an application you are no longer eligible to make.

That is why the decision at 65 deserves proper thought rather than being handled as paperwork. It is not a service switch you can trial for six months and reverse. Anyone facing it should get independent advice before signing anything, and should ask directly what happens to each individual support they currently rely on, one by one, rather than accepting a general reassurance.

First Nations participants can choose from 50

This provision is real and widely unknown. The NDIA states that a First Nations person who is an NDIS participant can choose to access aged care supports from 50 years of age, or continue as an NDIS participant.

It is a choice rather than a cut-off. If it applies in your family, the same warning applies with more force, because the decision arrives fifteen years earlier and the one-way logic still holds once you are over 65.

What actually differs day to day

Beyond the age rule, the two systems behave differently in ways families feel quickly.

How supports get decided differs. The NDIS funds supports that are assessed as reasonable and necessary in relation to a participant's disability, and the plan is built around goals. Aged care assessment works from a different starting point, focused on function and care needs in later life rather than lifelong disability, and the assessment process is separate.

What gets funded differs in emphasis. The NDIS funds capacity building, meaning supports intended to increase a person's independence over time, alongside daily supports. Aged care is weighted more toward maintenance and care. For a 63 year old with cerebral palsy who is still building skills, that difference is not academic.

Cost structures differ too. Aged care programs generally involve assessment and can involve means-tested contributions toward the cost of care. The NDIS does not means test its funded supports, although participants pay their own everyday living costs such as rent, food and utilities in any setting.

What to do if you are in your late fifties or early sixties

Apply before 65 if there is any prospect of eligibility. This is the single most consequential piece of practical advice in this article. A person who applies at 64 and is found eligible keeps the choice for the rest of their life. A person who waits until 66 never had one. Eligibility is never guaranteed, and access decisions sit with the NDIA on the evidence, but an application not made cannot succeed.

Get the functional evidence assembled while the treating team knows the person well. Recent allied health reports age badly and are harder to reconstruct later.

Then get clear on what supports the household actually depends on, so that when the choice at 65 arrives you can compare like with like instead of comparing a brochure with a fear. Our explainer on what in-home support looks like day to day is a reasonable place to map that out, the practical detail for our own service sits on our in-home care in NSW page, and the wider system is unpacked without jargon on our NDIS help page.

We support people under both funding types and we are not going to pretend one is universally better. The point of this piece is narrower and more useful: know which door you are standing at, and know which way it turns.
