How to Apply for the NDIS — The Access Request Process, Step by Step

Applying for the NDIS starts with something called an Access Request — a form, plus evidence from a treating health professional, that the National Disability Insurance Agency (NDIA) uses to decide whether someone is eligible. It can feel bureaucratic and a little daunting the first time. This guide walks through exactly what's involved: who qualifies, what evidence you need, how to submit it, and what happens next.

Who's eligible — the two pathways

Before anything else, three basic requirements apply to everyone. You must be:

• Aged 0 to 64 when you apply — people 65 and over generally access support through My Aged Care instead
• Living in Australia, and either an Australian citizen, a permanent resident, or a Protected Special Category visa holder
• Assessed against one of two further pathways — see below

On top of age and residency, you need to meet either of these two sets of requirements:

1. Disability requirements

This is the main pathway for most adult participants. It applies if you have a disability related to a permanent impairment (or a psychosocial disability caused by a permanent impairment) that will significantly affect your life and your ability to do everyday tasks, and where you'll likely need NDIS supports for your lifetime.

2. Early intervention requirements

This pathway applies if you have an impairment (or psychosocial disability caused by an impairment) that is likely to be permanent — or you're a child younger than 6 with developmental delay — and where getting support now would reduce how much support you need in future, improve your ability to function, or stop things from getting worse.

You only need to meet one of these two pathways, not both. If you're not sure which applies, that's normal — it's part of what the assessment process is there to work out.

The evidence you need — and how to get it

This is the part families most often get stuck on, and it's also the part where a GP or treating specialist becomes genuinely useful. The NDIA wants "recent" evidence from a treating health professional relevant to your primary disability — a GP, paediatrician, orthopaedic surgeon, neurologist, or psychiatrist are all listed as examples.

Good evidence addresses:

• The disability and impairment itself — the diagnosis and its nature
• How it affects daily life — the tasks you need support to complete, and what kind of assistance you need
• Previous treatments and their outcomes — what's been tried and how it went
• Future treatment options — including, for the disability pathway, whether the condition is unlikely to improve with any known, evidence-based medical treatment

Practically, this usually means booking a longer appointment with your regular GP or specialist specifically to discuss the NDIS application — not squeezing it into the end of an unrelated visit. Bring a list of how the condition affects daily tasks (mobility, communication, social interaction, learning, self-care, self-management) so your treating professional has concrete detail to work with, rather than starting from a blank page. Letters, reports, and existing assessments from other treating professionals can be attached too — the NDIA builds a fuller picture from multiple sources where they exist.

The access request form

The access request form has two sections. Section 1 is completed by the applicant (or their parent, guardian, or legal representative) — personal details, consent, and information about the disability. Section 2 is completed by the treating health professional — their credentials, how long they've treated you, and the functional capacity evidence described above.

Three ways to submit it

Once the form and evidence are ready, there are three ways to get it to the NDIA:

• Online — through the NDIS service hub (myndisportal.ndis.gov.au)
• By mail — to NDIA, GPO Box 700, Canberra ACT 2601
• In person — at your local NDIS office

You can also get help from an NDIS partner in your local area, who can complete and submit the application on your behalf. And you're entitled to bring support to any meeting with the NDIA — a family member, friend, support coordinator, or recovery coach.

What happens in the 21 days

Once the NDIA has received your complete application — the form plus all supporting evidence — it aims to tell you whether you're eligible within 21 days. That's the target once everything is in; if evidence is missing or incomplete, the timeframe effectively resets once it's supplied, so a well-prepared application genuinely moves faster.

If you're found eligible, you become an NDIS participant and move on to planning — working out what supports your plan will fund. (We cover that step in a separate guide on the first planning meeting.)

If your access request is declined

If the NDIA decides you're not eligible, you'll receive a letter explaining the decision and the reasons behind it. From there, you have options:

• Request an internal review — you have 3 months from the day you receive the decision to ask for this. A different NDIA staff member than the one who made the original decision will review it.
• Apply to the Administrative Review Tribunal — if you still disagree after the internal review, you can request an external review within 28 days of that internal review decision.
• Reapply later — there's no limit on how many times you can submit a new access request, for example if your condition changes or new evidence becomes available.

A decline is not necessarily the end of the road, and it's genuinely common for circumstances, evidence, or the way an application is framed to change the outcome. We've written a separate, more detailed guide to the review and appeals process if this applies to your family.

What to do this week

None of this needs to happen in one sitting. Getting the evidence right the first time matters far more than getting it in fast.
