How to apply for the NDIS: a first-timer’s guide

Finding out that you — or your child — might need the NDIS can feel like being handed a form in a language you don't speak. The good news: the path in is more straightforward than it looks, and it's the same basic journey for everyone. This guide walks through all of it in plain English, from working out whether you're eligible to what happens after you're approved.

Most people get help with this — you don't have to do it alone. The NDIA funds free local partners (Local Area Coordinators, and Early Childhood partners for young children) whose whole job is to help you apply. We'll point to them along the way.

Step 1: Are you (or your child) eligible?

There are three access rules. You need to meet all three.

• Age. You must be under 65 when you apply. The standard application path is for people aged 9 to 65. Children younger than 9 go through the early childhood approach instead (see the next section). If you join before you turn 65, you can keep your NDIS supports afterwards.
• Residency. You must live in Australia and be an Australian citizen, a permanent resident, or hold a Protected Special Category Visa.
• Disability or early intervention. Either you have a permanent and significant disability that substantially reduces your ability to do everyday things (move around, communicate, socialise, learn, manage self-care or self-management), or you have an early-intervention need — getting support now would reduce how much support you'll need later.

You don't have to judge the disability test yourself. That's what the evidence from your treating professionals is for (Step 2), and the NDIA makes the call. If you're not sure whether you'd qualify, it's still worth applying — or speaking to a Local Area Coordinator first.

If it’s for your child under 9: start here

If you're a parent who's just been told your child needs support, this is your path — and it's deliberately gentler than the adult process. Children younger than 9 with a developmental delay or disability are supported through the NDIS early childhood approach, run by local early childhood partners.

The single most reassuring thing to know: you do not need a diagnosis, a referral, or any paperwork to make first contact. You can call or email an early childhood partner, describe your child's age and what you've noticed, and they'll help from there. For children younger than 6, you don't need a formal diagnosis at all — evidence of significant developmental delay is enough. For children aged 6 to 9, a confirmed diagnosis is usually needed.

An early childhood partner can connect your child to some supports straight away (sometimes without a full NDIS plan), and, if your child needs longer-term help, they'll guide you through applying to the NDIS. If your child is 9 or older, you follow the standard Access Request process below instead.

Step 2: Gather your evidence (the part that makes or breaks it)

If there's one place applications go wrong, it's here. The NDIA decides on the strength of your evidence of disability, so it's worth getting right the first time.

Good evidence comes from the professionals who already treat you — your GP, paediatrician, specialist, or allied-health professionals (occupational therapist, speech pathologist, psychologist, physiotherapist). Between them, the evidence needs to show three things:

• What your disability is — the diagnosis or condition.
• That it's permanent — it's lifelong, or won't go away with treatment (for young children, that it's a significant developmental delay).
• How it affects your daily life — the practical impact on moving around, communicating, learning, socialising, and managing day-to-day tasks.

A Local Area Coordinator or early childhood partner can tell you exactly what evidence to collect before you apply, which saves the back-and-forth that slows applications down.

Step 3: Make the Access Request

Once your evidence is together, there are two ways to apply:

• Phone the NDIS on 1800 800 110 and make a verbal Access Request. They can take your details over the phone and tell you what to send in.
• Complete the Access Request Form (ARF) and submit it — through the NDIS, by mail to NDIA, GPO Box 700, Canberra ACT 2601, or in person at a local office. If you don't have the form, call the number above and they'll send it to you.

You don't have to do this yourself. A Local Area Coordinator (or, for young children, an early childhood partner) can help you complete and submit the application — this is a free service. And you don't have to be the person with disability to apply: a parent, guardian, or nominee can apply on someone's behalf.

Step 4: Your access decision — the 21-day rule

Once the NDIA has your Access Request and all your supporting evidence, it must tell you whether you're eligible within 21 days. Two things to know:

• The 21 days only starts once they have everything. If they write to ask for more information, the clock effectively pauses until you provide it — so responding quickly keeps things moving.
• You'll get the decision in writing. If you're found eligible (an "access decision"), you move straight on to planning. If not, you have review rights (see below) — a "no" is not the end of the road.

If you’re approved: your first NDIS plan

Being found eligible is the beginning, not the end. Next comes a planning conversation — a meeting (in person, by phone or video) where you talk through your goals and the support you need, and the NDIA builds your first plan and budget.

This meeting matters: what you say shapes the funding you get for the next 12 months or more. Walk in prepared. Two of our guides cover exactly this:

• How to prepare for your NDIS planning meeting — what to bring, what to say, and how to talk about your goals.
• NDIS funding categories explained — how Core, Capacity Building and Capital funding work, so your plan makes sense when you get it.

If you’re not approved: you can ask for a review (don’t give up)

Plenty of people are knocked back the first time and get in on review — very often because the first application simply didn't include enough evidence of functional impact, which is fixable. There are two stages:

• Internal review. You can ask the NDIA to review its own decision. Request it within 3 months of getting the decision in writing; the NDIA aims to complete internal reviews within 60 days. This is your chance to add stronger evidence.
• External review. If you're still not happy, you can take it to the Administrative Review Tribunal (ART) — the independent tribunal that replaced the former AAT in October 2024. You have 28 days from the internal review decision to apply. Free advocacy services can help you through this.

If a review feels daunting, that's normal — and you don't have to do it alone. Disability advocacy organisations offer free, independent help with NDIS appeals.

A note on timing: the NDIS is changing

The NDIS is going through its biggest reforms since it began — foundational supports, changes to how children are supported, and a move toward needs-based assessments are all in progress. The access process described here is the current one (reviewed May 2026), but some steps may change over the next year or two. We track the changes that affect participants in our NDIS updates section — worth a look if you want to know what's coming.

Once you have a plan: finding the right providers

With a plan in hand, the last step is choosing who actually delivers your supports. This is where ProviderScout comes in — and it's free for participants, always.

• Start with choosing your first NDIS provider — a practical framework, the red flags to walk away from, and the service-agreement clauses worth checking.
• Decide how your plan is managed — our plan management guide compares self-managed, plan-managed and agency-managed.
• When you're ready, search and compare NDIS providers across Australia by service and suburb.

How to verify this information

The NDIS access process is set out on the official sites, and some details are changing through the current reforms — always confirm the current steps before you rely on them:

• How to apply and the Access Request Form on ndis.gov.au.
• Providing evidence of your disability — what counts as good evidence.
• The early childhood approach for children younger than 9.
• Requesting an internal review, and external review at the Administrative Review Tribunal.
