The National Disability Insurance Scheme (NDIS) is Australia's national program supporting people with permanent and significant disability, and applying involves meeting eligibility criteria, submitting an access request, and working through a planning process with the National Disability Insurance Agency (NDIA). Understanding each stage before you begin can help you prepare your evidence, manage your expectations, and engage with the right supports from the start.
What is the NDIS and who is it for?
The NDIS funds reasonable and necessary supports for Australians who have a permanent disability that significantly affects their ability to participate in everyday activities. It is administered by the NDIA and operates under the *National Disability Insurance Scheme Act 2013*. The scheme is designed to be individualised, meaning your plan is built around your specific goals and circumstances rather than a one-size-fits-all package.
To be considered, you must be an Australian citizen, a permanent resident, or hold a Protected Special Category Visa. You must also be aged under 65 when you first apply. The scheme covers a wide range of physical, intellectual, sensory, cognitive, and psychosocial disabilities, but not every condition automatically qualifies. What matters is the functional impact of your disability on daily life, not the diagnosis label alone.
If you are already receiving some disability supports through a state or territory government program, you may still be eligible for the NDIS, and the NDIA works with state and territory governments to manage this transition. More information is available directly at (NDIS.gov.au).
Eligibility criteria explained
The NDIA assesses eligibility based on several criteria, all of which must be met simultaneously. These are known as the access criteria, and they fall into two broad groups: age and residency requirements, and disability or early intervention requirements.
For the disability requirements, your condition must be attributable to a permanent impairment that is likely to be lifelong. The impairment must substantially reduce your functional capacity in at least one of the following areas: self-care, self-management, mobility, communication, learning, or social interaction. Alternatively, if the impairment is not permanent but early intervention could reduce its long-term impact, you may qualify under the early intervention pathway.
For children, the NDIA uses a developmental delay pathway, which allows younger children whose support needs are not yet fully defined to access the scheme. The NDIA publishes detailed information about how each criterion is assessed at (NDIS eligibility and access requirements).
It is worth noting that meeting the eligibility criteria does not mean any specific level of funding will be provided. Eligibility and planning are separate stages, and what you receive in your plan depends on a further assessment of your reasonable and necessary support needs.
How to submit an access request
The first formal step is submitting an access request to the NDIA. You can do this by calling the NDIA directly, by completing an Access Request Form and submitting it in writing, or by visiting a local NDIS office or an NDIS partner in the community, such as a Local Area Coordinator (LAC) or an Early Childhood Partner.
When you submit your access request, you will need to provide supporting evidence about your disability. This typically includes reports, assessments, or letters from treating health professionals such as your general practitioner, specialist, psychologist, or allied health provider. The strength and specificity of this evidence significantly affects how smoothly the access decision proceeds, so it is worth working with your treating team to ensure reports address functional impact rather than simply listing diagnoses.
If you are unsure where to begin, the NDIA website provides guides on what evidence is needed for different disability types at (NDIS.gov.au). You may also seek assistance from a disability advocacy organisation, which can help you prepare your request at no cost.
The planning process: what to expect
Once your access request is approved, you will be contacted to begin the planning process. This usually involves a planning conversation with an NDIA planner or your LAC. The goal of this conversation is to understand your current situation, your goals, and what supports you need to achieve those goals.
Before your planning conversation, it helps to think about your daily routine, what areas of life you find most challenging, what you would like to achieve in the short and long term, and what informal supports (such as family and friends) you already have. Writing these down in advance ensures nothing is overlooked during the meeting itself.
Your plan will include funded supports across relevant support categories. Depending on your circumstances, your plan may be self-managed, plan-managed, or NDIA-managed. Each option affects how you can engage with best NDIS providers in Sydney and other registered and unregistered providers across the country. Your planner or LAC can explain the differences and help you choose the approach that suits you best.
How long does the process take?
The NDIS does not publish a fixed processing guarantee for every application, and individual timelines vary considerably depending on your circumstances, the completeness of your evidence, and local demand. As a general guide, the NDIA aims to make access decisions and begin planning in a reasonable timeframe, but some applicants experience longer waits, particularly when additional information is requested.
To avoid unnecessary delays, submit complete, functional evidence with your access request and respond promptly to any requests for further information from the NDIA. If your situation is urgent, you can flag this to the NDIA and ask whether an expedited process is available. For the most current processing information, check (NDIS.gov.au) or contact the NDIA directly.
What if your access request is declined?
If the NDIA decides you do not meet the access criteria, you will receive a written decision explaining the reasons. You have the right to request an internal review of that decision through the NDIA. If you are still unsatisfied after an internal review, you can apply to the Administrative Review Tribunal (ART) for an independent external review at (ART.gov.au).
It is advisable to seek support from a disability advocate or legal aid service before lodging a review, particularly for tribunal proceedings. Many community legal centres offer free advice to people in this situation. Acting within the timeframes specified in your decision letter is important, as late applications may not be accepted.
Working with NDIS providers and managing your plan
Once your plan is approved, you can begin engaging with NDIS-registered providers to deliver your supports. All registered providers must comply with the NDIS Practice Standards and the Code of Conduct regulated by the NDIS Quality and Safeguards Commission at (NDIS Commission). You can search for registered providers using the provider finder tool on the NDIA website.
Your plan is typically reviewed annually, though you can request an unscheduled review if your circumstances change significantly. Reviews are an opportunity to adjust your supports and goals as your situation evolves.

Frequently asked questions
Q: Can I apply for the NDIS if I already receive a Disability Support Pension? A: Receiving the Disability Support Pension does not automatically make you eligible for the NDIS, nor does it exclude you. Eligibility is assessed separately against the NDIS access criteria. Contact the NDIA for guidance specific to your situation. Q: Do I need a formal diagnosis to apply? A: A formal diagnosis is not strictly required, but you do need evidence from a qualified health professional demonstrating the functional impact of your impairment. The NDIA assesses function rather than diagnosis alone. Q: What happens if my condition changes after my plan is approved? A: You can request an unscheduled plan review at any time if your support needs change significantly due to your condition worsening, improving, or changing in nature. Contact the NDIA or your LAC to initiate this process. Q: Can I change providers once my plan has started? A: Yes. You are not locked into any single provider once your plan begins. If you are self-managed or plan-managed, you have greater flexibility in choosing and switching providers. Even under NDIA management, you can request changes if a provider is not meeting your needs.---
