How the NDIS works: a plain-English overview

What the NDIS is, who runs it, and how access, plans, funding and supports fit together.

The National Disability Insurance Scheme (NDIS) is Australia's way of funding supports and services for people with permanent and significant disability. It is designed to help you do the everyday things most people take for granted, build your skills, and take part in your community and work.

This guide explains the NDIS in plain English: what it is, who runs it, who it is for, and how you join and use a plan. Novida is an independent NDIS directory, not the government, so think of this as a friendly overview to help you understand how the whole system fits together.

What the NDIS is

The NDIS is a national scheme that funds supports for people with permanent and significant disability. Instead of a one-size-fits-all service, it gives eligible people an individual plan with funding they can use to buy the supports they need to live their life.

It is important to understand what the NDIS is not. It is not an income payment or a pension, and it does not cover everyday costs that everyone has, such as rent, groceries or utility bills. It funds supports that relate directly to your disability and help you pursue your goals, such as personal care, therapy, skill building, some equipment and help to get involved in your community.

The NDIS is built on an insurance model. That means it invests early in people, including younger children, on the basis that the right supports now can improve independence and reduce the need for more intensive help later. Official information about the scheme is published at ndis.gov.au and in the NDIS Our Guidelines.

Who runs it

The scheme itself is the NDIS. The agency that runs it day to day is the National Disability Insurance Agency, usually shortened to the NDIA. The NDIA decides who can access the scheme, works with you on your plan, and manages funding. When people talk about their 'planner' or 'access request', they are dealing with the NDIA.

A separate body, the NDIS Quality and Safeguards Commission, looks after the quality and safety of NDIS supports. It registers providers, sets standards of conduct, and handles complaints and serious incidents. If something goes wrong with a provider or you have a concern about your safety, the Commission is the body that can help.

Keeping these roles separate matters. The NDIA is about your funding and plan, while the Commission is about making sure the supports you receive are safe and delivered properly.

Who it's for

The NDIS is for people with a permanent and significant disability that affects their ability to take part in everyday activities. 'Permanent' means the disability is likely to be lifelong, and 'significant' means it has a substantial impact on how you manage everyday tasks and take part in life.

The scheme also includes early intervention. This is for people, including young children with developmental delay or disability, where getting supports early is likely to reduce the impact of their disability over time. Early intervention recognises that timely help can make a big difference to a person's independence.

Eligibility is about the functional impact of a disability, not simply having a particular diagnosis. If you are unsure whether the NDIS is for you, our separate guide on eligibility walks through the requirements in more detail.

How you join and use it

The NDIS journey usually follows a clear path. First comes access: you make a request to the NDIA and provide evidence about your disability and how it affects your life. If you meet the requirements, you become a participant.

Next is planning. You meet with the NDIA or a partner in the community to talk about your goals, your current supports, and what you want to achieve. From that conversation, a plan is created that sets out your funded supports and the budgets you can use.

You then use your supports. You choose providers, book services, and draw on your budgets to work towards your goals. Over time your plan is reviewed and reassessed to check it still fits your needs and circumstances, and it can be adjusted as your life changes.

What the NDIS funds (and doesn't)

Funding in a plan is grouped into three types of budget. Core supports help with everyday activities and your disability-related needs, and are the most flexible. Capacity Building supports help you build skills and independence, such as therapies, employment support and help to coordinate your plan. Capital supports cover higher-cost items like assistive technology and home or vehicle modifications.

Every support the NDIS funds must be 'reasonable and necessary'. In plain terms, this means the support is related to your disability, represents value for money, is likely to be effective, and is the responsibility of the NDIS rather than another system such as health, education or housing.

The NDIS is not meant to replace everyday services or the help of family and friends. It works alongside mainstream supports, like health and education, and alongside informal or natural supports, such as family, carers and community. The aim is to fill the gaps that relate to your disability, not to fund things everyone in the community pays for themselves.

Your choice and control

A core idea behind the NDIS is choice and control. As a participant, you have a say in the goals you set, the providers you use, and how your supports are delivered. You can change providers if a service is not working for you.

How your plan is managed also gives you options. Your funding can be managed by the NDIA, by a plan manager who handles payments and paperwork for you, or self-managed so you have the most direct control, or a mix of these. Each option offers a different balance of flexibility and support.

Making the most of your plan takes a bit of learning, and that is normal. Independent directories like Novida can help you find and compare providers, while ndis.gov.au and the NDIS Our Guidelines set out the official rules. The more you understand how the pieces fit together, the more confident you can be in using your plan.

Frequently asked questions

Is the NDIS the same as a pension or income support?
No. The NDIS is not income support and does not pay you a pension. It funds disability-related supports and services, such as personal care, therapy, skill building and some equipment. Everyday living costs that everyone has, like rent, food and bills, are not covered. Income support payments are separate and managed through other government systems, not the NDIS.
What is the difference between the NDIS and the NDIA?
The NDIS is the scheme itself, while the NDIA (National Disability Insurance Agency) is the agency that runs it. The NDIA decides eligibility, works with you on your plan, and manages funding. When you deal with a planner or lodge an access request, you are dealing with the NDIA. Both terms describe the same overall system from different angles.
What does the NDIS Quality and Safeguards Commission do?
The NDIS Quality and Safeguards Commission oversees the quality and safety of NDIS supports. It registers providers, sets standards for how they should behave, and handles complaints and serious incidents. If you have a concern about a provider or your safety while receiving supports, the Commission is the body to contact. It is separate from the NDIA, which manages your plan and funding.
What are the three types of NDIS budget?
NDIS plans group funding into three budget types. Core supports help with everyday activities and disability-related needs and are the most flexible. Capacity Building supports help you build skills and independence, such as therapies and employment help. Capital supports cover higher-cost items like assistive technology and home or vehicle modifications. Together they aim to match your goals and needs.
What does 'reasonable and necessary' mean?
Reasonable and necessary is the test the NDIS uses to decide what it will fund. In plain terms, a support must relate to your disability, represent value for money, be likely to be effective, and be the responsibility of the NDIS rather than another system like health or education. It should also take into account the help of family, friends and mainstream services.
Does the NDIS replace help from family or mainstream services?
No. The NDIS is designed to work alongside informal supports, like family, carers and community, and mainstream services such as health, education and housing. It fills gaps that relate to your disability rather than replacing the everyday help most people rely on. Your plan considers what these other supports already provide before funding disability-specific supports.
What are my options for managing my plan?
You can have your funding managed in a few ways. The NDIA can manage it for you, a plan manager can handle payments and paperwork on your behalf, or you can self-manage for the most direct control. You can also use a mix of these across your plan. Each option offers a different balance of flexibility, responsibility and support.
How often is my NDIS plan reviewed?
Plans are reviewed and reassessed from time to time to check they still fit your needs and goals. A reassessment may happen as your plan nears its end date, or sooner if your circumstances change. You can also ask the NDIA to look at your plan if your situation changes significantly. For current details, check ndis.gov.au or the NDIS Our Guidelines.
