People living with disability often wonder what the phrase “reasonable and necessary” really means when they plan their NDIS packages. In Victoria, this term determines which supports the scheme will fund and how they are delivered. Knowing the definition, eligibility rules and funding process helps participants, families and support workers make informed decisions and avoid unexpected gaps in care.
What “reasonable and necessary” means and who it helps
The National Disability Insurance Scheme (NDIS) defines a support as “reasonable and necessary” when it:
- Is related to the participant’s disability.
- Is likely to be effective in achieving the participant’s goals.
- Provides value for money and is not wasteful.
- Is not available from other government services, the community or the participant’s own resources.
This definition applies to all participants in Victoria, whether they live in Melbourne’s inner suburbs or regional towns such as Belgravia, Chelsea or Pimlico. It covers a wide range of services – from personal care and therapy to home modifications and transport assistance – as long as they meet the four criteria above.
Eligibility & access rules
National eligibility criteria
To access “reasonable and necessary” supports, a person must:
- Be an Australian citizen, permanent resident or hold a protected visa.
- Be under 65 years of age when they first apply.
- Have a permanent and significant disability that impacts everyday life.
- Pass the NDIS functional assessment, which measures how the disability affects daily activities.
Victoria‑specific considerations
Victoria’s Disability Services Act aligns with the national framework, but the state government provides additional pathways for early intervention in areas such as the western suburbs of Melbourne. Participants living in Belgravia, Chelsea or Pimlico can access local disability liaison officers who help translate the national criteria into state‑specific service options.
What is included and what is excluded
Included supports
When a support meets the “reasonable and necessary” test, it can be funded. Typical examples include:
- Assistive technology (e.g., wheelchairs, communication devices).
- Therapeutic services such as physiotherapy, occupational therapy and speech pathology.
- Home‑based personal care and daily living assistance.
- Transport to enable community participation and access to health services.
- Home modifications that improve safety and accessibility.
Excluded supports
Even if a service is valuable, it may be excluded if:
- It is considered a “core” health service already covered by Medicare or the public health system.
- It is a lifestyle or convenience service (e.g., gym memberships, cosmetic treatments).
- It duplicates an already funded support in the participant’s plan.
- It is not directly linked to the participant’s disability goals.
Funding and planning considerations
Every NDIS participant receives a personalised plan that outlines funded “reasonable and necessary” supports. The plan is developed with a planner or support coordinator and must reference the latest NDIS Pricing Arrangements and Price Limits – the national framework that sets maximum rates for each support type. While the pricing tables do not show exact dollar amounts in this article, they ensure that participants receive consistent value across Australia.
Key points to remember when budgeting:
- Supports are grouped into categories such as Core, Capital and Capacity Building. “Reasonable and necessary” can appear in any category.
- Funding is allocated based on the participant’s goals, functional needs and the cost‑effectiveness of the support.
- Participants can request plan reviews if they feel a needed support was omitted or under‑funded.
- Providers must submit claims that align with the Pricing Arrangements; otherwise, the claim may be rejected.
How to request or activate a “reasonable and necessary” support
- Identify the need. Write down the specific goal (e.g., “I want to attend community events independently”).
- Discuss with your planner. During the planning meeting, explain how the support helps achieve the goal and why it meets the four criteria.
- Gather evidence. Provide medical reports, therapy notes or quotes from service providers that demonstrate effectiveness and value for money.
- Include it in the plan. The planner will record the support in the appropriate budget line, referencing the latest NDIS Pricing Arrangements and Price Limits.
- Choose a provider. Use the NDIS Provider Finder or local directories. For residents of Belgravia, Chelsea and Pimlico, consider providers who operate within the western Melbourne region.
- Start the service. Once the provider is approved, they will begin delivering the support and submit claims according to the agreed pricing schedule.
Local context for participants in Victoria
Living in the western suburbs of Melbourne offers several advantages when navigating “reasonable and necessary” supports. Belgravia, Chelsea and Pimlico each have community hubs that host disability information sessions and connect participants with local service providers. The Wyndham disability liaison office runs quarterly workshops that explain how to document evidence for plan meetings.
In Belgravia, the local council’s “Accessible Homes” initiative often partners with NDIS‑funded home modification projects, making it easier to align state and national funding streams. Chelsea’s community centre runs a peer‑support group where participants share tips on negotiating transport assistance under the “reasonable and necessary” framework. Pimlico’s regional health precinct offers a multidisciplinary clinic that can provide combined therapy assessments, which are useful when seeking bundled funding for allied health services.
When searching for providers, participants in these suburbs may also find specialised services listed on the NDIS provider directory, such as home‑care support agencies that have experience preparing claims that meet the Pricing Arrangements.

Frequently asked questions
What does “reasonable and necessary” actually mean for my NDIS plan?
It means the support must be related to your disability, help you reach your goals, provide good value for money and not be available elsewhere. If a support meets these criteria, it can be funded under the NDIS.
Can I claim any assistive device as “reasonable and necessary”?
Only devices that are essential for daily living, safety or communication, and that are not already provided by other health services, meet the test. The device must also be cost‑effective according to the latest NDIS Pricing Arrangements.
How often can I review my plan if I think a support should be added?
Participants can request a plan review at any time if their circumstances change. Most people schedule a review annually, but urgent changes can be addressed sooner.
Is transport to a community event considered “reasonable and necessary”?
Yes, if the transport enables participation in community activities that support your goals and there are no other affordable options. Evidence such as a travel quote and a goal statement will help the planner approve it.
What should I do if a claim for a “reasonable and necessary” support is rejected?
First, check the rejection reason against the NDIS Pricing Arrangements. Then, gather additional evidence or adjust the claim to meet the criteria and resubmit. You can also seek assistance from a support coordinator.
