Receiving a letter from the National Disability Insurance Agency (NDIA) stating that your access has been denied, or that specific supports have been cut from your plan, can be devastating. For many Australians, the NDIS is a lifeline. However, under the 2026 NDIS Reforms, the appeals process has been strengthened with new safeguards and faster decision timelines. A decline is not necessarily the final word. Participants now have enhanced review rights and clearer pathways to challenge unfair decisions.
In 2026, the NDIS has introduced significant reforms to improve transparency, fairness, and participant outcomes. These changes include enhanced decision-making frameworks, stricter evidence requirements from the NDIA, and improved appeal processes. If you’ve received a decline, this guide will walk you through the most common reasons for denial under the new 2026 framework, the legal steps to request an internal review, and how to escalate to the Administrative Review Tribunal (ART) if necessary.
In this guide, we will walk you through the most common reasons for funding denial, the legal steps to request an internal review, and how to escalate to the Administrative Review Tribunal (ART) if necessary .
What Decisions Can Be Reviewed by the NDIA?
Under the 2026 NDIS Reforms, not all NDIA decisions can be reviewed, but many can. The NDIS Act allows you to request a review for most major decisions. You have the right to challenge a decision if the NDIA decides to:
- You are not eligible for the scheme or that you are no longer eligible.
- To refuse specific supports in your plan (deciding something is not “reasonable and necessary”).
- To reduce funding for specific supports like therapy or core supports.
- To approve a plan that does not meet your needs.
- To not reassess or vary your plan when your situation changes.
If you have received a notice about any of these outcomes, do not ignore it. You have a strict deadline to act.
Why Was I Declined? The Most Common NDIS Funding Gaps
Understanding why the NDIA declined your request is the first step in building a successful appeal. The 2026 NDIS Reforms have introduced stricter, more transparent decision-making frameworks. Here are the most common reasons for funding refusal under the updated guidelines:
1. The “Reasonable and Necessary” Criteria
Under the 2026 NDIS Reforms, the NDIA applies stricter criteria when assessing whether supports are “reasonable and necessary.” The framework now requires comprehensive evidence linking your disability to your functional need. A support is typically declined under the 2026 standards if:
The NDIA will only fund supports that meet the strict criteria of being “reasonable and necessary.” This is the most common battleground for appeals. A support is usually declined if the NDIA believes:
- It is not related to your disability (e.g., general living costs like rent or groceries).
- It is the responsibility of another system (like health or education).
- It is likely to cause harm to you or others .
2. Lack of Clinical Evidence
Under the 2026 Reforms, the NDIA has implemented more rigorous evidence standards.They cannot approve funding based on anecdotal accounts alone. The 2026 framework requires current, professional assessments from registered practitioners—occupational therapists, speech pathologists, psychologists, or medical specialists. The evidence must clearly demonstrate how the disability creates a functional need for the specific support being requested. Outdated reports or general diagnoses without functional capacity assessments are typically declined.
The NDIA cannot approve funding based on feelings alone. If you did not provide recent, detailed reports from your occupational therapist, speech pathologist, or psychologist, the NDIA will likely decline the support. They need evidence that links the funding directly to your functional impairment.
3. Plan Management Confusion (2026 Clarifications)
Under the 2026 Reforms, the NDIA has clarified its approach to plan management. A decline in funding for a specific support is not always a funding denial—sometimes it’s a decision about how the support should be managed. The NDIA may insist on Agency-Management when you prefer Plan-Management, or vice versa. Under the 2026 framework, the NDIA must now justify its management preference with clearer reasoning linked to risk assessment, not general assumptions about participant capacity.
4. Respite and Support Independence Limits
Under the 2026 NDIS Reforms, the approach to respite care (Supported Independent Living or STA) and support funding has become more evidence-based. The NDIA can no longer cap supports based on arbitrary formulas or cost concerns alone. Under the 2026 framework, funding must be based on your demonstrated functional need and goals, not arbitrary caps. If the NDIA claims a support is “not value for money,” under 2026 rules they must provide detailed justification of their cost analysis and how it relates to your specific disability support needs.
The NDIA often caps “restricted” supports like respite care (SIL or STA) based on arbitrary formulas rather than your actual support needs .
Expert Tip from A1 Healthcare: If the NDIS claims a support is “not value for money,” we advise our clients to ask for a breakdown of their costing model. Often, the NDIA’s costings do not reflect the complex reality of your disability.
Step-by-Step Guide: How to Appeal an NDIS Decision
Under the 2026 NDIS Reforms, the appeals process has been streamlined with clearer timelines and more transparent decision-making. You must follow the formal review process established by law. There are now three stages: the internal review (NDIA), the external review (Administrative Review Tribunal), and legal support if needed.
Stage 1:The Internal Review (NDIA) – 2026 Updated Process
This is the mandatory first step. You cannot go to a tribunal until the NDIA has had a second look at its own decision .
The Deadline (2026 Rule): Under the 2026 Reforms, you have 3 months from the date you received the decision letter to request an internal review. It is critical you meet this deadline—applications submitted after 3 months may not be accepted.
How to Request:
You can request an internal review by:
- Calling the NDIS on 1800 800 110.
- Submitting the “Request for a Review of a Decision” form via the NDIS website.
- Sending a letter to GPO Box 700, Canberra ACT 2601 .
What to Include:
To win an internal review, do not just say “I disagree.” You must submit new evidence. Attach updated doctor’s letters or functional capacity reports that specifically address the reason for the decline. Clearly state why the original decision maker was wrong .
Can You Get a Priority Review?
Yes. If your situation involves risk of harm, instability in your living arrangements, or a deteriorating health condition, you can request a priority review. You must clearly mark your request as “Priority” and provide evidence of the immediate risk .
Stage 2: The External Review (Administrative Review Tribunal) – 2026 Enhanced Powers
If the NDIA completes their internal review and still denies your funding (or upholds a reduced plan), you have one more powerful option.
The Deadline: You have only 28 days from the date of the internal review decision to apply to the ART .
The ART is independent of the NDIA. They have the power to completely overturn the NDIA’s decision and substitute it with their own .
Important Updates (2025/2026):
Recent changes to legislation have altered the power of the ART regarding total funding amounts under the new “computer-assisted” planning model. However, for decisions regarding specific supports and eligibility, the ART remains a critical avenue for justice . According to recent data, the NDIA’s decision is overturned in nearly 73% of cases that reach the tribunal level, highlighting the importance of fighting for your rights .
Stage 3: Legal Support (NDIS Appeals)
You do not have to go to the tribunal alone. The NDIS Appeals program provides funding for disability advocates and legal services to help you through the external review process. You can search for an NDIS Appeals funded service in your area to get representation .
“People Also Ask” About NDIS Appeals
Do I need a lawyer to appeal an NDIS decision?
No, but expert help improves your chances. You can self-represent, or use a Support Coordinator or disability advocate. For complex ART hearings, legal advice is highly recommended .
Can the NDIS cut my funding while I am appealing?
Generally, no. While you are waiting for an internal review or external review, your current NDIS plan usually remains in effect. You are allowed to continue using your existing supports .
How long does an NDIS internal review take?
The NDIA aims to complete internal reviews within 60 days. If you have requested a priority review due to risk of harm, they are required to expedite this .
What happens if the NDIA ignores my review request?
If the NDIA fails to complete the review within a reasonable time (usually 90 days), this is considered a “deemed” negative decision. You can then proceed directly to the ART without waiting for their answer .
