How to Apply for SDA Funding and Update an NDIS Plan

You may know your current home isn’t working for you. Explaining that through forms, assessments and NDIS planning conversations can feel like another challenge altogether. 

Perhaps you’re exploring Specialist Disability Accommodation (SDA) for the first time. You might already have an SDA decision but need your plan updated before moving. Or you may be trying to understand why a request was declined. 

Each situation has a different next step. SDA funding is requested through the NDIA, which considers your housing needs and supporting evidence. Choosing a property and arranging everyday support are related parts of the process, but they involve separate decisions. 

Here’s how to work out where to begin, who can help and what to prepare. 

Where to Apply for SDA Funding and Support Services? 

Start with your my NDIS contact and explain that you want the NDIA to consider SDA as part of your home-and-living supports. If you already have an SDA decision, ask whether you need a plan update rather than a new eligibility assessment. 

You don’t need to begin with a property address. Start with what is difficult about your current living arrangement and how your disability affects your housing needs. 

For example, you might explain that there isn’t enough space for essential equipment, that personal care is difficult to deliver safely, or that your current arrangement no longer provides the assistance you need. 

Identify the Decision You Need 

Being clear about your situation helps the conversation move forward. 

A plan variation changes part of an existing plan. A reassessment considers a more significant change and can result in a replacement plan. Your my NDIS contact can help clarify which process fits your circumstances.

If you’re still exploring whether specialist housing may be relevant, our SDA eligibility checker can help you prepare questions. It doesn’t replace an individual assessment or an NDIA decision. 

Keep Housing and Daily Support Connected 

An SDA housing provider can explain a dwelling’s features, agreements and availability. It cannot allocate NDIS funding. 

You’ll also need to consider assistance inside the home. SDA funding relates to specialist housing, while supports such as personal care or SIL are arranged separately.

Discuss both early so you’re planning for a workable living arrangement, including the support needed from the day you move. 

Who Can Help Me Apply for SDA Funding? 

A support coordinator, occupational therapist, other treating professional, independent advocate or trusted person may help you prepare an SDA request. Their contributions differ, so clarify who is gathering evidence, who is helping with the request and what each service costs. 

An occupational therapist may assess how your functional abilities, equipment and environment affect daily life. Other treating professionals may contribute relevant medical or functional information. 

A support coordinator, if funded, may help connect you with assessors and organise the process. An advocate can help you understand your rights and communicate what matters to you. 

Agree on Roles Before Paying for Help 

Ask anyone offering application assistance: 

• What will you do, and what will I need to do? 
• What documents or reports will I receive? 
• What are the fees and expected timeframes? 
• Will you review existing evidence before recommending another assessment? 
• How will I be involved in decisions? 

A useful service should be able to explain its contribution without promising approval. 

For plan reassessment requests, current NDIA guidance says the request form must be submitted by the participant, plan nominee or child representative. Other people can help prepare it, but their involvement doesn’t automatically authorise them to submit the request. 

Where someone is helping communicate with the NDIA, confirm the appropriate consent or representative arrangements too. 

Get Help With an SDA Application

Begin by asking your my NDIS contact what request and evidence are needed, then organise your information around the housing problems you want addressed. A clear account of everyday needs is more useful than a large collection of documents with no explanation of how they relate. 

You don’t have to prepare everything alone. Breaking the work into a few manageable steps can make it easier. 

Explain What Isn’t Working 

Write a short account of your current home and support arrangement. Include what you manage independently, what assistance you receive and where difficulties arise. 

For a hypothetical participant who cannot use the bathroom safely, useful information might describe: 

• The space available for equipment and assistance. 
• The tasks that are difficult. 
• How often help is needed. 
• Changes or equipment already considered. 
• Why the current arrangement remains unsuitable. 
• Keep the description accurate. You don’t need to exaggerate difficulties to explain why they matter. 

Review What You Already Have 

Bring together relevant assessments, your current plan, previous decision letters and information about your support needs. 

Ask which documents remain useful and what gaps need addressing before commissioning further reports. An assessment should answer a clear question, such as how your home environment affects daily functioning or why another housing option may not meet your needs. 

Keep a Simple Record of the Request 

Store copies of what you submit and note the date, method of submission and any reference number. 

A short covering explanation can help connect the documents: 

“I’m requesting consideration of SDA because my current home no longer meets my disability-related needs. The attached assessment explains the access barriers, assistance required and options considered.” 

Request confirmation that the information has been received. If more evidence is requested, ask what question it needs to answer. 

Clear follow-up is part of good support. Whoever is helping you should be able to explain what has been submitted, what is outstanding and who is responsible for the next step. 

Where Can I Find Information on SDA Funding Appeals? 

Start with the NDIA’s decision-review guidance and the written reasons for your SDA decision. For a reviewable decision, you generally have three months from receiving it to request an internal review; the Administrative Review Tribunal (ART) provides an external review pathway where applicable. 

A disappointing decision can be hard to read, particularly when you’ve already spent time explaining your needs. Before preparing a response, identify exactly what the NDIA decided and why. 

Was SDA declined altogether? Was a particular arrangement not supported? Does the plan differ from an earlier written decision? 

Those distinctions help you respond to the issue that needs reconsideration. 

Make the Review Request Specific 

Explain: 

• Which decision you want reviewed. 
• What outcome you were seeking. 
• Why you believe a different decision should be made. 
• Which existing evidence you want reconsidered. 
• Whether you have additional relevant information. 

These are the matters the NDIA asks you to address in an internal review request.

For example, if the reasons suggest that ordinary housing could meet your needs, relevant evidence may need to explain which alternatives were considered and why they would not work. 

Check the deadline early. If reports are still being prepared, contact the NDIA about making the review request within time and providing further information. 

Understand the External Review Pathway 

An ART application is generally due within 28 days of receiving the NDIA’s internal review decision. The Tribunal also provides a pathway where 90 days have passed since an internal review was requested without a decision. Check its current instructions for your situation. 

Independent advocacy or legal assistance may help you understand the reasons, organise evidence and navigate the process. 

If your needs have changed since the original decision, raise that as well. Challenging an earlier decision and asking for support because of new circumstances can involve different processes. 

How to Modify an NDIS Plan to Include SDA Funding 

Contact your my NDIS contact, explain the change you need and ask whether a variation or reassessment is appropriate. If SDA has already been approved, establish whether you need the plan to reflect that existing decision or a new decision about changed needs. 

Describe what has changed, when it changed and why the current plan no longer works. A different address alone doesn’t necessarily mean you need a fresh SDA eligibility assessment. 

Understand the October 2026 Funding Update 

From 19 October 2026, approved NDIS plans include the full SDA amount a participant is eligible for, whether they already live in SDA or are still searching. 

The NDIA says this changes how funding appears in the plan. It does not change eligibility decisions, the eligible amount or provider claiming arrangements. 

Participants with a $1 placeholder or less than their full eligible amount will generally have this updated at their next reassessment. Those moving into SDA may be able to request an earlier update through a change of circumstances. 

If your plan still shows a small placeholder, ask the NDIA to explain your recorded SDA decision and whether an update is needed for your proposed move. 

Check the Details Before Moving 

Before committing to a dwelling, confirm that it fits your approved SDA arrangements and that the housing provider can explain the agreements and charges. 

You must tell the NDIA when you move into a new SDA home. Your SDA provider must also be recorded as a my provider, and you need a written SDA service agreement. 

Alongside those steps, organise the practical handover: equipment, daily support, worker preparation and any changes to your existing services. 

A funding update is one part of the move. Knowing who will assist you on the first morning is another. 

Preparing Your Next Step 

Start by identifying whether you need a first SDA decision, an update to existing funding or a review of a decision. Gather your current plan, relevant reports and a short explanation of the housing issue, then discuss the appropriate pathway with your my NDIS contact.
