Change of Details or Change of Situation Form

Tell the NDIA your circumstances have changed so your plan can be updated.

Who fills it in

A participant (or their representative) whose situation, needs or contact details have changed.

When you’d use it

When you move, your support needs change, your informal supports change, or you want to request a plan reassessment.

How to submit it

Attach supporting evidence and, if helpful, a short letter explaining what changed and why more or different support is now reasonable and necessary.

What the Change of Situation Form is

The Change of Details or Change of Situation Form is how you tell the National Disability Insurance Agency (NDIA) that something important in your life has changed. It's a formal way to keep your NDIS record accurate and, when needed, to ask the NDIA to take another look at your plan.

Think of it as your official update channel. Whether it's a simple detail like a new address, or a bigger shift in the support you need day to day, this form makes sure the NDIA has the right, up-to-date picture of your situation.

What it does and why it matters

The form does two main jobs. First, it lets you update your contact and personal details so letters, calls and payments reach the right place. Second, it lets you flag a change in circumstances, such as your disability support needs increasing, your living arrangements changing, or an informal support like a family carer no longer being available.

When your circumstances have changed enough that your current plan no longer fits, this form is also how you can request a plan reassessment. That gives the NDIA the chance to consider whether different or additional supports are now reasonable and necessary for you.

Who needs to use it

Any NDIS participant (or their nominee, guardian or authorised representative) can use this form. You'd typically use it after a life event, a change in your health or disability, a move to a new home or region, or when the people who informally help you can no longer provide the same level of care.

Families and carers often help complete it, especially when they've noticed the current plan isn't stretching far enough to keep the participant safe and well supported.

When and how to use it, and what happens next

Submit the form as soon as your situation changes rather than waiting for your next scheduled plan review. Attach supporting evidence, such as a recent letter or report from a treating professional, and consider adding a short cover letter explaining plainly what has changed and why more or different support is now needed.

Once received, the NDIA updates your details and, if you've asked for a reassessment, decides whether to proceed. You can start on the official NDIS page at ndis.gov.au. Processing times and current requirements can change, so check the latest guidance there before you submit.

About the Change of Details or Change of Situation Form

How do I tell the NDIS my situation has changed?
Use the Change of Details or Change of Situation Form. It lets you update personal details or report that your support needs, living arrangements or informal supports have changed. Attach supporting evidence and, if helpful, a short letter explaining what changed. You can start on the official page at ndis.gov.au under changing your plan.
Can I request a plan reassessment before my scheduled review?
Yes. You don't have to wait for your next scheduled review. If your circumstances have changed and your plan no longer meets your needs, you can request a plan reassessment through the Change of Situation Form. Include recent evidence showing why different or additional support is now reasonable and necessary.
What evidence should I attach to a change of circumstances request?
Attach recent, relevant evidence that shows what has changed, such as reports or letters from your treating professionals, allied health workers or specialists. A short cover letter summarising the change and why more or different support is now needed also helps the NDIA understand your situation quickly and clearly.
Do I need to update the NDIS if I move house?
Yes. Let the NDIA know when you move so your address and region are correct and your letters, calls and payments reach you. A move can also change what supports are reasonable and necessary, so it may be worth noting any change to your support needs at the same time.
How long does a change of situation request take?
Processing times vary depending on your request and the evidence provided. Simple detail updates are usually quicker than a full plan reassessment, which involves the NDIA reviewing your circumstances. For current timeframes and requirements, check the latest guidance on ndis.gov.au, as these can change over time.
