Get support when seeking a review of NDIS decisions in the Administrative Appeals Tribunal (AAT)

About NDIS Appeals Support

NDIS Appeals Support is available for people who want a decision of the National Disability Insurance Scheme (NDIS) reviewed at the Administrative Appeals Tribunal (AAT). Our role is to support people with disability and others affected by reviewable decisions through the appeals process.

All NDIS Appeals supports are free of charge.

NDIS Appeals support is not available to service providers.

Our Appeals support is available to people who live in the Greater Sydney area.

Ways we can help

If you have received the outcome of an internal review (sometimes called a ‘Section 100 Internal Review’) and are not satisfied with the result, we can assist you with your application to the Administrative Appeals Tribunal.

Our NDIS Appeals Advocate may assist you in a range of ways including,
1. explaining the review process, including what is involved in appealing to the AAT
2. helping to prepare documents
3. providing advice and skills so you can better represent yourself, or
4. attending AAT conferences and hearings to help you put your case to the AAT.

No. There is a step before appealing for a review of an NDIS decision at the AAT. You need to apply to the NDIA for an internal review. If you are unhappy with the outcome of the internal review you can apply to the AAT for an external review and access NDIS Appeal services.

The AAT can review a range of decisions made by the National Disability Insurance Agency. However, they can only review a decision if it has been internally reviewed by the Agency.


Some of the NDIS decisions that can be reviewed are

that a person does not meet the access criteria

to approve the statement of supports in a participant’s plan

not to review a participant’s plan

to approve a person or entity as a registered provider of supports

to revoke an approval as a registered provider of supports

to make, or not to make, a determination about who may do things on behalf of a child

to make, or not to make, a determination that a person has parental responsibility for a child, or

to appoint a plan nominee or a correspondence nominee.

1. Receiving T documents

After you have lodged an application with the AAT you can expect to receive a copy of the NDIA (National Disability Insurance Agency) decision and all relevant review documents within 28 days after being told the application has been received. These are called ‘T documents’.

T documents are provided under section 37 of the Administrative Appeals Tribunal Act 1975.


2. First Case Conference

A case conference is the first step in resolving your matter. It is an informal, private meeting arranged by the AAT. It can occur via the telephone or in person.

The first case conference will usually be held between 6 and 10 weeks after you have lodged your application.

Usually, case conferences last about 30 to 45 minutes, but they can last up to an hour or longer.

The NDIA will provide a statement of Issues outlining the position of the NDIA and the best way to progress the matter.


3. Subsequent Case Conference

After receiving your Statement of Issues in the first case conference you may go away and seek further information to provide to the NDIA to help clarify any questions the NDIA may require answered.


4. Conciliation Hearing

If the matter cannot be resolved, depending on the circumstances, the AAT may order a Conciliation Hearing to occur before the matter is listed for a Hearing.

“Conciliation is an informal, private meeting to help you and the National Disability Insurance Agency (the Agency) consider possible options to reach an agreement.” – AAT

“If your case plan includes conciliation, it will usually be held within 4 weeks after your case conference. Conciliation is conducted by an AAT Conference Registrar or Member and attended by you and the representative of the Agency.” – AAT


5. Hearing

“The hearing is an opportunity for you, and the representative of the National Disability Insurance Agency (the Agency), to present information and arguments to the AAT about the decision under review. You will be able to talk about why you disagree with the decision.” – AAT

“The hearing is relatively informal and will usually be conducted by one Tribunal Member. The Member is the person who will make a decision about the review”- AAT


6. Decision

Once the Hearing is concluded the Tribunal member will go away to consider all the information presented after which a decision is made. The decision is usually made within 3 months after the Hearing has concluded.

Family Advocacy is a state-wide advocacy organisation that has made a range of resources. The resources aim to help you navigate the AAT process.
