 The AAT reviews decisions made by Australian government ministers and departments and other organisations under Commonwealth laws. If you've received a decision you think is wrong, you might be able to apply to us for a review. For some decisions, you might have to apply to the department for an internal review before you can apply to the AAT. The decision or information sent with it should tell you whether we can review the decision. Contact us if you're not sure. The best way to apply for a review is online through our website. Our system will help make sure you give us all the information we need to start the review. You can also complete an application form and give it to us at an AAT office or send it to us by email, fax or post. For some Centrelink and Child Support review applications, you can phone us to lodge your application. For many decisions, you have a time limit to apply for a review. Check your decision or information sent with it to find out if there is a time limit and what it is. We might be able to extend the time limit you have to apply for a review, but not for most migration or refugee decisions. There is no fee to apply for a review of some kinds of decisions, including Centrelink and most child support decisions, as well as NDIS, veterans entitlements and workers' compensation decisions. For other types of decisions, the amount of the fee varies. It can be reduced in some circumstances, including for financial hardship. If a fee applies, you should pay the fee when you give us your application. Your application fee might be partially refunded if your review is successful. More information about fees is on our website. If we think there is any kind of problem with your application, such as not meeting a time limit, we'll contact you. You don't need to have a lawyer or other representative when you come to the AAT. However, you can arrange one if you want to. Depending on the type of decision being reviewed, this could be a lawyer, migration agent, tax agent or veteran's advocate. It could also be a disability advocate, family member or friend. Please tell us in writing if you appoint a representative or an authorised person to receive documents on your behalf. They will be able to communicate with us and receive all documents on your behalf. We will usually only send copies of documents to your representative or authorised recipient. You can usually have a support person such as a disability advocate, family member or friend help you with your case and when you come to the AAT. We can give you information on legal aid services, community legal centres and other organisations that might be able to provide advice and assistance. If you need an interpreter, please let us know. We'll arrange for a qualified interpreter to assist you free of charge during the review. Please also tell us if you require assistance because of a disability so we can try to make appropriate arrangements for you. Once you lodge your application, we'll send you a confirmation letter and information on what will happen next. All information given to us is handled in accordance with the Australian Privacy Principles and other legal requirements. To assess your application and conduct a review, we collect information from you or your representative from the department that made the decision and sometimes from other people. We usually give a copy of any information we receive to the department that made the decision and any other party and sometimes to other people where this is required. We'll give you information about who we usually collect information from and who we usually give it to. Our privacy policy explains how we handle information and is available on our website. You can contact us by email, phone or in person during the review, details of how to contact us are on our website. It's important that you tell us immediately if your address or any of your contact details change during the review so we're able to contact you.
