 If you lodge an application with the AAT, we send a letter to confirm we've received it and tell you what will happen next. We also tell the department that made the original decision and any other party about the review. The department that made the decision is required to send the AAT a copy of the decision and all the other documents they hold that are relevant to the decision. They will also send copies to you and any other party except in most migration and refugee cases. In these cases, you or your representative can apply to us for a copy of the documents. Please ask for the documents as early as possible. We will write to you to let you know about the next step in the review which depends on the type of decision we're reviewing. We might write to you to ask for further information. We might hold a conference or directions hearing to talk to you and any other party about the case. Or we might list the case directly for a hearing. Please view our videos on conferences and hearings for more information about these types of events. You can give us new information when we review a decision. If you have new information you want us to look at, please give it to us as soon as possible. We might also write to you to invite you or direct you to give us information relevant to the review or comment on information by a certain date. It's important that you do this by the due date. You might be able to lodge documents through our online lodgement system. If you can't lodge documents online, we prefer you to send them by email. But we can also accept documents by fax or post or in person at our office. Please note that information you give us during the review process is usually given to the department that made the decision and any other party. In some cases, we ask you to take part in a directions hearing conducted by an AAT member. We will send you a letter with the date, time and location of the directions hearing. The directions hearing might be held in person at the AAT's offices or by phone or videoconference. The AAT member will usually talk to you and any other party about the issues the AAT needs to decide in your case, information that you or any other party will give us and by when, and the next steps in the review. If you can't attend the directions hearing for any reason, you must tell us as soon as possible. You should write to us, explain why you can't attend that day and send us any supporting documents such as a medical certificate. We only change the date if we're satisfied you have a very good reason. If you are the applicant in a review, you can choose to withdraw your application at any time. In most cases, you need to tell us in writing. You can contact us by email, phone or in person during the review. 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. You can find more information about the AAT by watching the other videos in this series, visiting our website, aat.gov.au or phoning us on 1800 228 333. Please note that AAT staff can help you with questions you have about our processes, but we cannot give you legal advice about your application.
