Sending us documents

Instead of emailing, if you have an existing matter at the AAT, you can submit your documents online.

This allows for faster processing and larger file sizes than emails.

Find out more in our document submission user guide

Who do I email if I have a case at the AAT?

We will tell you the email address to use when we write to you. Our email addresses are: 

Centrelink and child support decisions
Migration and refugee decisions
All other decisions


You must not send an email directly to an AAT Member or AAT staff.

Who else should I email?

If your email is about a case in any division other than the Migration & Refugee Division or the Social Services & Child Support Division, please send a copy of your email to the other party.

Is there any information I should include in the subject line of my email?

You should always include the AAT case or review number in the subject line of your email in any case that has already been lodged with the AAT. It can usually be found on any letter or other document from the AAT.


Subject: 2019/1000 — Applicant Name and Department Name — Additional documents

What can’t I submit online or send by email?

You should not email or submit documents online if you are:

  • an agency or organisation whose decision we are reviewing and you are sending us section 37 documents (T-documents). These should be sent in hard copy.
  • a person sending documents required by a summons to produce documents. These should be sent in hard copy, or on a CD or USB drive.

What types of files can I send?

  • Microsoft Word (.doc or .docx)
  • Microsoft Rich Text (.rtf)
  • Microsoft Excel (.xls, .xlsx)
  • GIF, JPEG and PNG image files (.gif, .jpg, .png)
  • Portable Document Format (.pdf)

We do not accept zipped or archive files.

If you are sending us a PDF file, we prefer if it is a searchable PDF document.

Are there any size limits for emails or documents?


When you submit documents online, you can upload single documents up to 10MB in size, with a maximum of up to 50MB for all documents.

We do not accept emails, or a series of emails, larger than 10MB or longer than 100 pages or attaching documents with a total of more than 100 pages. Large documents should be sent to the AAT in hard copy.

Do I need to send a hard copy too?

No. You do not need to send us a hard copy of a document unless we ask you to.

We might ask you to send us documents in hard copy if:

  • they are not a file type listed above
  • they are larger than 10MB or 100 pages, or
  • they are unclear or confusing when sent electronically.

Will you confirm that you have received my email?

When you submit documents online, we will send you an email and reference number confirming that we have received the documents.

If you send documents via email you will not receive an automatic acknowledgement that the AAT has received your email.

If your email is urgent, you should also phone the AAT to let us know you have sent the message. This will ensure the message is actioned as soon as possible.

When will the AAT not respond to your email?

If you send an email including inappropriate or offensive material:

  • your email may be blocked or rejected;
  • the AAT may choose not to communicate with you by email in the future; and
  • the AAT may report the matter to the appropriate authorities.
