Should I send a document to the AAT by email or online?

The best way to send documents to the AAT is online. Our online systems allow for faster processing and larger file sizes than emails.

You can use our online services portal to:

  • lodge a new application, or
  • send us documents in a case already lodged with the AAT.

If I need to send an email to the AAT, what is the best email address?

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

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


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

Who else should I email?

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

What should I 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 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. We cannot accept attachments that link to cloud based storage, such as Google Drive or Dropbox.

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

Are there any size limits for emails?


We do not accept emails larger than 10MB.

When you submit documents online, you can upload single documents up to 15MB in size, with a maximum of up to 50MB for all documents.

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.
