Citizenship by Descent

Citizenship by Descent

A person born outside Australia who is the natural child of an Australian citizen parent may acquire Australian citizenship by descent.  A person becomes a citizen on the date they are registered as an Australian citizen by Home Affairs. A certificate of Australian citizenship is issued at the time of registration.

For more information including eligibility requirements and how to prepare your application, go to Become an Australian citizen (descent).

Apply Online

You can now apply to be registered as an Australian citizen by decent online through ImmiAccount.  This is the preferred and most efficient way to apply.

Providing documents online

Please ensure that in all cases you submit colour scans of the original documents (not certified or notarised copies) together with English translations at the time of application. 

All supporting documents should be a clear, high quality scan (at least 300 dpi resolution, up to 2MB in size). If you attach low quality scanned documents, processing of your application may be delayed.

If you have any enquiries or issues regarding your ImmiAccount, including information on how to upload documents online, please go to Applying online in ImmiAccount.

Processing Times
