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 go to Become an Australian citizen (descent).
