More information:

Citizenship by Descent

A person can obtain Australian citizenship by descent if one of their biological parents was an Australian citizen at the time of their birth. Citizenship by descent applicants must be registered as such before they apply for an Australian passport.

If the applicant’s parent also acquired their Australian citizenship by descent, the parent must have been present in Australia for periods totalling two years at some time in their life in order for the applicant to now be registered as an Australian citizen by descent.

How to apply

Citizenship by descent applications can be lodged online by visiting the Department of Home Affairs website.

Application fee

Information about the application fee and how to pay can be found on the Department of Home Affairs website.

Processing times & receiving the certificate in the mail

The Department of Home Affairs publishes its service standards online and aims to finalise 75 per cent of visa and citizenship applications within these timeframes.

Actual processing times are dependent on a number of factors, such as:

  • whether you have provided all necessary supporting documents when you lodge your application
  • how well and how promptly you respond to any requests for additional information
  • how long it takes to complete any required checks on information you have provided to support your application
  • volumes of applications received at any one time.

If your application is finalised and citizenship by descent is acquired, our office will print a certificate and mail it to the postal address provided.  Postal times may take 2-3 business days.  If your address changes, please advise our office by contacting the Americas Service Centre.

Please note that you should not book flights or make travel commitments until you have an Australian visa or Australian passport to travel to Australia. The department will not be liable for any financial loss incurred by clients whose visa or citizenship by descent application was finalised later than expected or where an application is unsuccessful.

Submitting supporting information

Applications can be lodged online and all supporting documents should be clear scanned copies uploaded to your application via your ImmiAccount.

For guidance on attaching documents to your online application, please visit the Department of Home Affairs website.

Please read the below tips on submitting supporting documents prior to lodging your application:

  • All copies of supporting documents, whether lodging online or by paper, must be clear and legible.
  • Do not send any original documents unless you are requested to do so by your case officer.
  • Documents not in English must be accompanied by a translation.
  • If you lodge a paper application by mail to the Australian Embassy, copies of your supporting documents should be certified.

Before you make an application you must ensure you have all of the required documents. If all the documents are not provided with the application form, the application may be deemed invalid and returned to the applicant with no further processing.

Good character documents

Citizenship by descent applicants aged 18 years or older are required to provide good character documents. 

If you are 18 years of age or older, you will need to submit a completed Form 80 and penal clearance certificates. 

For further information on good character documents and penal clearance certificates visit the  Department of Home Affairs website.
