Australian citizenship by descent is for people born outside Australia to a parent who was an Australian citizen when they were born. It generally requires proof of the parent-child relationship, the parent's citizenship, and extra residence evidence if the parent was also a citizen by descent.

Summary

Australian citizenship by descent is for a person born outside Australia whose parent was an Australian citizen at the time of the birth. For a person born outside Australia on or after 26 January 1949, that parent-at-birth link is the central rule.

If the Australian parent became a citizen by descent, or through a qualifying overseas adoption, an extra connection rule normally applies: the parent must have spent at least 2 years in total lawfully in Australia before the applicant applies. Those 2 years do not have to be before the applicant's birth and do not have to be continuous.

An eligible person does not become a citizen merely by having an Australian parent. Citizenship by descent is acquired when Home Affairs approves the application. The applicant can apply from inside or outside Australia.

Eligibility

The usual requirements for someone born outside Australia on or after 26 January 1949 are:

The word "parent" is a legal relationship, not simply a DNA result. Birth registration, adoption, parentage orders and surrogacy arrangements can affect which route and documents apply. Home Affairs has separate guidance for international surrogacy, and difficult cases should be assessed before relying on a genetic connection alone.

The evidence normally includes:

Someone born before 26 January 1949 is not covered by the ordinary modern statement above. Historical British-subject, Australian citizenship and territorial rules may apply and need a date-specific status assessment.

What This Route Allows

If approved, the applicant becomes an Australian citizen on the approval date. They receive citizenship evidence and can then apply for an Australian passport. An adult citizen must enroll and vote when legally required and may access rights and roles reserved for citizens.

Australia generally permits dual citizenship. The applicant must separately check the law of every other nationality they hold or may acquire.

Citizenship obtained by descent can be passed to a child born outside Australia only if the future application meets the law then in force. Under the current rule, a parent who is themselves Australian by descent generally needs 2 total lawful years in Australia before their child's application. This is a connection requirement, not an automatic end to the family line.

What This Route Is Not

An Australian grandparent alone is not enough. The applicant must show that their own parent was already an Australian citizen when the applicant was born. If the parent became Australian later, that later grant does not ordinarily make the earlier-born child eligible by descent.

The parent need not have completed the 2 lawful years before the child's birth. Describing that as a pre-birth rule wrongly excludes families where the parent lived in Australia later; the official test is completion before the citizenship application.

This is not automatic citizenship and it does not provide a bridging visa. A person traveling to Australia while the application is pending still needs a valid passport and any required Australian visa. Approval is also not retrospective to the birth date.

Next Steps

  1. Obtain the applicant's long-form birth certificate and documents proving the legal parent-child relationship.
  2. Establish exactly how and when the parent became an Australian citizen, and prove that status existed on the applicant's birth date.
  3. If the parent was Australian by descent or qualifying overseas adoption, total all lawful time they spent in Australia before the planned application. Obtain movement, school, employment or government records.
  4. Resolve spelling, transliteration, adoption, surrogacy or name-change gaps with official documents and English translations.
  5. For an applicant aged 18 or older, review the current police-certificate and good-character instructions before applying.
  6. Apply through ImmiAccount using the current Home Affairs checklist. If approved, safeguard the citizenship certificate and then apply separately for a passport.
