Australian citizenship by conferral vs descent: which pathway applies?

These are the two most common ways adults and children become Australian citizens — and they work very differently. Understanding which one applies to you determines what documents you need, whether you sit the test, and how long the process takes.

Official starting point: immi.homeaffairs.gov.au/citizenship/become-a-citizen

Quick answer

Your situation	Likely pathway
You are a permanent resident living in Australia and want to become a citizen	Citizenship by conferral
You were born overseas and one parent was an Australian citizen when you were born	Citizenship by descent
Your baby was born overseas and you are an Australian citizen	Citizenship by descent for the baby
Your child is under 16 and you are applying for citizenship by conferral	Include the child in your conferral application if eligible
You are already an Australian citizen but need proof	Evidence of Australian citizenship, not conferral or descent
You became eligible through marriage to an Australian citizen	Usually still citizenship by conferral after holding the right visa and meeting residence rules

If more than one row seems to apply, work from the source of citizenship first. A person born overseas to an Australian citizen parent should check descent before assuming they need the longer conferral pathway.

Citizenship by conferral

Conferral is the pathway for permanent residents who have lived in Australia for the required period and want to become citizens.

Who it's for:

• Permanent residents on most visa types
• People who have lived in Australia lawfully for at least four years, with at least 12 months as a permanent resident
• Must meet good character, English language, and knowledge requirements
• Usually people who were not already Australian citizens through birth or descent

What's involved:

• Online application through ImmiAccount
• Identity verification appointment
• Citizenship test (unless exempt by age or incapacity)
• Approval of your application
• Citizenship ceremony and pledge

The test draws from Our Common Bond and covers Australian history, government, and values. You need 15/20 correct and all five values questions right to pass. See the Australian citizenship test guide for the full format.

Processing time: Varies significantly. Check the Department's processing times page for current wait times.

For the full process, see step-by-step Australian citizenship application.

When conferral is the wrong pathway

Do not start with conferral if you may already be an Australian citizen or if you qualify through a parent. Common examples:

• You were born overseas to an Australian citizen parent
• Your child was born overseas and one parent was Australian at the time
• You need proof of citizenship after losing a certificate
• You were born in Australia and need to confirm whether you became a citizen automatically

In those cases, check descent or evidence of citizenship first. Applying under the wrong pathway can mean unnecessary fees, longer processing, or requests for evidence that do not fit your situation.

Citizenship by descent

Descent is for people born outside Australia who have at least one Australian citizen parent.

Who it's for:

• People born overseas whose parent was an Australian citizen at the time of their birth
• Babies and children born overseas to an Australian citizen parent
• Adults who were born overseas and are only now applying to have citizenship recognised
• Applicants whose Australian parent was also a citizen by descent, provided that parent meets the two-year residence connection requirement

What's involved:

• Application through ImmiAccount
• Evidence of your relationship to the Australian citizen parent
• Evidence that the parent was Australian at the time of your birth
• Extra evidence if the Australian parent was also a citizen by descent
• Approval and certificate of citizenship

No test, no ceremony. Citizenship by descent doesn't require sitting the citizenship test or attending a ceremony. You receive a certificate confirming your citizenship once approved.

The parent-by-descent rule

The most important descent edge case is where the Australian parent is also a citizen by descent.

If your Australian parent was:

• born in Australia, or
• became Australian by conferral/naturalisation,

then the descent pathway is usually straightforward if they were a citizen when you were born.

If your Australian parent was also a citizen by descent, they generally need to show a real connection to Australia through residence. The usual rule is that they must have spent at least two years living in Australia before citizenship can pass by descent to the next generation.

This matters for families living overseas across multiple generations. If this applies to you, read the descent page carefully and verify the rule with Home Affairs before applying.

Side-by-side comparison

	By Conferral	By Descent
Born where	Anywhere	Outside Australia
Main requirement	4 years residence, 12 months as PR	Australian citizen parent at birth
Needs permanent residency first	Yes	No
Main proof	Residence, identity, character, test eligibility	Birth certificate and parent's citizenship evidence
Citizenship test	Yes (with age/capacity exemptions)	No
Ceremony and pledge	Yes	No
Certificate issued	At ceremony	On approval
Common applicant	Migrant permanent resident	Overseas-born child or adult with Australian parent
Main risk	Lodging before residence requirements are met	Parent was not Australian at birth or parent-by-descent rule not met

Children: which pathway applies?

Children can fall into several different categories:

• Born in Australia to a citizen or permanent resident parent: the child may already be a citizen and may only need evidence.
• Born overseas to an Australian citizen parent: citizenship by descent is usually the pathway.
• Under 16 and included in a parent's conferral application: the child may become a citizen with the parent if eligible.
• Aged 16 or 17: the child usually applies separately, but is exempt from the citizenship test.

Documents: what changes by pathway?

Conferral and descent use different evidence.

For conferral, you usually prepare:

• passport and identity documents
• evidence of permanent residency
• travel history and residence evidence
• name-change documents, if relevant
• documents for children included in the application

For descent, you usually prepare:

• your birth certificate showing both parents' names
• proof your parent was Australian when you were born
• your identity documents
• evidence of the parent's two-year Australian residence if that parent was also a citizen by descent

For the practical document list, see Australian citizenship documents checklist.

Common mistakes

• Applying for conferral when descent is the cleaner pathway
• Assuming a baby born overseas is automatically Australian without applying
• Assuming marriage to an Australian citizen creates citizenship directly
• Including a 16 or 17 year old in a parent's conferral application when they need their own application
• Missing the parent-by-descent two-year residence rule
• Applying for a new citizenship pathway when you only need evidence of existing citizenship
