Notes
Standard adult pathway (citizenship by conferral / general eligibility): applicant must have lived in Australia lawfully for 4 years immediately before applying, which must include the last 12 months as a permanent resident. Absences must not exceed 12 months total in the 4-year period, including no more than 90 days in the 12 months immediately before applying. Applicants must meet good character requirements; Home Affairs may require police/penal clearance evidence depending on circumstances and travel/residence history. Lodgement is generally preferred online via ImmiAccount; applicants may be required to attend a citizenship test/appointment and later a citizenship ceremony.
Dual citizenship
Dual citizenship: Allowed
Renunciation required: No
Special cases: Australia allows dual citizenship; however, whether the person can keep another nationality depends on the other country’s laws, and practical travel/document rules apply for dual nationals.
Notes for dual citizenship
Dual/multiple citizenship is generally allowed by Australia and renunciation is not required by Australia for naturalisation; applicants should confirm the other country’s rules and travel documentation obligations.

Qualifying residence permits

New Zealand citizen – Special Category visa (SCV)
Form 1300t notes special eligibility conditions for certain New Zealand citizens holding an SCV; residence/PR-start-date rules may differ for this cohort.
Counts
Permanent resident (any permanent visa holder)
General residence requirement includes the last 12 months as a permanent resident and typically requires being a permanent resident when applying for citizenship by conferral.
Counts
Temporary visa holder (any valid Australian visa)
Time on a valid Australian visa can count toward the 4-year lawful residence period, but the last 12 months must be as a permanent resident.
Counts
Unlawful / expired status
Unlawful presence does not meet the standard “lawful residence” concept; some limited discretions may apply in narrow administrative-error scenarios, but unlawful status is not a qualifying permit type.
Doesn’t count
