Australia Citizenship: The 365-Day and 90-Day Absence Limits

Australia’s general citizenship residence requirement includes two absence limits: 365 days across four years and 90 in the final year. Both sit alongside the lawful-residence and permanent-residence requirements.

Last verified: September 2026

In short: to apply for Australian citizenship by conferral you must have been living in Australia on a valid visa for the 4 years immediately before applying, holding a permanent visa or a Special Category (subclass 444) visa for the last 12 months. Two absence ceilings sit inside that history: no more than 12 months outside Australia across the 4 years, and no more than 90 days outside Australia in the final 12 months. Both periods are measured immediately before the day you apply.

Four-year allowance: No more than 12 months of absence, counted as 365 days
Final-year allowance: No more than 90 days of absence
A day counts if: You are outside Australia for the whole day
Other conditions: 4 years’ lawful residence; permanent visa or qualifying Special Category visa for the last 12 months
Applies to: Permanent residents applying for citizenship by conferral
Legal basis: Australian Citizenship Act 2007, s. 22, including its absence provisions

The rule

The general residence requirement is four conditions, all measured backwards from the day you apply:

Four years in Australia. You must have been living in Australia on a valid visa for the four years immediately before the application, and never here unlawfully.
Twelve months as a permanent resident. For the last of those four years you must hold a permanent visa, or a Special Category (subclass 444) visa.
At most twelve months away across the four years. Your absences over the whole four-year period must not add up to more than 12 months.
At most 90 days away in the final year. Your absences in the 12 months immediately before the application must not add up to more than 90 days.

Home Affairs’ published general-residence procedure counts the twelve-month absence allowance as 365 days. The calendar window still spans four years, including leap days; the allowance does not become 366 merely because a leap year falls inside it. The two absence ceilings are independent. Sitting comfortably under 12 months across four years does not help if the final year alone comes to 91 days, and a clean final year does not repair an over-long four-year total.

Neither window is a calendar year. Both run backwards from the day you apply, so the answer changes as that date changes: waiting a fortnight may move some older absences out of the final-year window.

How to count it

Fix the date you intend to apply.
Mark the final-year window: the 12 months immediately before that day.
Count every day in that window you spent entirely outside Australia. A day you fly out and a day you fly back are days spent partly in Australia, so they are not days away.
Add those days up across every trip. More than 90 and the final-year condition is not met on that date.
Separately, total every absence across the full four years and check it against the 12-month ceiling.

Example. You plan to apply on 1 September 2026, so the final-year window runs from 1 September 2025 to 31 August 2026. Three trips fall inside it.

Out 12 September 2025, back 11 October: 28 full days away. Out 20 December 2025, back 12 January 2026: 22 days. Out 3 May 2026, back 14 June: 41 days. Total 91 days, one day over.

Apply on 15 September 2026 instead and the window starts on 15 September 2025, dropping 13 and 14 September from the first trip’s absent days. The total falls to 89 days. The four-year window shifts by the same fortnight, so recheck that total as well.

The Department of Home Affairs publishes a Residence Calculator for estimating the result for an intended application date. It asks for lawful-residence and permanent-residence dates as well as travel movements. Review those inputs before lodging; the Department makes its assessment using its own records.

Check both totals. With 275 absent days in the earlier three years and 90 in the final year, the four-year total is 365. Both ordinary numerical limits are met exactly. With 270 earlier days and 91 recent days, the overall total is only 361, but the final-year limit is exceeded. With 276 earlier days and 90 recent days, the total is 366: only the longer-period limit is exceeded.

Australian citizenship absence calculator

Tap the day you left Australia, then the day you came back. The calculator counts the whole days you were away in the four years before your application date and compares them with 365 days. A second bar checks the last 12 months of that period against 90 days.

Timeline

Which territory counts as Australia?

The Australian Citizenship Act’s geographical definition includes the external territories. A stay in Norfolk Island, Christmas Island, the Cocos (Keeling) Islands or Heard Island and McDonald Islands is therefore not automatically an overseas absence for this test. Keep exact location records for less common territorial visits, including the Australian Antarctic Territory; a general record saying only “Antarctica” does not identify which sector was visited.

Beyond the day count

The absence ceilings are one part of the requirement, not the whole of it. Lawful status across the four years and permanent residence for the final year are separate conditions, and citizenship by conferral asks for more than residence. If your dates land close to either ceiling, that is a question for the Department's guidance or an immigration adviser, not for arithmetic alone.

The same absences run against other Australian clocks at the same time, and those clocks are not this one. A permanent visa carries its own travel facility, measured over its own period: see the Resident Return Visa residence requirement. Time in Australia is counted differently again for tax, where the window is the income year: see Australia's 183-day tax residency rule.

FAQ

How many days can you spend outside Australia before applying for citizenship?

Up to 90 days in the 12 months immediately before you apply, and up to 12 months in total across the four years before you apply.

Is the 90-day limit measured over a calendar year?

No. It runs backwards from the day you apply, so it moves with your application date and nothing about it resets on 1 January.

Does time spent overseas break the four-year residence period?

Absences are allowed inside the four years, up to 12 months in total and no more than 90 days in the final year. You must still have been living in Australia on a valid visa throughout.
