Citizenship Residence Requirement: The Four-Year and 90-Day Rules

Ask someone what the residence requirement for Australian citizenship is and you will usually be told "four years". That is one quarter of the answer.

Home Affairs sets out the general residence requirement as four conditions, and they measure different things over different windows. It is entirely possible to have lived in Australia for a decade and still fail — because two of the four tests are about absence, and one of those looks only at your most recent twelve months.

Understanding them as separate tests is what turns a vague worry into a date you can check.

The four tests

The general residence requirement is that, when you apply, you must have:

1. been living in Australia on a valid visa for 4 years immediately before the day you apply
2. held a permanent visa or a Special Category (subclass 444) visa for the last 12 months immediately before the day you apply
3. not been absent from Australia for more than 12 months in total in the past 4 years, and
4. been absent no more than 90 days in total in the 12 months immediately before applying

Every one of those phrases ends in "before the day you apply". The whole requirement is a backwards-looking window anchored on your lodgement date, which is the single most useful thing to understand about it.

Test one: four years on any valid visa

This is the test people most often misread, and they misread it in the harder direction.

The four years is time living in Australia on a valid visa — any valid visa. Time on a student visa counts. Time on a working visa counts. Time on a temporary visa before you were granted permanent residence counts.

You do not need four years of permanent residence. If you have been in Australia lawfully for four years and only became a permanent resident recently, test one is likely satisfied.

Test two: twelve months as a permanent resident

The permanent-residence requirement is separate, and it is much shorter: you must have held a permanent visa or a Special Category (subclass 444) visa for the last 12 months before you apply.

So the two front-end tests work as a pair. Four years of lawful residence, of which the most recent twelve months must have been as a permanent resident or SCV holder.

This is where someone with a long history in Australia can still be too early. Ten years on temporary visas plus eight months of permanent residence passes test one and fails test two, and no amount of prior residence fixes it — only waiting does.

One point for New Zealand citizens: if you hold an SCV, you continue to be considered a permanent resident for citizenship purposes while outside Australia, provided you held the SCV immediately before you departed.

Test three: twelve months of absence across four years

Across the four-year window, your total time outside Australia must not exceed twelve months.

Note in total. This is cumulative across every trip, not a limit on any single one. Four separate three-month absences reach the limit exactly as one twelve-month absence would.

Test four: 90 days in the final year

Within the last twelve months before you apply, your total absence must not exceed 90 days.

This is the test that ends most applications before they start, for three reasons:

Ninety days is not very long. Three weeks home for a wedding, two weeks of leave and a fortnight for a family emergency is already most of it.

It is cumulative. As with test three, "in total" means every trip added together.

It sits inside test three, not beside it. The final twelve months are part of the four years. Days absent in that period count towards both limits.

Worked examples

The arithmetic is straightforward once the windows are clear. Take an application lodged on 1 March 2027.

The windows:

• Test one looks at 1 March 2023 to 1 March 2027 — you must have been living in Australia on a valid visa throughout.
• Test two looks at 1 March 2026 to 1 March 2027 — you must have held a permanent visa or SCV throughout.
• Test three totals your absences between 1 March 2023 and 1 March 2027 — the total must not exceed twelve months.
• Test four totals your absences between 1 March 2026 and 1 March 2027 — the total must not exceed 90 days.

Someone who fails only test four

Six weeks overseas in June 2026, then a five-week trip booked for January 2027. That is roughly 77 days, which is fine. Add a two-week trip in October 2026 and the total passes 90 days — and the four-year total may still be well under twelve months. Three tests passed, one failed, application not ready.

Someone who fails only test two

In Australia continuously since 2019 on student and then work visas, granted permanent residence in August 2026. Tests one, three and four are all comfortably met. Test two is not satisfied until August 2027.

Someone who fixes it by waiting

Because the windows move with your lodgement date, an absence eventually falls out of the twelve-month window. Someone who used 100 days by December 2026 may be under 90 days by mid-2027, simply because the early trip has aged out. Delaying your application is a real remedy, not a consolation.

Children under 16

Children under 16 do not need to meet the general residence requirement, but they must be permanent residents.

That is a genuine exception rather than a relaxation, and it means a family can be in a position where the parents must wait and the children need not.

What is not covered by these four tests

Two things sit outside the general requirement and are assessed separately once an application is lodged.

Ministerial discretions may assist a person to meet the residence requirement in defined circumstances — for example, where time in Australia was affected by administrative error, or where a spouse or de facto partner of an Australian citizen spent time overseas while maintaining a close and continuing association with Australia. These require supporting evidence, and Home Affairs states that eligibility for a discretion cannot be assessed in advance of an application.

Special residence requirements apply to particular groups, including people engaged in certain work requiring regular travel outside Australia and people who need citizenship to represent Australia in specific activities. Those have their own, different day counts.

Neither is a general escape from the four tests, and neither should be assumed before applying.

How to check your own position

1. Pick a lodgement date. Everything is measured backwards from it, so nothing can be calculated without one.
2. Write the four windows out as actual dates, the way the example above does.
3. Get your real travel dates. You can request your international movement records from the Department free of charge, which is more reliable than reconstructing them from memory.
4. Total the absences for each window separately. Do not compute one number and use it twice — test three and test four cover different periods.
5. Include trips you have booked but not taken, if they fall before your lodgement date.

If a window fails, move the lodgement date later and recalculate. That is usually the whole solution.

Before you lodge

Home Affairs assesses residence from its own records at the time you lodge, so an estimate you have made is not a decision. If you are within a few days of any limit, waiting a little longer costs far less than lodging an application that cannot succeed.

The rules are published by Home Affairs and can change, so check the current official guidance before relying on any calculation.
