The Australian citizenship residence requirement, explained
The four tests behind Australia’s residence rule: 4 years living here, 12 months as a permanent resident, and the 365-day and 90-day absence limits.
Most people who become Australian citizens apply by conferral, and most of them need to meet the general residence requirement. It is often summed up as “four years”, but it is really four tests, all checked against the day you apply. Trips overseas can quietly move that day by months.
On the day you apply, you need all four:
- 4 years living in Australia on a valid visa,
- the last 12 months as a permanent resident,
- no more than 365 days away in those 4 years, and
- no more than 90 days away in the last 12 months.
The day you leave Australia and the day you come back both count as days in Australia.
What the rule says
The Department of Home Affairs sums up the general residence requirement on its Residence Calculator page:
“To be eligible for Australian citizenship by conferral, you must have: been living in Australia on a valid visa for 4 years immediately before the day you apply; held a permanent visa or a Special Category (subclass 444) visa (SCV) for the last 12 months immediately before the day you apply, and not been absent from Australia for more than 12 months in the past 4 years, and no more than 90 days in the 12 months immediately before applying.”
Every test looks back from the day you apply. That is why the same trip can be harmless for one application date and a problem for another.
The four tests, one by one
1. Four years living in Australia on a valid visa
Time on temporary visas counts here, such as student, work or partner visas, as long as you were living in Australia lawfully. If you first started living here on 15 February 2023, the four years are complete for an application on 15 February 2027.
2. Twelve months as a permanent resident
Your permanent visa must have been in place for the whole 12 months before you apply. New Zealand citizens on a Special Category visa meet this test with that visa.
3. No more than 365 days away in the 4 years
Home Affairs counts “12 months” of absence as 365 days. Its procedure’s worked example describes an applicant who “has not exceeded the 365 days (12 months) of allowable absences”.
4. No more than 90 days away in the last 12 months
This is the test that catches most people, because one long trip home can use it up. It is the 12 months immediately before you apply, not a calendar year, so it moves with your application date.
How absences are counted
Travel days are days in Australia. The department’s procedure, released under freedom of information, says: “Days where the applicant arrived from outside Australia or departed Australia are counted by ICSE as days in Australia for the general residence calculation.” A trip from 1 to 15 July is 13 days away. More on this in Do the day you leave and the day you return count?
Both look-back periods end the day before you apply. For an application on 5 October 2026, the 4 years run from 5 October 2022 to 4 October 2026, and the 12 months from 5 October 2025 to 4 October 2026.
The tests are judged on the day you apply, so trips after that day don’t change whether you met them. You may still need to be in Australia for later steps, such as appointments and the citizenship ceremony, so check with Home Affairs before you book.
A worked example: Sam’s Christmas trip
Sam first came to Australia on a temporary visa on 15 February 2023 and became a permanent resident on 10 August 2025. Here are Sam’s trips:
| Trip | Left | Back | Whole days away |
|---|---|---|---|
| UK for Christmas | 22 Dec 2023 | 15 Jan 2024 | 23 |
| New Zealand | 5 Jul 2024 | 28 Jul 2024 | 22 |
| UK, a long summer at home | 1 Jun 2026 | 20 Aug 2026 | 79 |
| UK for Christmas (planned) | 18 Dec 2026 | 20 Jan 2027 | 32 |
Without the planned Christmas trip, Sam can apply on 15 February 2027, the day the four years are up. Every test passes: 124 days away in 4 years, and 79 in the last 12 months.
With it, the 12 months before 15 February 2027 hold 79 + 32 = 111 days away. The 90-day test fails, and keeps failing until enough of the long summer trip has left the 12-month window. The earliest date that meets every test becomes 23 June 2027, more than four months later.
Move the application date and both look-back periods move with it. With the Christmas trip, Sam is away 111 days in the 12 months before 15 February 2027, so the earliest date that meets every test is 23 June 2027. Without it, it’s 15 February.
Sam has two simple fixes. A Christmas trip of 11 whole days away or fewer, such as leaving on 18 December and coming back on 30 December, keeps the 15 February date. Or Sam can keep the long trip and plan to apply in late June.
Plan trips against your application date, not today. The same trip can be fine for an application this month and a problem for one in six months’ time, because the 12-month window will have moved to include it.
Why our count can differ from the official calculator by a day
We tested CitizenDays against the Home Affairs Residence Calculator. In ordinary cases the two agree. In two edge cases the calculator was one day more generous than the written rules: it accepted 366 days away in 4 years, and it didn’t count a day away that fell on the first day of a look-back period. The written guidance says 365 days, and the Act says “the period of 12 months immediately before”, so CitizenDays counts both. The effect is that our earliest date can be a day later than the calculator’s, never earlier.
The lesson is the same whichever tool you use: if you are within a day or two of a limit, leave yourself a margin.
What this rule doesn’t cover
- Special residence requirements in sections 22A and 22B of the Act, for “persons engaging in activities that are of benefit to Australia” and “persons engaged in particular kinds of work requiring regular travel outside Australia”.
- Discretion. The Minister can treat some periods differently in particular circumstances.
- Other conferral requirements, such as the citizenship test and good character.
If any of these might apply to you, read the Home Affairs guidance or ask a registered migration agent.
The paperwork: your travel history
Form 1300t, the citizenship application, asks you to “list all countries, in date order, that you have lived in or travelled to in the last 10 years”, with the dates of each trip. Home Affairs can give you its own record of when you left and entered Australia: its international movement records “show your entries and exits from Australia”, but not where you went. For everything else, see How to rebuild your travel history.
Questions people ask
Does time on a student or work visa count?
Yes, towards the 4 years of living in Australia on a valid visa. It doesn’t count towards the 12 months as a permanent resident.
Is “12 months” of absence the same as 365 days?
For the 4-year limit, Home Affairs counts 365 days. CitizenDays does the same.
Does the 90-day limit reset each calendar year?
No. It covers the 12 months immediately before the day you apply, so it moves with your application date.
Do the days I fly out and fly home count as days away?
No. Both count as days in Australia.
Can I apply on the anniversary of my arrival?
If you first lived here on 15 February 2023, the 4 years run to 14 February 2027, so 15 February 2027 is the first possible day, as long as the other three tests pass.
