* 4 years lawful residence in Australia. This period must include 12 months as a permanent resident immediately before making an application for Australian citizenship
Please note that absences from Australia cannot exceed a total of 12 months in the four year period, including no more than 90 days in the last 12 month permanent residence period prior to application.
Please note that any time you spent in Australia before you were granted permanent residence status, does not count as permanent residence.
If you were granted a migrant visa offshore your permanent residence date is your date of first arrival in Australia on this visa.

If you are a permanent resident but have not lived in Australia for the required length of time, the normal residence requirements may not apply to you in certain circumstances.
