For the Australian Government to determine whether you are of good character, you may be asked to provide police certificates for each country you have lived in for 12 months or more over the last ten (10) years since turning 16.
If you are applying for conferral of Australian citizenship and you have spent 12 months or more overseas after grant of a permanent visa you need to provide overseas penal certificates for those other countries in which you have resided.
但是后面还有一段,搞得我很糊涂
Note: For all applicants, periods spent overseas since the applicant turned 18 years of age should be considered.
Residence overseas can be a continuous period or cumulative periods totalling 12 months or more. Penal certificates are only required where the period of stay in any one country exceeds 3 months or more.
