@urjoanjoory Need ng NBI clearance sis. Also as far as I know, need talaga ng police clearance if nag-stay ka sa isang country for 12 months or more. Eto nakalagay sa website nila:
"For the Australian Government to determine whether you are of good character, you might be asked to provide police certificates for each country you have lived in for 12 months or more, over the last 10 years, since turning 16 years of age."

Pag di ka raw makakuha ng police clearance, eto sabi:
"If a certificate cannot be obtained, or if a country is not listed on this page, please contact your nearest Australian Immigration overseas office for further information."
Also further info:
Non-Saudi citizens
Currently non-Saudi citizens are unable to obtain a police certificate from Saudi Arabia. However, you will need to provide the Department with a copy of your final exit document, and, if you were employed while in Saudi Arabia, a letter from your previous employer.
