The Australian Certificate of Identity (COI) is a biometric travel document issued by the Department of Foreign Affairs and Trade to individuals who are not Australian citizens and are about to leave Australia or one of its territories.
It should not be confused with the Document of Identity, which conversely is intended mainly for use by Australian citizens in circumstances where it would be unnecessary or undesirable to issue a passport.
