The most direct check is to search the practitioner name and number in NAATI’s own Online Directory and match it against the stamp on the translation. For documents translated outside Australia, the Department of Home Affairs requires the translation to show the translator’s full name, address, contact number and qualifications or experience in English; translations produced in Australia must come from a NAATI-certified translator.
