Department of Home Affairs generally requires translations produced inside Australia to come from a NAATI-credentialled translator, while translations produced outside Australia must show the translator's full name, address, qualifications and experience. A NAATI Certified translation is the safest and most familiar option for case officers.

For an Australian visa lodgement, generally no — NAATI is Australia's own translation credential. If the same documents are also used by Thai authorities or a third country, separate Department of Consular Affairs legalisation may be required. NAATI certification and Thai MFA translation certification are not interchangeable.

Yes. High-resolution colour scans in which every stamp and signature is legible are sufficient for NAATI work. Originals are only needed when Thai MFA legalisation runs alongside the translation.

No. Visa decisions rest solely with the Department of Home Affairs. We are responsible for the accuracy and completeness of the translation, and we correct translator errors free of charge.
