Thai documents for use in Australia: apostille versus NAATI-certified translation
In short
The two answer different questions. An apostille certifies that the signature and seal on the original document are genuine. A NAATI-certified translation states that the translation corresponds to the original. Most Australian authorities set the translation requirement, and will say so explicitly if they also want the original certified.
Read the requirement from the body processing your case
Requirements come from the receiving body — the immigration authority, a university, a skills assessing authority, or a professional council — not from the translator. Keep the requirement in writing and share it with our team before work begins.
The safest order of operations
Obtain a current original, confirm whether the original needs certification, translate the full document to the required standard, check name spelling against the passport, then lodge the complete set together. Doing these out of order usually means re-translating.
Planning for time
Processing times at Thai and Australian authorities vary through the year. Allow buffer time and check the latest announcements before setting a lodgement date. Our team can review the completeness of your set over LINE or by phone.
