Thai → English translation for Australian authorities
Thai civil registry documents submitted to Australian authorities must be accompanied by an English translation. Translations produced inside Australia must come from a NAATI certified translator; translations produced outside Australia must show the translator's full name, address, contact details and qualifications on the translation itself.

Names, script and dates

- Titles and military or police ranks are translated and retained, never dropped.
- Thai documents use the Buddhist Era; dates are converted to the Gregorian calendar and the conversion is noted.
- Garuda emblems, seals and signatures present on the original are described in the translation rather than left out.
Why translations in this pair get sent back
- Name spelling that differs from the passport, so the authority treats the applicant as a different person.
- Sending only the first page of the house registration without the personal record page.
- Skewed scans with cropped edges that hide document numbers or seals.
- Reusing an old translation after the underlying record has changed.
Frequently asked questions
Do Thai documents need consular legalisation before translation?
It depends on the receiving body. Most Department of Home Affairs visa applications only require a correctly prepared translation together with a copy of the original. Marriage registration in Australia or court filings may additionally ask for documents legalised by the Thai Department of Consular Affairs, so check the receiving body's requirements first.
Can one translation be used for several applications?
Usually yes, as long as the underlying document has not changed and the receiving body does not set its own validity period for translations.
