Process at a glance

1. Submit the file and name the Australian receiving bodyApplicantClear scan + passport name spellingapprox. 1 day

3. Stamp, certification number and signature appliedNAATI-certified translatorFinished translationapprox. 1 working day

Durations are estimates and depend on the responsible authority's queue. Always confirm current requirements with the receiving body before filing.

Additional frequently asked questions

What if the name spelling differs from the passport?
The passport spelling governs. Where the source document spells it differently, the translator adds an explanatory note so the reviewing officer can link the records.
Does the translation expire?
The translation itself does not expire, but translator certification runs in renewal cycles and the receiving body may ask for a freshly issued source document, so confirm the rules before filing.
What is a NAATI-certified translation?
A translation produced by a translator certified by NAATI, Australia's National Accreditation Authority for Translators and Interpreters. Australian government bodies treat it as the standard for foreign-language documents filed with an application.
Which Australian bodies require it?
Most commonly the Department of Home Affairs, state road authorities such as VicRoads, universities and colleges, state registries of births, deaths and marriages, and professional skills-assessment bodies. Requirements vary by body.
Does a NAATI translation need further legalisation?
Australian bodies generally accept the certified translator's stamp without embassy involvement, though other legal proceedings may call for additional certification case by case.
Which languages and documents are covered?
Thai–English is the most requested pair, alongside other pairs with certified practitioners. Typical documents are birth certificates, house registration, marriage certificates, driving licences, transcripts and police clearance certificates. Scope and requirements are confirmed case by case by phone, LINE or email.

How this connects to the next step

Australian agencies accept only NAATI translations, yet originals such as powers of attorney still need Thai attorney notarial certification first; partner and skilled visa files usually run in parallel with a Thai police clearance certificate.

In depth: the real requirements and why documents get rejected — NAATI

Written from the competent authority's published rules, not marketing copy.

The documents most often handled under NAATI requirements are house registrations, birth certificates, marriage certificates, name-change records, academic transcripts, and police clearance certificates — each with its own points of scrutiny.

Conditions you actually have to clear

  • The language pair and direction must match the direction in which the practitioner is certified.
  • Every page and every element of the original must be covered, including pages that carry only a seal.
  • Most Australian authorities accept digitally signed translations, though some matters still call for a printed set.

Common causes of rejection

  • A translation prepared before, but signed after, the practitioner's certification expiry date.
  • Translating only the pages containing text and omitting seal-only or numbered blank pages.

Where a visa or registration deadline applies, allow time for the possibility that the assessor requests additional documents, rather than budgeting only for translation time.

Practitioner guidance — NAATI certified translation

Competent authority: NAATI — National Accreditation Authority for Translators and Interpreters, Australia

Practitioner guidance

  • Turnaround is approximately 5–7 working days depending on page count and language pair — confirm before fixing a lodgement date.
  • Documents filed with Australian authorities must be translated by a NAATI-certified translator, with the NAATI stamp and CPN visible on the translation.
  • NAATI translations do not require MFA or embassy legalisation unless the receiving body specifically asks for it.
  • Always submit the translation together with the source copy the translator worked from; assessors compare both.
  • Verify that the CPN printed on the translation is searchable in NAATI's verification system.

Pitfalls — why documents get rejected

  • A translation without a NAATI stamp or without a verifiable CPN.
  • Submitting the translation without the source copy it references.
  • Name spelling differing from the passport used in the visa application.
  • Reusing an old translation whose source document was later amended or reissued.
  • An incomplete relationship-evidence set, triggering a request for further information.

In-depth questions and answers — NAATI certified translation

Answers follow the competent authority's published requirements, not marketing copy.

Which authority is competent for NAATI certified translation?

NAATI — National Accreditation Authority for Translators and Interpreters, Australia is the principal competent authority for NAATI certified translation. A certification issued outside the route the receiving office requires may be refused even when the content itself is correct. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Where can the current requirements for NAATI certified translation be verified?

Check the notices published by NAATI — National Accreditation Authority for Translators and Interpreters, Australia. The official sources used on this page are https://www.naati.com.au/ · https://immi.homeaffairs.gov.au/. Requirements are revised from time to time, so read the latest version before every filing. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

What if our NAATI certified translation case has unusual conditions?

For edge cases — mismatched names across documents, foreign-issued records, or a tight deadline — have the set reviewed first, then reconfirm the conditions with NAATI — National Accreditation Authority for Translators and Interpreters, Australia. Ask our staff by phone, LINE or email for scope and timing (we do not publish fees on the page because they depend on the document type and destination). This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How long does NAATI certified translation take?

Turnaround is not fixed: it depends on the queue and rules of NAATI — National Accreditation Authority for Translators and Interpreters, Australia, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Does the result of NAATI certified translation expire?

Validity is set by the receiving office, not by the service provider. Many offices accept only recently issued documents, so confirm the destination's window first and only then start the process with NAATI — National Accreditation Authority for Translators and Interpreters, Australia, to avoid the document expiring while it waits in the queue. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Must the applicant appear in person for NAATI certified translation, or can it be delegated?

Some steps require the document owner to sign or appear; others accept a power of attorney. It depends on the rules of NAATI — National Accreditation Authority for Translators and Interpreters, Australia and on the document type, so confirm before booking an appointment rather than travelling and being turned away. Our staff can clarify by phone, LINE or email. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Why is no price shown for NAATI certified translation on this page?

Scope varies widely per case — page count, languages, number of certification rounds, and the official fees charged by NAATI — National Accreditation Authority for Translators and Interpreters, Australia under its published schedule. A single headline figure would be misleading, so we quote against the actual documents. Send the details by phone, LINE or email for an assessment matched to your case. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How should documents for NAATI certified translation be prepared to pass on the first submission?

Documents filed with Australian authorities must be translated by a NAATI-certified translator, with the NAATI stamp and CPN visible on the translation. The competent authority is NAATI — National Accreditation Authority for Translators and Interpreters, Australia. This is general guidance; requirements and processing times change — verify with the competent authority before filing.
