Accreditation
A regular translator can be anyone who speaks two languages — a bilingual friend, an online platform, a general translation agency. A NAATI-certified translator has been formally accredited by Australia's National Accreditation Authority for Translators and Interpreters, having passed rigorous testing on linguistic ability, terminology and professional ethics.
Accountability
NAATI-certified translators are bound by NAATI's Code of Ethics and are professionally accountable for their work. Every translation carries a signed statement, the translator's stamp and unique certification number. A regular translation carries none of this — there is no formal recourse if the translation is wrong.
Legal and government acceptance
This is the practical difference that matters most. The Department of Home Affairs, VicRoads, TfNSW, Service SA, every Australian university, and every court and tribunal require NAATI-certified translations. Regular translations — no matter how accurate — will be rejected on submission.
What the certification statement says
Every NAATI-certified translation includes a certification statement to the effect of: "I certify that the attached is a true and accurate translation of the original document, prepared by a NAATI-certified translator." The statement is signed and dated, and includes the translator's certification number, so the receiving agency can verify credentials.
What qualifies a NAATI translator
NAATI certification is not automatic — translators must pass a formal test administered by NAATI, meet continuing professional development requirements, and renew their certification every three years. Trans Lingo works exclusively with translators whose certification is current and specifically covers Spanish to English document translation.
Cost difference
NAATI-certified translation is not dramatically more expensive than general translation. Trans Lingo prices standard Spanish to English documents at $59 per page — often less than a general agency charges for uncertified work, and a fraction of what a visa refusal or delay would cost.
The risk of using non-certified translation
Beyond outright rejection, using non-certified translation for an official document creates hidden risks: incorrect terminology, mismatched names or dates, and missing document elements (stamps, seals, signatures) that a case officer expects to see. All of these can lead to further evidence requests, refusals, or delays. See what happens if your translation is rejected for more.
The bottom line
If a document is being submitted to any Australian government agency, court, or educational institution, it must be NAATI-certified translated. Regular translation is fine for personal understanding, but has no standing for official use.
