The Complete 2026 Guide: Avoid Delays, Refusals and Costly Mistakes

If you are applying for an Australian visa, there is a good chance you will need to submit documents that were not written in English. And if those documents are not translated correctly, by the right kind of translator, your application could be delayed, queried, or refused outright.

So what exactly counts as the right kind of translator? In Australia, that means a NAATI certified translator. Here is everything you need to know, laid out clearly so you can get it right the first time. If you are ready to get started, you can order your translation online or request a free quote at any point.

What Is a NAATI Certified Translator?

NAATI (the National Accreditation Authority for Translators and Interpreters) is the only body in Australia that certifies translators and interpreters to a government-recognised standard.

When the Department of Home Affairs requires a certified translation, they mean a translation completed or reviewed and endorsed by a NAATI credentialled professional. The translation must include the translator’s full name, their NAATI credential number, a signature, and the date of certification.

Which Documents Need NAATI Certified Translation?

The Department of Home Affairs requires certified translations for all documents that are not in English. Below is a breakdown by document category, with notes on where each applies to specific visa types.

1. Identity and Personal Documents

• Birth certificate (yours, your partner’s, or your children’s)
• Passport pages (bio pages, entry and exit stamps where required)
• National ID cards
• Deed poll or name change documents
• Death certificates (for deceased family members)

2. Relationship and Family Documents

These are especially critical for partner visa applications (subclass 820/801 and 309/100):

• Marriage certificate
• Divorce decree or annulment documents
• De facto relationship declarations
• Adoption papers
• Custody or parental responsibility orders

3. Academic Qualifications and Education Records

• University or college degrees and transcripts
• Secondary school certificates
• Trade qualifications and vocational credentials
• Student enrolment or graduation letters

These are required for skilled migration visas (subclass 189, 190, 491) and student visa applications (subclass 500). They are also used in skills assessments through bodies like Engineers Australia, VETASSESS, and the Australian Computer Society. See our NAATI certified translation services for a full list of document types we cover.

4. Employment and Work History Documents

• Employment reference letters
• Pay slips and salary certificates
• Statutory employment declarations
• Tax documents from overseas

5. Financial Documents

• Bank statements
• Property ownership documents
• Loan or mortgage statements
• Proof of assets for parent or investor visa applications

6. Police Clearances and Legal Records

• Police clearance certificates from any country where you have lived for 12 or more months
• Court records or legal declarations
• Character declarations

Police checks must be from the issuing country’s authorities and are a mandatory requirement for most visa subclasses, including skilled, partner, employer-sponsored, and parent visas.

7. Medical and Health Documents

• Medical reports or hospital records (if required as supporting evidence)
• Vaccination records
• Mental health or specialist assessments

8. Business and Sponsorship Documents

• Business registration certificates
• Company financial statements
• Sponsorship agreements
• Business activity statements from overseas

These are particularly relevant for Business Innovation and Investment visas (subclass 188/888) and Employer Nomination Scheme visas (subclass 186).

Do All Non-English Documents Need to Be Certified?

Yes, as a general rule. The Department of Home Affairs states that all documents not in English must be accompanied by an English translation prepared by an accredited translator. There is no official exemption for simple or short documents.

Some applicants mistakenly believe that a bilingual friend, a Google Translate printout, or an unaccredited translator will suffice. These are not accepted and could result in your application being put on hold or refused.

NAATI Certified vs. Notarised: What Is the Difference?

This is one of the most common points of confusion for visa applicants.

NAATI Certified: The translation was completed or endorsed by a credentialled NAATI translator. This is what Australian immigration requires.

Notarised: A notary public (usually a lawyer) has verified the authenticity of a signature or document. This is not the same as a certified translation and is not a substitute for it.

In some cases you may need both, for example a notarised original document plus a NAATI certified translation of that document. But the two requirements should never be confused.

How Long Does NAATI Certified Translation Take?

Turnaround time varies depending on the language pair and the complexity of the documents. Standard timeframes are:

• Standard (3 to 5 business days) for most common documents
• Express (24 to 48 hours) available for urgent applications — see our translation services
• Same-day available in some cases, confirm with our team directly

• Verifiable NAATI credential numbers on all translated documents
• Experience with Australian immigration documents specifically
• A clear quality assurance process
• Transparent pricing with no hidden fees
• Secure handling of sensitive personal documents

Frequently Asked Questions

Can I get a NAATI certified translation if my language is rare or uncommon?

Yes. NAATI credentialled translators exist for over 100 language pairs. Aussie Translations covers a broad range of languages. Check our full languages list to see if yours is covered, or contact us directly.

What if I already have a translation from my home country?

Overseas translations are generally not accepted by the Department of Home Affairs unless they have been certified by a NAATI credentialled translator in Australia. You will typically need to have the documents re-translated or certified locally.

Does the translation have to be done in Australia?

No, but the translator must hold a valid NAATI credential. Some NAATI credentialled translators work remotely. What matters is the credential, not the location.

How much does NAATI certified translation cost?

Costs vary depending on the language pair, document type, and turnaround time. For a personalised, transparent quote, contact Aussie Translations directly or use our online ordering system for an instant price.
