What Is a Certified Translation in Australia?
Therefore, if you need a certified translation, you must hire a NAATI translator. Once the translator completes a translation, they attach a certification statement that includes:
- Their NAATI Certification number
- A declaration that says the translation is true and accurate
- Their signature and date of translation
- The language pair (source and target language)
The certification acts as a confirmation that a qualified professional, bound by the AUSIT Code of Ethics, has confirmed the accuracy of the translation. Certified translations are accepted by Australian government departments, courts, universities, and professional bodies that need official submissions.
What Is a Notarized Translation?
- Verify the identity
- Witness the signature of the translator
- Put their notarial seal and signature on the document
The notary public does not check or verify the quality of the translation, but they confirm that the person doing it is a translator, and they swear to the accuracy of their work under oath. The objective is to add legal weight to the document, thus making it acceptable for various purposes.
All notarized translations have these key components:
- The completely translated document
- The translator’s signed certificate statement
- Official seal and signature of the notary public
- A certificate confirming the authentication process
- Date and location of notarization
That helps you understand what each of these terms means and what you need to look for in each of them. The following section will answer the main question of the discussion: certified vs notarized translations in Australia.

When Do You Need a Certified Translation in Australia?
The Australian authorities ask for certified translations from individuals migrating to the country. The requirements include translating all foreign-language documents to English for official use. Document translations from a certified translator are necessary in these scenarios:
A. Immigration and Australian Visas
Any foreign document that is submitted to the Department of Home Affairs, like birth certificates, police checks, marriage certificates, passports, etc., needs translation. It is highly recommended that you avail professional translation services in Australia to get them done by a certified translator to avoid Home Affairs translation rejection.
B. Legal Proceedings
Certified translations for evidence, affidavits, witness statements, or contracts are necessary for presentation in Australian courts and in front of law enforcement bodies. Engaging a certified police report translation service ensures these official incident records are accurate and fully admissible in legal proceedings.
C. Healthcare Registration
For individuals from foreign countries applying for a medical role, the Australian Health Practitioner Regulation Agency (AHPRA) requires translated qualifications and identification to be certified by a certified translator using the proper NAATI translation format.
D. Education
The schools and universities in Australia need certified transcripts and degree certificates for assessing admission and credit transfers. The professional translation services can help translate these documents as per the Australian document translation requirements.
E. Official Corporate Filings
Certification of foreign business documents is a mandatory requirement set by the Australian Securities and Investment Commission (ASIC).
F. Government Identity
Individuals must provide certified translations for driver’s licence translations or for any Department of Home Affairs processes.
When Do You Need a Notarized Translation in Australia?
A. Overseas Use
In cases where you need to submit Australian documents to foreign authorities, like getting married abroad, buying property overseas, or applying for foreign visas, the receiving authorities might ask for a notary verification.
B. Foreign Documents within Australia
Specific legal or court proceedings, or certain statutory bodies, may ask for notarization of the translator’s affidavit. This extra step helps ensure your foreign evidence remains admissible in Australian courts without causing procedural delays.
C. Corporate or Regulatory Filings
The financial regulators, like the ASIC, or government bodies, need independent verification for overseas regulatory documents at times. In such cases, notarization is essential.
In a nutshell, you would only require a certified translation while presenting a translated document to an Australian government body, university, or employer. Notarised translation should only be needed if the receiving entity instructs you to get one.
Understanding certified translation vs notarized translation is important for all migrating to Australia. It is highly recommended that you hire a certified translator to ensure everything is accurate and gets accepted by the authorities.
That will help you understand the differences between certified and notarisede translations.

For instance, the USCIS (United States Citizenship and Immigration Services) might accept certified translations, but they prefer notarized versions of the documents. On the other hand, in Australia, the Department of Home Affairs accepts certified translations for visa and immigration applications.
C. International Business Transactions
The documents that are needed in international business dealings, such as contracts and financial statements, often need notarization to make them legally compliant across borders.
D. Academic Documents for Foreign Universities
Foreign universities often ask for notarised translations of the academic documents, like transcripts and academic records, to consider them authentic.
