You’re applying for an Australian visa, citizenship, a driver’s licence, a property purchase, or a court matter, and at some point in the form there’s a line that says: “documents not in English must be accompanied by a translation.” The question is suddenly practical and urgent: do you need a certified translation, what kind, and where do you get one without overpaying or missing a deadline?
This guide walks you through the decision in plain steps. By the end you will know whether you need a NAATI-certified translation, a non-certified translation, or no translation at all, and what to do next.
Quick answer: who needs a NAATI-certified translation?
You need a NAATI-certified translation if any of the following are true:
- You are submitting a non-English document to an Australian government body — the Department of Home Affairs (visa or citizenship), Services Australia, the Australian Taxation Office, a state transport authority for a driver’s licence, or any other Commonwealth, state or territory agency.
- You are submitting a non-English document to an Australian court, tribunal, or legal proceeding.
- You are submitting a non-English document to an Australian university or registered training organisation as part of an admissions or enrolment process.
- A receiving party (employer, insurer, regulator, professional registration body) has asked specifically for a “certified”, “NAATI-certified”, or “professionally certified” translation.
If none of those apply — for example, you just want to read a foreign document for personal understanding — you do not need a NAATI-certified translation, and a non-certified translation or even a free machine translation may be enough.
The decision tree, step by step
Step 1: Is the document in a language other than English?
If no, you do not need a translation at all. Skip the rest of this guide.
If yes, continue to Step 2.
Step 2: Who is going to read or rely on the document?
This is the most important question, because it determines whether the translation needs to be certified.
- An Australian government body, court, university, or regulator? → You need a NAATI-certified translation. Continue to Step 3.
- A US government body (USCIS, state DMV, IRS)? → You need a US-style certified translation, which is different from NAATI but follows similar rules. See our USCIS translation guides.
- A foreign government, embassy or consulate? → You usually need a translation certified to that country’s standard, which may require notarisation, an apostille, or sworn translator credentials. Check the receiving authority’s website first.
- An employer, landlord, bank, or other private party in Australia? → They will usually accept a NAATI-certified translation, but ask first — some will accept a non-certified translation if the source document is straightforward.
- You, personally, just want to understand the document? → A non-certified translation, or a free machine translation, is fine. Stop here.
Step 3: Is the document a “template” type or a “full” translation?
NAATI-certified translation pricing is determined by document type. Knowing which category yours falls into tells you what to expect.
- Template documents have a standardised structure across most countries: birth certificates, marriage certificates, divorce certificates, death certificates, police checks, driver’s licences, academic transcripts, single-page identity documents. These are translated using a standardised template at a flat per-document rate.
- Full translations are everything else: statutory declarations, contracts, medical reports, court documents, expert reports, free-form letters, and any document where the structure and content are unique. These are translated page by page at a flat per-page rate.
You do not need to figure this out yourself before uploading — the system tells you which category your document is in, and shows the price up front. See Affordable NAATI Translation for the full pricing model.
Step 4: How fast do you need it?
NAATI-certified translation through Immi Translating Service is the fastest option in Australia — same-day or next-day for most documents, and within an hour for many template documents. There is no urgent surcharge, because the AI-assisted workflow is fast by default.
- If your visa lodgement, court date, or settlement is more than a week away, the standard turnaround is comfortable.
- If you need it today or tomorrow, upload now — you’ll see the timing on the upload screen.
- If a competitor has charged you an “urgent” loading fee, you do not need to pay it.
Step 5: Is the document sensitive?
If the document contains medical information, legal evidence, financial records, or anything else that could harm you if leaked, the question of where the translation is processed matters.
- Free online translators and consumer chatbots typically process your text on offshore servers and may use it for training.
- Immi Translating Service processes documents on Australian onshore infrastructure (AWS Sydney) on a HIPAA-aligned stack with no training on your data, and certified by a NAATI-credentialed human translator before delivery.

Common scenarios — what most people actually need
Partner visa (Subclass 309 / 100 / 820 / 801)
You will typically need NAATI-certified translations of: your foreign-language birth certificate, marriage certificate (or evidence of relationship documents), police checks from every country you’ve lived in for 12+ months in the last 10 years, and any supporting evidence not in English (joint bank statements, lease agreements, statutory declarations from family).
Skilled visa (Subclass 189 / 190 / 491) and citizenship
NAATI-certified translations of: identity documents, qualifications and academic transcripts, employment references, and police checks. Skills-assessment bodies (such as Engineers Australia, ACS, or VETASSESS) also require NAATI-certified translations of professional credentials. If you are a software professional going through ACS, note that ACS uses AcudocX for member document translation — the same platform that powers Immi Translating Service.
Student visa (Subclass 500)
NAATI-certified translations of: academic transcripts, qualifications, identity documents, and any financial-capacity documents not in English (bank statements, sponsor declarations).
Driver’s licence conversion
NAATI-certified translation of your foreign driver’s licence is required by every state and territory transport authority before you can convert or use it. See our driver’s licence translation guides for state-specific rules.
Court, tribunal, or legal matter
Always NAATI-certified, often with the translator’s certification statement and credentials clearly visible. If the matter is contested, the receiving party’s lawyers may scrutinise the translation, so the credential trail matters.
USCIS / US visa or property purchase
You need a US-style certified translation, which is structurally different from NAATI. See our USCIS translation guides.
Personal understanding only
A free machine translation (Google Translate, DeepL) is fine. Do not pay for certified translation if no one official is going to read the document.
What “NAATI-certified” actually means
A NAATI-certified translation is one where the translator is credentialled by the National Accreditation Authority for Translators and Interpreters, the Australian standards body, and where the translation carries the translator’s certification stamp, statement, and credential number. Australian government bodies, courts, and universities accept these without question.
It does not mean “translated by NAATI” — NAATI is the credentialling body, not a translation service. It means translated and certified by an individual translator who holds NAATI credentials. Hundreds of NAATI-certified translators use the AcudocX platform that powers Immi Translating Service.

Frequently asked questions
Do I need a NAATI translation for the Department of Home Affairs?
Yes. Home Affairs requires that any non-English document submitted with a visa or citizenship application be accompanied by a translation by a translator credentialled by NAATI (or, for documents translated outside Australia, a qualified equivalent with credentials clearly stated).
Can I translate my own documents?
Yes — with the right process. AcudocX, the platform that powers Immi Translating Service, developed a world-first self-service workflow that lets you translate your own documents (with optional AI assistance), then have a NAATI-certified translator verify and certify the final output. The self-service path is the cheapest and fastest option, and the NAATI certification at the end is what makes it legally accepted by the Department of Home Affairs, courts, and other Australian authorities. If you’d prefer not to do any of the work yourself, our full-service NAATI translation does it all for you. See our full guide to translating your own documents for the details.
What if my document is partly in English?
Only the non-English portions need to be translated, but the translation must reproduce the document’s structure faithfully so the reader can match the original to the translation. Upload the full document and the translator will handle this.
Is a “certified translation” the same as a “NAATI-certified translation”?
In Australia, in practice, yes. “Certified” without further qualification almost always means NAATI-certified. In other countries (US, UK, EU) the equivalent uses a different credentialling system; if your document is for an overseas authority, check what they require specifically.
Do I need an apostille or notarisation as well?
Usually no, for Australian government use. Apostilles are typically required only when documents will be used overseas in countries that are party to the Hague Apostille Convention. The receiving authority will tell you if you need one in addition to the translation.
How long is a certified translation valid for?
The translation itself does not “expire”, but some receiving authorities require recently-issued source documents (e.g., police checks within the last 12 months). Re-translation is only needed if the source document is re-issued or amended.
Still not sure?
If you’ve worked through the decision tree and you’re still uncertain, the safest path is: upload the document, see the per-document or per-page price, and proceed only if it’s needed. There is no quote process, no commitment, and no charge until you confirm.
