Australian citizenship document translation by a NAATI-certified translator
Short answer
An Australian citizenship application must include identity and family documents that are not in English together with an English translation. For applicants inside Australia, the Department of Home Affairs requires translations by a NAATI-certified translator; translations made outside Australia must show the translator's full name, address, contact details and qualifications. The document workflow has five steps and translation itself normally takes 1–3 business days, excluding processing queues.

Documents usually translated
Birth certificate
Confirms date and place of birth and parents' names. The translation must reproduce the document number, every stamp and the registrar's signature block shown on the original.
House registration and ID card
Used for identity and address history. Where there have been several address changes, translate the pages covering the period the application relies on.
Marriage or divorce certificate
Explains family status and the relationship to any co-applicant. Registration numbers, registration dates and attached agreements must all appear in the translation.
Change of name record
Needed whenever older documents show a different name from the current passport. This set links every document to one person.
Overseas police certificate
Applicants who lived overseas for the relevant period may be asked for a police certificate from that country, translated in full including every stamp and endorsement.
Children's documents
Birth certificates and custody documents for children included in the application also need translating, with name spellings matching the passports and the parents' documents.
Step by step
1) Check the document list for your application type
Different citizenship pathways ask for different evidence. Open the Department of Home Affairs document list for your pathway and mark every item that is not in English.
2) Obtain fresh certified copies
Order recent copies of civil registration records so stamps and signatures are legible. Faded or skewed scans leave gaps in the translation that officers rely on when verifying identity.
3) Send colour scans for a quote
Send the files by LINE or email with the passport spelling of your name, the country you are applying from and your deadline, so the quote and timeline are agreed before work starts.
4) Translation and independent check
A NAATI-certified translator produces the translation with their stamp and CPN, then a reviewer compares every number, date and proper noun against the source document.
5) Assemble the bundle before uploading
Pair each original with its translation in one PDF, order them as ImmiAccount requests, and keep backups in case further evidence is requested.
Common mistakes
- • Translating only the first page of a house registration when the evidence sits on the person-record pages
- • Name spellings that differ from the current passport with no change-of-name record to link them
- • Submitting from inside Australia with a translation that carries no translator stamp or CPN
- • Translating outside Australia without stating the translator's address, contact details and qualifications
- • Leaving out stamps, signatures or endorsements printed on the back of the original
- • Uploading the translation alone instead of pairing it with the image of the original
- • Using an old certified copy whose stamps have faded, forcing the translation to mark text as illegible
Frequently asked questions
Does an Australian citizenship application always need a NAATI translation?
If you apply from inside Australia, the Department of Home Affairs requires documents that are not in English to be translated by a NAATI-certified translator. Translations produced outside Australia are accepted when they show the translator's full name, address, contact details and qualifications. Using a NAATI-certified translator wherever you are keeps one format valid for both situations.
Which documents are most often translated for citizenship?
The common set is the birth certificate, house registration, national ID card, marriage or divorce certificate and any change-of-name record, because they establish identity and family relationships. Applicants who lived in a third country may also need that country's police certificate. Each document is translated in full, not only the lines that look relevant.
Do documents need consular legalisation before translation?
For an application lodged directly with an Australian authority, a complete and accurate English translation is normally what is required, and consular legalisation is not automatically part of it. If another body in the same process asks for legalised documents, legalise the original first and translate the fully stamped version so the work is not repeated.
Do translations expire?
A translation has no expiry of its own, but the underlying document may. Police certificates in particular are often required to be recent. When you obtain a newer original, order a new translation as well, because the document number and issue date differ from the earlier copy.
My birth certificate spells my name differently from my passport. What now?
The translator transcribes the name as it appears on the source document and notes the passport spelling so an officer can match the two. If the difference comes from a legal name change, include the change-of-name record and its translation in the same bundle so the trail from the older documents to the current passport is visible.
Can I submit translations digitally?
Yes. ImmiAccount accepts uploads, so a PDF translation carrying the translator's stamp and CPN works normally. Upload the image of the original alongside its translation, either in one file or as consecutive files, and keep the high-resolution source files in case further evidence is requested.
How long does translation take?
A standard personal-document set usually takes 1–3 business days from the moment clear scans and the confirmed name spelling are received. Larger bundles or documents with long tables take longer. If you have a deadline, send it with the files so the timeline can be assessed before work begins.
Can I order from outside Australia?
Yes. The whole process runs online: send scans, confirm name spellings, review the draft and receive the stamped PDF. Printed copies can be posted to an overseas address when needed, provided the destination country and the date you need them are known in advance.
Do my children's documents need translating too?
Yes, when they are not issued in English, especially birth certificates showing parents' names and any custody documents where the parents live apart. Check that the parents' names on the children's documents match every other document in the bundle so the relationship is not questioned.
What if the department requests more documents after lodgement?
Read the request carefully to identify exactly which document and which period is wanted, then obtain a fresh original before ordering the translation. Documents already translated can be reused if they are the same copy. Send only what was requested, within the deadline given, and keep proof of what you submitted.
