Do Subclass 300 Documents Need to Be Certified or Translated in 2026?
No. According to the Australian Department of Home Affairs' official page for the Prospective Marriage visa (Subclass 300), as of July 2026, you do not need to have any documents certified. Three rules still apply to the paperwork you upload: everything not already in English must be translated, every page must be scanned or photographed in colour, and the images must be clear enough to read. Skipping any of them is what tends to slow an application down, because a case officer who cannot make out a document or read its contents will simply come back for it.
This article is general information, not advice tailored to any one application; where your circumstances are unusual, treat the current official guidance and a qualified professional's view as authoritative rather than anything written here.
Do any documents need to be certified?
No. The Department's document-preparation instructions state plainly that no documents need to be certified for this visa. You can drop the habit — there is no step in which a justice of the peace, notary, or similar signs off on your copies before you upload them.
What replaces certification is legibility. Scans and photographs must be clear enough to read, so the quality of the file matters more than any stamp that might have gone on it.
Which documents must be translated into English?
Any document that is not in English has to be translated, and you provide both versions: the original and the translated document go into the application together. This applies across the board, not just to court or registry documents.
That scope matters once you look at what a subclass 300 application actually asks for. Identity documents include:
- A birth certificate showing the names of both parents. If you cannot get one, the alternatives are the identification pages of a family book showing both parents' names, of a government-issued identification document, of a court-issued identity document, or of a family census register.
- Your current passport pages showing your photo, personal details, and issue and expiry dates.
- A national identity card, if you have one.
- Proof of a name change, if applicable — a marriage or divorce certificate, change-of-name documents from an Australian Registry of Births, Deaths and Marriages or the relevant overseas authority, or documents showing other names you have been known by.
Evidence of relationships is attached too — your relationship with your prospective spouse, any former relationships, and any dependants you have. For many applicants, several of those items will be issued in a language other than English, which is precisely why the translation rule matters more than certification does.
Who is allowed to translate the documents?
The requirement depends on where the translator is, not where you are.
| Translator location | What the guidance requires |
|---|---|
| In Australia | Must be accredited by the National Accreditation Authority for Translators and Interpreters (NAATI) |
| Outside Australia | No accreditation needed, but each translation must carry the translator's full name, address and telephone number, and their qualifications and experience in the language they are translating |
The details required from overseas translators must themselves be in English. In practice, this means a translation package from abroad is not just the translated text — it needs the translator's identifying details and credentials attached on each translation.
How do the colour scanning rules work?
All documents — English and non-English alike — must be scanned or photographed in colour. Colour is not a formality here: stamps, seals, security backgrounds and photo pages are what tend to disappear or flatten in greyscale, and those are exactly the elements a decision-maker is checking.
Two handling details follow from this:
- Readability is the standard. Blurry, skewed, cropped or glare-washed images fail even though they technically exist in the file.
- Multi-page documents become one file. If a document runs to several pages, save them all as a single file rather than uploading page by page.
Combining this with the translation rule gives the practical workflow: keep the original colour scan, keep the translation, merge pages where they belong to one document, then upload once.
How many documents can you attach, and should anything be uploaded twice?
You can attach up to 100 documents for each person on the application, and the limit cannot be increased. If you reach the limit for one applicant, further documents can be attached to other clients on the same application.
Because the ceiling is real, two habits protect you:
- Label clearly. The Department advises labelling your documents clearly so it is obvious what each file is.
- Attach each document once, even when you are relying on it to show more than one thing. Re-uploading the same passport or birth certificate in two places burns slots without adding evidence.
Assume two applicants each need the identity set plus relationship evidence: merging multi-page documents into single files and avoiding duplicate uploads is usually enough to stay well inside 100 per person. Reaching the limit generally signals duplication rather than genuinely excessive evidence.
Where does this fit in the rest of the application?
The application is lodged online, through ImmiAccount, and you must be outside Australia when you apply. Documents are attached to the completed application; the checklist in ImmiAccount is designed to help you confirm everything required is included, and applications that arrive complete tend to move faster.
Separate from the document-preparation rules, other evidence runs on its own clocks: police certificates are valid for 12 months from the issue date (and where an Australian Federal Police National Police Certificate is more than 15 months old, new checks will be required), and health assessment results are valid for 12 months from when the examinations were completed. Those validity periods are not affected by whether a document was translated or scanned in colour.
Frequently Asked Questions
Do Subclass 300 documents need to be certified copies?
No. As of July 2026, the Department of Home Affairs states you do not need to have any documents certified for this visa. There is no requirement to have copies signed off before uploading them.
Which documents must be translated into English?
Every document that is not already in English. You provide both the original and the translated version in your application, rather than the translation alone.
Do translators outside Australia need NAATI accreditation?
No. Accreditation by NAATI is required only for translators in Australia. Overseas translators must instead include their full name, address and telephone number, plus their qualifications and experience in the language translated, written in English.
Can I upload black-and-white scans if they are still readable?
No — all documents, whether English or not, must be scanned or photographed in colour. The images must also be clear enough to read, so quality counts as much as the colour setting itself.
Should I attach the same document twice if it proves two different things?
No. Label your documents clearly and attach each one once, even when it supports more than one point. This also helps you stay within the limit of 100 documents per person, which cannot be increased.
What if a document has multiple pages?
Save every page of that document as one file. Uploading pages as separate attachments wastes your attachment allowance and makes the file harder to follow.
