Building a Decision-Ready File: Police Certificate Validity and Translation Rules (2026)

A police certificate will be accepted only if it was issued in the 12 months before you apply, and every non-English document in the file needs an English translation backed by the credentials the department requires. According to the Australian Department of Home Affairs' official "Check twice, submit once" page (as at October 2026), applicants should also check their ImmiAccount inbox regularly and respond quickly to any request for more information, because processing is delayed whenever the department has to wait.

For anyone assembling a file to a professional standard, those three control points — the age of the police certificate, whether each translation can be verified, and how quickly a request is answered — are where an otherwise complete application most often stops being decision ready. What follows describes that standard in general terms and is not personalised professional advice; confirm the requirements against the official pages referenced at the end of this article, or with a qualified professional, before relying on them for your own circumstances.

How recent does a police certificate have to be?

The guidance is to get your police certificates before you apply, and the department states that it accepts police certificates issued in the 12 months before you apply for your visa. The test is measured against the date you lodge, not the date a decision is made.

Because the guidance refers to police certificates in the plural, the sensible reading is that the same 12-month test applies to each certificate you rely on, not only the one from the country where you currently live. A file containing an up-to-date certificate from one country alongside an older certificate from another is not internally consistent, and internal consistency is essentially what "decision ready" describes.

The timing trap is easy to fall into. Assume an applicant obtains a police certificate in the first month of preparation, then spends a long period assembling everything else; by the time the application is lodged, that certificate may sit at the edge of the 12-month window or outside it, and the document has to be obtained again. Ordering police checks early only helps if lodgement follows within the window.

What credential must a translation carry?

All non-English documents must be translated into English. What must accompany the translation depends on where the translation is arranged — the distinction concerns how the translator's credentials are evidenced, not whether a translation is needed at all.

Where the translation is arranged	What must accompany the English translation
In Australia	The translator's NAATI practitioner number
Outside Australia	The translator's full name, address, phone number, and their qualifications in the language they are translating

NAATI is the National Accreditation Authority for Translators and Interpreters, the accreditation body the department names for translations prepared inside Australia. Outside Australia there is no NAATI number to provide, so the file instead has to identify the person who did the work and show that they are qualified in the language pair involved.

This bears directly on police certificates. A certificate issued in a language other than English is a non-English document like any other: it needs an English translation, and that translation needs the credential matching where it was prepared. In practice the police certificate is one of the documents most often lodged with a translation that cannot be verified, because applicants treat the certificate itself as the evidence and the translation as an afterthought.

Where do file inconsistencies usually start?

Identity details are the joinery of a file — they are what makes separate documents describe the same person. The department asks applicants to check that their name is spelt correctly and matches the passport being used to apply, to watch for autocorrect, and to list all names they have been known by.

From a quality standpoint this is a mechanical check rather than a judgement call: the name on each document should be compared against the passport character by character, including ordering, spacing and any name previously used. A mismatch rarely means the underlying document is wrong; it usually means the file has failed to explain why the same person appears under two forms of name, and listing every name known by is how that gap is closed.

There is one extra pack for minors. If an applicant is under 18, the department requires a copy of the applicant's passport, the applicant's birth certificate, and each parent's passport.

How should ImmiAccount be handled after lodgement?

Lodging a complete file does not end the applicant's obligations. The department directs applicants to check their ImmiAccount inbox regularly for updates and requests for more information, and to respond quickly when information is asked for — in its own words, processing is delayed if it has to wait. Where an applicant does not have what has been requested, the instruction is to say so and explain why, rather than leave the request unanswered.

The same logic applies to biometrics: once the department requests biometric data, it should be collected quickly. On travel, the department's suggestion is to submit the application well ahead of the intended travel date and to book flights only after the visa is granted.

ImmiAccount is the channel through which all of this happens, and most Australian visas must be applied for online through it. When the account is created, the applicant should choose to receive electronic communication, because that is how application updates are delivered. Within the account an applicant can:

track the progress of the application
see requests for more information
add more information or documents
update contact details

A file that cannot be reached is a file that cannot be processed, so keeping contact details current is part of the quality standard rather than an administrative footnote.

How do you confirm the exact document list for your visa?

The police certificate and translation rules above apply broadly, but the document list itself is set by the visa subclass. The department's route to that list runs through its own website:

Go to the Department of Home Affairs website.
Enter the visa subclass you are applying for into the search bar — the subclass is the number that sits alongside the visa name, such as Visitor (subclass 600).
Select the web page for that visa subclass.
Click the "step by step" tab.
Go to "gather your documents", click "show steps", and click through the "see how" options.

Health is usually part of the same list. For most visa applications a health check is needed, and the department notes that it may be possible to complete one before applying, using the My Health Declarations service, which is reached through its "when to have health examinations" guidance. Because a health check and a police certificate each carry their own timing considerations, reading the "gather your documents" steps before ordering either one is what keeps the file synchronised.

Frequently Asked Questions

How long is a police certificate valid for an Australian visa application?

The department accepts police certificates issued in the 12 months before you apply for your visa. The test runs from the date you apply, so a certificate obtained long before lodgement can fall outside the window. The guidance is to get police certificates before you apply.

Does a police certificate issued in another language need to be translated?

Yes. All non-English documents must be translated into English, and a police certificate is not an exception. The translation must carry the credential that corresponds to where it was prepared.

What is a NAATI practitioner number, and when is it required?

NAATI is the National Accreditation Authority for Translators and Interpreters, the body the department names for translations prepared in Australia. If the translation is arranged while you are in Australia, the translator's NAATI practitioner number must be included with it.

What must be included with a translation prepared outside Australia?

Outside Australia, the file must carry the translator's full name, their address, their phone number, and their qualifications in the language they are translating. These details stand in place of the NAATI number, which applies to translations arranged inside Australia.

How often should I check ImmiAccount after lodging?

The department asks applicants to check their ImmiAccount inbox regularly for updates and requests for more information. Requests should be answered quickly, because processing is delayed whenever the department has to wait. If you do not have what is asked for, say so and explain why.

Can I book flights before my visa is granted?

The department suggests booking flights only after the visa is granted. It also advises submitting the application well ahead of when you want to travel.

What extra documents are required if the applicant is under 18?

An applicant under 18 must submit a copy of their own passport, their birth certificate, and the passport of each parent. These sit alongside whatever else the visa being applied for requires.
