Why Subclass 100 Applications Are Refused in 2026 and How to Fix the Gaps

A Subclass 100 refusal is rarely mysterious: the permanent stage asks you to re-prove things the temporary stage already tested, and a refusal follows when one of those proofs is missing, stale, or inconsistent. According to the Australian Department of Home Affairs Partner (Migrant) visa (Subclass 100) official page, if your visa is refused the Department will tell you why it was refused and whether you have a right to a review of the decision, and it will not refund the application fee. This article is general reference material only and is not personalised advice on your own case, so weigh any step you take against the current official guidance or a properly qualified adviser.

What does a Subclass 100 refusal letter actually tell you?

The decision is given in writing, and a refusal must state the reason for the refusal and whether you have a right to a review of that decision. That is the single most useful feature of a refusal: the reason is named rather than implied, which means you can map it back to a specific requirement and work out whether that requirement can now be met.

The same page confirms there is no fee refund when an application is refused. The money question and the evidence question are therefore separate — paying again does not by itself close whatever gap produced the first decision.

One preliminary check matters before you diagnose anything. If the Department granted you the permanent Partner visa (subclass 100) immediately after granting your temporary Partner visa (subclass 309), you do not have to provide further documents or do anything else. Where that did not happen, stage two requires you to provide further documents, and every gap below applies to you.

Which gaps most often break a permanent-stage partner case?

The permanent stage is less a fresh relationship test than a continuity test plus an update test. The requirements are concrete, and each one points to a document or fact that is either in your file or missing from it.

Relationship continuity. You must provide evidence that you continue to be the spouse or de facto partner of the same person who sponsored you for the temporary Partner visa.
Identity and accuracy. As a visa applicant you must prove your identity and provide true information with your application.
Character documentation. Police certificates that are missing, expired, or issued by the wrong authority.
Document form. Untranslated documents, or scans that cannot be read.
Timing and notification. Submitting stage-two documents too early, or failing to report a change in your situation.

Has your relationship evidence kept up with the file?

The requirement is to show you continue to be the spouse or de facto partner of the same sponsor. Two practical consequences follow from that. Evidence that satisfied the 309 stage can simply be too old by the time stage two is assessed, and a change in the relationship must be notified rather than left to surface on its own.

The official guidance is explicit about the first problem: partner applications can have long visa processing times, and you should update your documents and evidence of your relationship regularly through ImmiAccount. If you did not attach all required documents when you applied, attach them as soon as you can.

Fix: upload relationship documents and supporting evidence of the relationship that post-date your earlier material, and keep updating while the application is pending.

Is your identity evidence complete, and is your information accurate?

You must provide a copy of the pages of your most recent passport, and it must show your photo, personal details, signature, and the passport issue and expiry dates. Separately, you must prove your identity and provide true information.

The Department also notes that applications with all required information can be processed faster, which is a reason to treat completeness as part of the case rather than as admin.

Fix: if you made a mistake on the application, let the Department know as soon as you can. If you are unable to update the application in ImmiAccount, the official page directs you to the Partner Processing Enquiry Form.

Are your police certificates current and from the right authority?

This is the most mechanical refusal gap and the easiest to close, because the rules are stated precisely.

You usually need to provide a current Australian police certificate for the permanent stage if you did not attach one with your subclass 309 application.
The Department may ask you to provide a new Australian police certificate if your previous certificate has expired. For immigration purposes, police certificates are valid for 12 months from the issue date.
Only complete disclosure National Police Certificates issued by the Australian Federal Police are accepted. Standard disclosure certificates, and national police certificates issued by Australian state or territory police, are not accepted.
You also need an overseas police certificate from any country, including your home country, where you spent a total of 12 months or more since the grant of your 309 visa.

Suppose an applicant spent fourteen months in a third country after the 309 was granted and supplied only an Australian check — that stay is what triggers the overseas certificate, and its absence is a self-contained, fixable gap.

Fix: order an AFP complete-disclosure National Police Check, and then audit every country where you have spent 12 months or more in total since your 309 grant.

Are your documents in a form the Department can accept?

Formal defects look trivial and behave like substantive ones, because an unreadable or untranslated document proves nothing.

Have all documents translated into English, and provide both the original and the translated document.
Translators in Australia must be accredited by the National Accreditation Authority for Translators and Interpreters (NAATI). Translators outside Australia do not have to be accredited, but each translation must include their full name, address and telephone number, and their qualifications and experience in the language they are translating — in English.
Scan or photograph all documents in colour, clearly enough to read. If a document runs to more than one page, save it all as one file. Documents do not need to be certified.

Fix: re-upload any non-English document together with a compliant translation, and replace scans that are not legible.

Did you submit at the right time, and have you reported changes?

You are eligible for consideration for the permanent Partner visa two years after you applied for the temporary and permanent Partner visas. You can check the date you submitted your application in ImmiAccount, and you should not send stage-two documents before the two years have passed.

You must also tell the Department about things that change after you apply but before a decision: changes to your marital or de facto status, the birth of a child, any other changes relevant to your application, and a request to withdraw your application. Changes to contact details, address or passport details are reportable too.

Fix: confirm your lodgment date in ImmiAccount before uploading, and treat any change in status or contact details as a notification obligation rather than an optional update.

What if your relationship has ended?

A cessation is not automatically the end of the permanent application. The official page states you may need to complete the Notification of Relationship Cessation form in ImmiAccount, and that you might still be eligible for the permanent visa if your relationship ends or your partner dies. All information you provide is confidential.

Where domestic and family violence is involved, the page states the Department may be able to help and that you may still be eligible for the grant of your permanent visa, pointing to the family violence provisions.

Fix: notify the change through the correct channel, and where family violence is a factor, look to the family violence provisions rather than assuming the application is lost.

Should you seek a review or lodge again?

The decision letter is what settles whether review is even available to you, because it must state whether you have a right to a review of the decision. Where that right exists, the review tests the same requirements — so the choice between review and a fresh application turns mainly on whether the named gap is one you can now close with evidence you did not have before.

Two limits shape the decision either way. The application fee is not refunded on refusal. And there is a hard submission ceiling: you can attach up to 100 documents for each person on the application, the attachment limit cannot be increased, and if you reach it for one applicant you can attach further documents to other clients on the application.

Frequently Asked Questions

Does a Subclass 100 refusal letter have to explain the reason?

Yes. The Department of Home Affairs states that if your visa is refused it will tell you why the visa was refused and whether you have a right to a review of the decision. Because the reason is stated in writing, you can match it to a specific requirement and check whether that requirement can now be met.

Is the application fee refunded if my Subclass 100 is refused?

No. The official page states plainly that the application fee will not be refunded if the application is refused. The cost of a fresh application is therefore a separate question from whether the original gap has been closed.

Can I still be granted the permanent visa if my relationship has ended?

Possibly. The Department states you might still be eligible for the permanent visa if your relationship ends or your partner dies, and that all information you provide is confidential. You may need to complete the Notification of Relationship Cessation form in ImmiAccount. If you are experiencing domestic and family violence, you may still be eligible under the family violence provisions.

How long is an Australian police certificate valid for immigration purposes?

For immigration purposes, police certificates are valid for 12 months from the issue date. The Department may ask you to provide a new Australian police certificate if your previous certificate has expired. This is why a certificate that was current at the 309 stage often needs replacing at stage two.

Which Australian police certificates does the Department accept?

Only complete disclosure National Police Certificates issued by the Australian Federal Police are accepted. The Department does not accept standard disclosure certificates, nor national police certificates issued by Australian state or territory police. Certificates are obtained through the AFP's National Police Checks service.

Do I need police certificates from countries outside Australia?

Yes, in the circumstances the Department sets out: you need an overseas police certificate from any country, including your home country, where you spent a total of 12 months or more since the grant of your 309 visa. The relevant overseas offices are listed under the Department's offices outside Australia.

When can I submit documents for the permanent stage?

You are eligible for consideration for the permanent Partner visa two years after you applied for the temporary and permanent Partner visas. You can check your submission date in ImmiAccount and should not attach stage-two documents before the two years have passed. If you cannot upload documents, the official page directs you to the Partner Processing Enquiry Form.

What should I do if I made a mistake on my application?

Tell the Department as soon as you can. The official page treats a mistake as something to report promptly rather than wait out. If you are unable to update your application in ImmiAccount, you need to contact the Department using the Partner Processing Enquiry Form.
