What Happens to My Subclass 300 Visa If the Relationship Ends in 2026?
If your relationship ends while you hold a Prospective Marriage visa (Subclass 300), the visa does not switch off by itself — it was granted for 9 to 15 months from the date of grant — and depending on your situation you may need to report the change. According to the Australian Department of Home Affairs' Prospective Marriage visa (Subclass 300) official page (as of the July 2026 official page), what a separation triggers is a notification step, not an automatic end: depending on your situation you may need to complete the Notification of Relationship Cessation form in ImmiAccount. This is general information only and not personalised advice about your own case, so your circumstances should be checked against the official pages and, if you need guidance fitted to your situation, a qualified professional.
Does my subclass 300 visa become invalid the moment we separate?
The Department's guidance does not describe separation as an automatic cancellation. The visa has its own lifespan: you can stay in Australia for 9 to 15 months from the date of visa grant, and the official page points you to your grant letter or VEVO to see exactly when your visa expires. What the guidance attaches to a breakup is a possible notification step, rather than a rule saying the visa evaporates the day you stop being a couple.
That distinction matters in practice. The date governing how long you can remain is still the one on your grant, not the day the relationship ended. A separate caveat on the official page applies to travel: you can travel to Australia after the first entry arrival date in your grant letter has passed if your visa is still valid, but your visa may still be subject to cancellation before arrival or at the border.
What exactly am I required to notify, and where does it go?
The notification the Department names here is the Notification of Relationship Cessation form in ImmiAccount. The official page frames it as something you may need to complete depending on your situation, and directs holders to the "Your relationship has changed" guidance to confirm whether it applies to them. If you cannot get into ImmiAccount, the Partner Processing Enquiry Form is the listed alternative way to notify.
This sits alongside the other change-of-details duties that come with holding the visa. Contact details, address and passport changes each have their own channel, and the birth of a child is likewise a change you must report.
If I'm no longer going to marry, does that end my path to a Partner visa?
The Subclass 300 is built around a plan: marry your prospective spouse, then move to the Partner visa (subclasses 820 and 801) after the marriage and before the 300 expires, because applying before the 300 ends means you pay less. Once the relationship has ended, that marriage-based step is no longer the route you were on.
That does not close the door. The Department states you may still be eligible for the Partner visa (subclasses 820 and 801) if your relationship ends or your partner dies, and it stresses that all information you provide is confidential. One hard condition is attached: you must be in Australia to apply for the Partner visa (subclasses 820 and 801).
What if the relationship ended because of domestic or family violence?
The official page addresses this directly. If you are experiencing domestic and family violence, the Department may be able to help, and you may still be eligible for the grant of your temporary and permanent visa. The detail sits in the Department's family violence provisions material, and the same confidentiality assurance covers what you provide.
The page also treats online safety as part of this scenario, which reflects how much of the communication runs through your own accounts. It recommends changing your ImmiAccount password as soon as possible, not using saved passwords to access ImmiAccount, and changing your email password or setting up a new email account. The eSafety Commissioner's online safety checklist is cited as a planning tool.
Should I switch to a different visa instead of riding out the 300?
There is a cost to switching that is easy to miss. As a Subclass 300 holder you are eligible to pay a lower visa application charge for a Partner visa (subclasses 820 and 801) application — but if you are granted any other visa, that new visa replaces your 300, and you may then need to pay the higher charge when you apply for the Partner visa.
Against that, the 300 still carries real permissions while it runs: full work rights protected by Australian workplace law, the ability to study (though without government support and at your own expense), and travel to and from Australia as many times as you want while the visa is valid. The remaining portion of your 9 to 15 months is therefore a window with both value and a deadline attached — check where you are in it using your grant letter or VEVO.
How do I confirm my visa is still valid today?
Use VEVO. Australian visas are digital and linked to your passport rather than stamped in it, and your visa number is contained in your visa grant letter. Airlines, Australian government agencies, and employers, banks or other registered organisations all check that digital record. If VEVO shows the visa as in effect, it is in effect — subject to you continuing to meet its conditions and obey Australian laws.
Visa settings and the Department's published procedures change over time, and the above reflects the official page as of July 2026, so the Department's current published guidance remains the authority.
Frequently Asked Questions
Does my subclass 300 visa get cancelled automatically when we break up?
The Department's guidance for people already holding this visa does not describe separation as an automatic cancellation — it describes a notification step. Your visa's validity of 9 to 15 months from the date of grant is what governs how long you can stay. Check the exact expiry date in your grant letter or through VEVO.
Do I have to tell the Department if the relationship ends?
Depending on your situation, you may need to complete the Notification of Relationship Cessation form in ImmiAccount, and the official page points to the "Your relationship has changed" guidance to confirm. If you have no access to ImmiAccount, the Partner Processing Enquiry Form is the listed alternative. Reporting the change keeps any later assessment based on accurate facts.
Can I still apply for a Partner visa (subclass 820/801) after the relationship ends?
The Department states you may still be eligible for the Partner visa (subclasses 820 and 801) if your relationship ends or your partner dies, and that all information you provide is confidential. The condition attached is that you must be in Australia to apply.
What if the relationship ended because of domestic or family violence?
The official page says the Department may be able to help and that you may still be eligible for the grant of your temporary and permanent visa under the family violence provisions. It also recommends changing your ImmiAccount and email passwords as soon as possible and points to the eSafety Commissioner's online safety checklist.
Is the information I give the Department kept confidential?
Yes. In the context of a relationship ending, including where a partner has died, the Department states that all information you provide is confidential. This covers what you submit about the relationship as well as material provided under the family violence provisions.
Will moving to another visa affect what I pay later for a Partner visa?
Potentially yes. As a Subclass 300 holder you are eligible for a lower visa application charge for the Partner visa (subclasses 820 and 801), but being granted any other visa replaces your 300 and may mean paying the higher charge later.
How long can I stay in Australia after the relationship ends?
The Subclass 300 allows you to stay for 9 to 15 months from the date of visa grant, and the official page points to your grant letter or VEVO for the exact expiry. Travel to and from Australia is allowed as many times as you want while the visa is valid.
