Subclass 300 Relationship Ends or Wedding Is Cancelled: What Happens to the Fiancé Visa?

If the relationship behind a Subclass 300 Prospective Marriage Visa ends, the applicant should not simply continue as though nothing has changed. The Subclass 300 is based on the intention to marry the sponsoring prospective spouse before the visa period ends, and Home Affairs requires relationship changes to be notified.

What if the 300 application is still pending?

If the engagement ends before Home Affairs decides the Subclass 300 application, the applicant may no longer satisfy the core requirement to intend to marry that prospective spouse. The Department should be told about the change. The sponsor can also withdraw the sponsorship, although Home Affairs—not the sponsor—makes the visa decision.

What if the Subclass 300 has already been granted?

A relationship ending after grant does not create a right to use the 300 with a different fiancé. The original visa was granted in connection with the sponsoring prospective spouse. Notify Home Affairs of the relationship change and obtain advice about the applicant’s current visa status and any other lawful options.

Can you change to a new sponsor?

There is no general rule allowing a Subclass 300 holder to simply substitute a new fiancé into the old Prospective Marriage Visa. A later relationship may require a different visa strategy and fresh eligibility assessment.

What if the wedding is postponed but the relationship is still together?

That is different from relationship breakdown. If the couple remains committed but the original ceremony is cancelled, the practical priority is to ensure a legally valid marriage can occur before the 300 expires if they intend to use the normal 300 → 820/801 pathway.

Family violence is different

Family violence provisions now extend to certain current or former Subclass 300 holders. Home Affairs states that a 300 applicant or holder may be eligible for the permanent Partner Visa pathway where the relationship ends because of family violence and the specific statutory requirements are met. For the 300 pathway, location in Australia and, in some cases, the person’s current substantive-visa status and an 820/801 application are important.

See our Partner Visa family violence provisions hub for the specialist rules.

Case example

A Subclass 300 holder entered Australia and the engagement ended before the planned wedding. The applicant initially believed the visa could be used to marry a new partner. The legal review instead separated three issues: notifying Home Affairs of the ended relationship, checking the current 300 status and expiry, and assessing whether any separate visa pathway was available. The original sponsor was not simply replaced inside the existing 300.

Home Affairs provides relationship-change instructions through its relationship ended guidance. For the ordinary fiancé pathway, see our Subclass 300 hub.
