Prospective Marriage Visa Application Help: Subclass 300

When does the subclass 300 pathway fit?

The subclass 300 pathway may fit if you are not yet married and plan to marry your prospective spouse within the visa period. Under Home Affairs subclass 300 guidance, the applicant must be at least 18, have an eligible prospective-spouse sponsor and have met that person in person as adults. The applicant must be outside Australia when applying.

Applicant eligibility and sponsor eligibility are separate checks. Sponsors ordinarily must be Australian citizens, Australian permanent residents or eligible New Zealand citizens, and sponsorship requires approval under Home Affairs sponsor guidance. Having a fiancé living in Brisbane does not, by itself, establish sponsor eligibility; federal visa criteria apply nationally.

Subclass 300 versus married or de facto partner pathways

Compare the intended-marriage pathway described in the subclass 300 guidance with the existing-relationship pathways described in the 820/801 guidance and 309/100 guidance.

Application location and decision location are different questions. Home Affairs permits decisions on 300, 820 and 309 applications in or outside Australia.

For married and de facto pathways, sections 5F and 5CB of the Migration Act require a genuine, continuing relationship, an exclusive commitment to a shared life, and living together or not being permanently separated. A wedding alone does not replace these relationship requirements. Start your pathway comparison by identifying whether you are planning a marriage or already have a qualifying married or de facto relationship.

What evidence supports your meeting and marriage plans?

For a Prospective Marriage visa application, organise evidence around the adult in-person meeting and your genuine intention to marry within the visa period. Use the official subclass 300 checklist to identify the documents needed for your circumstances.

A practical preparation sequence is:

• Record the meeting: identify when and where you first met in person as adults, and distinguish that from when you first communicated online.
• Select supporting records: consider available travel records, dated photographs or other records that support your account. These are illustrative options, not a universal compulsory list.
• Explain the marriage plan: set out the intended timing and arrangements, showing how the plan fits within the visa period rather than leaving it as an unspecified future intention.
• Check consistency: compare dates, places and plans across both people's statements and supporting documents. Explain genuine gaps rather than inventing events or records.

Organising relationship statements and supporting documents is also useful preparation for later partner-visa work, but the immediate focus here is the meeting and intended-marriage evidence for subclass 300.

For non-English documents, Home Affairs requires English translations alongside the originals. Its subclass 300 document instructions require Australian translators to have NAATI accreditation; overseas translators must provide their contact details, qualifications and experience. Upload clear colour scans and combine the pages of a multi-page document into one file.

How long does the visa last, and when must you marry?

Checked 9 October 2026: Home Affairs subclass 300 guidance describes a stay period normally lasting 9–15 months from grant. Your grant letter controls the actual period, and the intended marriage must occur within that period.

Once a visa is granted, check the letter for:

• the actual stay period and expiry date;
• the visa conditions that apply to you;
• how the marriage timing and preparation for a later partner application fit within the available period.

Do not treat the general stay range as your individual permission or as an application processing estimate. For processing information, consult the official Home Affairs processing guide; no numerical processing range or personal decision forecast is given here. Recheck the linked instructions when preparing your application.

What happens after you marry?

1. Prepare evidence of the marriage and continuing relationship. A marriage certificate is important, but it does not establish every spouse relationship requirement. Section 5F of the Migration Act also requires an exclusive shared-life commitment, a genuine continuing relationship, and living together or no permanent separation.

2. Plan the later application before the 300 expires. If you wish to settle in Australia, Home Affairs subclass 300 guidance directs couples to apply for the combined 820/801 partner visas after marriage and before the 300 expires. A subclass 300 grant is not permanent residence.

3. Check the later application's requirements separately. The applicant and included family must be in Australia when applying for 820/801, according to the 820 guidance. Check application validity, eligibility and evidence requirements rather than assuming the earlier 300 grant establishes eligibility for the later visas.

For a Brisbane-connected couple, an Australian migration lawyer can assess the Prospective Marriage visa pathway, review sponsor circumstances, identify gaps in meeting and intended-marriage evidence, and explain the scope of later partner-visa work. In an initial enquiry, include your application location, relationship stage and intended marriage timing. Request a written scope clarifying whether the proposed work covers only subclass 300 or also the later 820/801 application.
