If your partner is overseas and you’ve been planning a wedding but haven’t started the visa process — you might be about to make an expensive mistake. Many couples apply for the wrong visa, waste thousands of dollars, and lose precious time.
The good news? There’s a pathway specifically designed for you: the Prospective Marriage Visa (Subclass 300). And in Australian immigration circles, it’s one of the most underused — and misunderstood — partner visa options available.
What Is the Prospective Marriage Visa?
The Subclass 300 is a temporary Australian visa for engaged couples who want to marry in Australia. It sits within the broader family of Partner Visa Australia options and is specifically designed for situations where the overseas partner cannot yet meet the requirements of the Offshore Partner Visa (Subclass 309/100).
Under the standard Partner Visa requirements, de facto couples must demonstrate at least 12 months of cohabitation — or provide compelling evidence of a registered or formally recognised relationship. For many genuinely committed couples who have met across borders, this simply isn’t possible yet. The SC300 fills that gap.
Think of the Subclass 300 as the legal bridge between being engaged overseas and beginning your permanent life in Australia together.
How Does It Work?
The SC300 visa is an offshore Partner Visa — meaning the overseas applicant must apply from outside Australia and must also be offshore when the visa is granted. Once granted:
- You have up to 15 months to enter Australia (depending on visa validity)
- You must marry your sponsor within 9 months of the visa grant date
- After marrying, you apply onshore for the Partner Visa (Subclass 820/801)
- Two years after the 820 is lodged, the permanent stage (Subclass 801) is assessed
This three-stage process — 300 → 820 → 801 — leads to permanent residency. By contrast, the offshore Partner Visa 309/100 is a two-stage process for those already married or in a de facto relationship.

Partner Visa Requirements: What You Need to Prove
Australian immigration authorities assess applications carefully for genuineness. For the SC300, you don’t need to prove years of shared life — but you do need to demonstrate that your relationship and your intention to marry are real. Key Partner Visa requirements for the SC300 include:
- A Notice of Intent to Marry (NOIM) — mandatory for this visa
- Evidence you have met in person at least once (online-only relationships do not qualify)
- Photos together, travel records, chat logs, and communication history
- Statements from family and friends who know the relationship
- Engagement evidence: ring receipts, party photos, wedding planning materials
- Health checks (medical examination via an approved panel physician)
- Character checks (police clearances from every country lived in for 12+ months)
The sponsor — your Australian partner — must also meet eligibility criteria. They must be a citizen, permanent resident, or eligible New Zealand citizen, and they cannot have sponsored another person for a Subclass 300 in the previous five years.
The Cost Reality: SC300 vs Offshore Partner Visa
Here’s where honesty matters. The SC300 pathway is generally more expensive than going straight for the offshore Partner Visa 309/100.
The base government fee for the SC300 is AUD $9,365. After marriage, you’ll pay a reduced fee of AUD $1,560 to lodge the onshore Partner Visa (820/801) — bringing the total to approximately AUD $10,925 in government fees alone.
By contrast, the 309/100 offshore Partner Visa costs AUD $9,365 and covers both the temporary and permanent stages in one payment. If you can meet the Partner Visa requirements for the 309, it’s the more cost-efficient route.
However, cost efficiency means nothing if you apply for the wrong visa and get refused — losing every dollar paid with zero refund.
Processing Time: What to Expect in 2025–26
Australian immigration processing times fluctuate based on application volumes and caseloads. For the SC300, realistic timelines in 2025–26 range from approximately 12 to 26 months. Well-prepared, complete applications tend to move faster.
During processing, the applicant must remain outside Australia (they can apply for a Visitor Visa Subclass 600 to visit during this period, but must be offshore when the SC300 is granted).
Who Should Consider the SC300?
The Subclass 300 is the right choice if:
- You are engaged but cannot demonstrate 12 months of de facto cohabitation
- You are in a long-distance relationship and have met in person at least once
- You have a genuine commitment but lack the evidence base for the 309
- You have a clear wedding plan and can commit to marrying within 9 months of arrival
It is not suitable if you are already married, already in Australia, or if you’ve never met your partner in person.
Why Work With a Registered Migration Agent?
Australian immigration is complex. Partner visa applications — including the SC300 visa— are assessed holistically, and cases are refused every year due to insufficient evidence, sponsorship issues, or incorrect visa selection.
A registered Migration Agent (MARN-registered under the Migration Agents Registration Authority) can assess your eligibility, guide your evidence preparation, and help you avoid the costly mistakes that delay reunification for years. When you’re trying to migrate to Australia to be with the person you love, professional guidance isn’t a luxury — it’s a safeguard.
