Subclass 309 vs 100: What's the Difference? (Australian Partner Visa Explained)

If you're in a relationship with an Australian citizen or permanent resident and want to live in Australia together, you'll need a partner visa. But when you start researching, you'll quickly encounter two numbers: 309 and 100. Here's what they mean — and why the distinction matters more than most people realise.

The Short Answer

The 309 and 100 are two stages of the same partner visa application. You apply for both at the same time. The 309 (temporary) is granted first, and the 100 (permanent) follows after a 2-year assessment period — provided your relationship is still genuine and ongoing.

Think of it as a two-part process: Australia lets you in on the 309, watches to see that your relationship is real, and then grants you permanent residence on the 100.

Why the 2-Year Wait Exists

Australia takes partner visa fraud seriously. The 2-year assessment period exists because the Department of Home Affairs wants to see that your relationship is genuine over time — not just at the point of application.

This means the work doesn't stop when your 309 is granted. You need to continue building evidence of your relationship throughout the 2-year period, ready for the permanent stage assessment.

What Most People Get Wrong

The most common mistake we see is treating the partner visa as a one-time application — lodge it, wait, get the visa. In reality, it's an ongoing process that requires consistent documentation and attention over several years.

Couples who understand this from the start are far better positioned than those who find out halfway through.
