Partner Visa: Partner Provisional Visa( Subclass 309 ) and Partner Migrant Visa ( Subclass 100) allows the partner or spouse of an Australian citizen, Australian permanent resident or eligible New Zealand citizen and you are outside of Australia.
The temporary Partner (Provisional) visa (subclass 309) is granted first and lets you stay in Australia whilst the Permanent Partner (Migrant) visa subclass 100 is processed. Moreover, you can also include your dependent children or stepchildren in the application
Obtaining the permanent Partner (Migrant) visa (subclass 100) is a two stage process. To be eligible for a permanent partner visa you first need to be granted a temporary Partner (Provisional) visa (subclass 309). You apply for both the permanent and temporary visas at the same time and pay only one fee. If you are granted the temporary Partner (Provisional) visa (subclass 309), you are eligible to be assessed for the permanent Partner (Migrant) visa (subclass 100) about two years after you lodged your application. You will need to provide further documents for this assessment.
If you have been in a long term relationship before you lodge your application, the permanent Partner (Migrant) visa (subclass 100) may be granted immediately after the temporary Partner (Provisional) visa (subclass 309).
