The 300 visa process to permanent residency
The prospective marriage visa pathway is, therefore, a 3-stage process to permanent residence, comprising the following steps:
Step 1: You first need to lodge a prospective marriage subclass 300 visa application, which, if granted, will allow you to travel to and reside in Australia for a period of up to 9 months to marry your Australian partner.
Step 2: Once you have married your partner (within the 9-month visa period), you are then expected to lodge a combined application for an onshore partner subclass 820/801 visa.
Step 3: Two years following lodgement of your combined subclass 820/801 visa application, the Department will assess whether you continue to satisfy the requirements for a grant of the subclass 801 visa, with a successful application resulting in a grant of permanent residence in Australia.
