The Partner visa subclass in Australia is subclass 820/801 for onshore applications. These visas allow the spouse or de facto partner of an Australian citizen, permanent resident, or eligible New Zealand citizen to live and work in Australia.
The subclass 820/801 visa is a two-stage process. The first stage is the temporary visa (subclass 820), which allows the partner to live and work in Australia for up to two years. After the two-year period, if the applicant continues to meet the requirements, they can apply for the permanent visa (subclass 801).
The subclass 309/100 visa is also a two-stage process. The first stage is the temporary visa (subclass 309), which is granted to the partner who is outside Australia when they apply. After the two-year period, if the applicant continues to meet the requirements, they can apply for the permanent visa (subclass 100).
The Prospective Marriage visa (subclass 300) is an Australian visa that allows individuals who are engaged to an Australian citizen, permanent resident, or eligible New Zealand citizen to come to Australia to marry their partner.
Overall, the Prospective Marriage visa can be a good option for couples who are engaged and looking to marry in Australia. The eligibility requirements and application process for these visas may vary, so it is important to carefully review the requirements and seek professional advice.
