How long does it take to immigrate to Australia?

If your boyfriend is an Australian citizen or permanent resident, and you have lived together for more than one year, you can apply for immigration directly, but you must register for marriage within 9 months after arriving in Australia.

You can change your permanent residence if you get married. It was a temporary sign before.

You must be more specific about your situation. If you are in Australia, finding someone to marry is completely different. Because even if you get to know someone quickly and go through the formalities, you usually have to wait about a year, because the immigration officer depends on whether your relationship is true and lasting, because there are too many cases of fake marriage and real immigration in recent years.
