Boyfriend wants to fake marriage and get an Australian PR? How long will it take to get it according to the current policy?

PR should come down within 1 year, but if you divorce immediately, the Immigration Bureau will check. Once you find out, you will be deported immediately. I don't quite understand why you love your boyfriend. He must engage in public relations. The current policy is that if you can't stay in Australia for three years within five years after you get the PR, the PR will be invalid. After three years, it is impossible to become an Australian citizen and live in China as in the past. I really don't understand. Five good years were spent on public relations.
