Experience sharing: how to keep Australia's PR (green card) status?

Mainly to meet the requirements of immigration supervision (residence), the Australian permanent residence visa is valid for 5 years, and the next 5-year visa needs to be replaced when it expires. The replacement conditions mainly depend on whether you have lived in Australia for 2 years in the past 5 years. Of course, if you can't meet this residence requirement for a long time, you can also apply for Australian citizenship after living in Australia for three years within four years, and there will be no residence restrictions after joining the nationality.
