Will a subclass 870 visa give my parents permanent residence in Australia?

The Sponsored Parent (Temporary) visa lets parents stay for long, continuous periods, but it never converts to permanent residence by itself, and after the 10-year cumulative limit no further 870 can be granted.

Families who want a permanent outcome should look at the separate permanent parent visa categories, which have their own eligibility tests, balance-of-family requirements, and processing arrangements. The 870 can be a useful bridge, but it is not a permanent-residence pathway.
