After my subclass 189 is granted, how long do I have to enter Australia, and does it lead to citizenship?

Once your subclass 189 visa is granted, you and your included family members typically have an initial travel facility of around five years in which to make your first entry and validate the visa. You do not have to relocate immediately, but you must enter within that window.

Because the 189 is a permanent visa, it places you on the pathway to Australian citizenship. After living in Australia as a permanent resident for the qualifying period and meeting character, residence and other requirements, you can apply to become a citizen.
