Partner visa (subclasses 820 and 801)
About this Visa
The Partner visas (subclasses 820 and 801) allow the partner or spouse of an Australian citizen, Australian permanent resident or eligible New Zealand citizen to live in Australia.
The temporary Partner visa (subclass 820) is granted first and lets you stay in Australia while the permanent Partner visa (subclass 801) is processed.
What you can do
The temporary Partner visa (subclass 820) lets you stay in Australia until a decision is made on your permanent Partner visa (subclass 801).
Long term relationship
If, at the time you apply, you have been in a long term relationship with your partner, your permanent Partner visa (subclass 801) visa will be granted immediately after the temporary Partner visa (subclass 820) visa.
If your current visa is about to end
You can stay in Australia on a Bridging visa if you have already lodged your application.

How long the sponsorship lasts
