Is there a time zone for Australia inside the Regional setting for the site collection

Question

I am working for a client in Australia, and i am trying to set the time zone to be equal to Australia, but i could not find any:-

any advice?

Answer 1

Australia does not have a time zone. It has five.

Even on your screenshot one can clearly see 3 Australian time zones:

Likely, you will need UTC+10 Canberra, Melbourne, Sydney since most of Australia lives there.
