I am Australian. When I was assigned Jury duty in 2016, my Company continued to pay me (I think this is a legal requirement if you are a full time employee), I showed my manager the letter from the court and I was instructed to enter a leave request via usual HR system we use - there was an option for Jury duty.

I was also paid by the court for attending jury duty (a physical check that arrived in the mail a few months later). It was not very much money (I think around $20 per day) - this money was supposed to cover things like Transport, parking fees and meals. In my case the trial was called off after 3 days so the check was for around $60.

Maybe if you are part time or on a contract it is different.
