I’ve never heard completing an eligibility form first. Sounds dodgy but not surprising for Victoria.
I would go and try and get in. It’s a good education into how the court works.
I juried once in NZ for a domestic abuse case.
I also got called up for jury service about a month after moving to Australia in 2007. I didn’t get picked for that one and haven’t been called up since. There’s a good chance you won’t get picked even if you do go.
Just go for it. We’ll all end up in the corrupt system at some stage. Might as well be on this side of the offence.
