May be they'll email the voter information card now because of COVID? Not sure. I'll register on 23rd August after oath. I'll keep you guys posted on what happens after that.I mean I didn’t expect there to be a federal election until 2023 so I wasn’t really rushing lol. And I was aware I could register at the poll on election day, having processed new voters myself as a volunteer.
(But yeah, you’d need proof like a citizenship certificate/card or passport.)
Just so much easier if you get the voter’s information card in the mail.
