I'm not trying to contradict you about phishing, but the US, UK and Canada has it a whole lot worse than Australia, yet they don't have the same restrictions as Australia.

It so bad that I've seen multiple scam warnings: in NZ if you get a SMS message from a business/government, and it's from Australia, treat it as red flag.
