[tor-relays] Is a relay on mobile broadband possible in Australia?

Teor,
>>> Most mobile carriers use carrier-grade NAT.

Thanks for that.
But yet again, I do not have anything but a 'phone passing data via wi-fi to a computer (a Raspberry Pi in this case) so there's no router.
From what you say and what I've tried Optus is having a joke and limiting what we can do with 'broadband internet'.  Their parents weren't married.

I have numerous foreign VPS running mostly without drama.
