If there's no obvious connection to the place, the other explanation is that she's using a VPN, and her IP address decodes to one that's based in Oz based on whatever AW use for a location-based-on-IP-address lookup.

Same kind of thing that'll happen if you use a service like NordVPN in order to watch American Football on CNN (for example).
