Clever PR ruse?
Why would Australian police make such an announcement? Have they, truly, linked an increasing number of people lost in the Outback with the use of iOS 6 Maps? Are Australians who travel through hot and distant desert regions really that dimwitted? And why wouldn't the police simply contact Apple to correct the error? There's something fishy here.
I have also searched for Mildura on both Google Maps and iOS 6 Maps, and received identical results. If you take this article at face value, there's likely something off about your critical thinking skills.
