One of the major new features in iOS 6 is the inclusion of Apple's own mapping technology. Building a map isn't easy, and the first screenshots from the beta version suggest that even for well-covered locations such as the Melbourne CBD, Apple has a lot of work to do.
As Luke over at Gizmodo notes, screenshots posted on Reddit over the weekend highlight the contrast between the level of detail available in iOS 6 compared to Google Maps (which will essentially be getting ditched as Apple's preferred maps provider). Apart from the lower level of detail, what jumped out at me was the bits that are entirely wrong. For instance, the first part of Swanston Street is missing entirely, as you can see in the screenshot above. That's going to make it very difficult to catch trams or visit the Town Hall.
Yes, I know: this is only a beta, so it's entirely possible Apple will improve on these maps before the general release. It certainly needs to if these are typical of what's already in the system.
