Victorian police (back home in Australia) have issued a warning to users of iOS maps. Several tourists who attempted to navigate to the country town of Mildura (a popular tourist location), actually get sent to the middle of a state park.

That said, the road to Mildura is pretty well sign posted, and you should be extremely suspicious of any suggestion to turn of a major highway onto a bush track that only looks suitable for 4x4s. This is also why it's good to have (and be able to read) a real map. :)

Just ridiculous really!! Read this in the Age today, & shook my head... I don't want to upgrade to a downgrade!! Mildura is a major country town!! That Apple has a big bug in it!!!

I'm told that there should be a Google Maps for iPhone that should be out before the end of the year. :)

Already out are a number of solutions that work well.  This includes Nokia's Here maps, Waze, and others.  Nokia earns the distinction of being the only map to have my Uncle's proper street name.  Google, Apple, TomTom and Waze all have 7 year old data for that area.

Nokia's always been up towards the top of the pile when it comes to mapping, for a very long time, oddly enough.

Uhoh: http://au.news.yahoo.com/technology/news/article/-/15610781/police-warn-of-safety-concerns-from-google-maps/

I think the lesson here is, stop using GPS when down under :)

I've been down those roads a few times, and they're certainly a valid route, though as the article says parts of Wild Dog Road are unsealed and not suitable for large vehicles or driving at high speed (take a look on Street View). At least it's "correct" in that you don't end up stranded in the middle of nowhere. :)

The local paper maps like Melways will also show you unsealed roads and generally also have extra information like "unsuitable for trucks". Again, a lot of it is the quality of the database information.

I don't consider that to be a screw-up by Google Maps. They do not cater to providing appropriate routes to buses and heavy vehicles, which have ALWAYS had their own requirements and routes not valid.
