It’s kind of like Wikipedia, you have to cite the original source (State or council maps) rather than a 3rd party source.
The map data for my suburb is all kinds of wrong on Google Maps, there’s a park around the corner from me which is marked as a house for starters, blindly copying that into OSM would be a disservice.

Not necessarily original source - you can use aerial imagery from Bing, for example.
The actual requirement is actually a legal one. The data must be public domain or otherwise compatible with their license.
