Yes, agreed. At a quick look, the quality seems to be better in some areas than others, some of the suburban areas of Perth come out pretty well. Anyway, if it's useful to anyone, I now have a folder of ~1700 .osm files for all the suburbs in Perth, happy to share them if anyone wants. I'll probably do some tinkering with them, as a JOSM learning exercise.
