No they don't. They come from the various states' geographical names boards. Unfortunately, none of them appear to have released their geodata, except via PSMA ($$$). The current ABS suburb data are based on "mesh blocks" from the ASGS, which are their smallest dividing buckets for census data. (The pre-2011 ASGC suburb boundaries were made using a similar process.) This means that their boundaries can deviate from the official state boundaries, especially in sparsely populated or non-residential areas where whole localities can even be missing altogether from the ABS data.

But they usually realign the boundaries when things like this happen. _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
