I've been manually loading up the suburb and LGA boundaries in Victoria from ABS 2011. Figured that would be quicker than waiting for everyone to reach a consensus on how to automate it and means it gets done "properly" In doing a manual load I am ensuring the boundaries share common boundaries with one another and the multipolygons close off properly. Those are pretty much impossible to do with an automated load. Even a few manual errors creep in but they are easily fixed.
As I understand it from the ABS website http://www.abs.gov.au/ausstats/[email protected]/0/a9421cdfb258e4a4ca2570ad00818509?o pendocument they are supposed to be the gazetted boundaries There are a few errors in the boundaries but I think it's easier to fix those once the main load is done. After that I'd suggest it's a manual effort to make any further changes. It's not something I'd want to do again from scratch. The question is what to use as a definitive source for corrections that is ODBL compliant. I've found some maps on http://www.vec.vic.gov.au/publications/publications-maps.html#5 but not sure if we can use them to make corrections in OSM to the ABS boundaries. Anyway - cross that bridge when we get to it.
