Edit July 2017 – It seems a lot of people are still coming to this page from search engines. If this is you, hi! If you are using Tableau 10.2 or later let me be clear… you no longer need these files nor do you need to use the techniques described to show custom regions. Tableau can now read the ESRI boundary files from the ABS website natively. This gives you a much better experience and makes your workbooks much simpler. Check out the Tableau blog post on this new feature here.
One of the most popular posts on my blog is Australian region boundaries in Tableau. Many people link through it to find the ASGS boundary data files I have converted for use in Tableau. The Australian Bureau of Statistics recently released an update to the ASGS main structure with changes to:
- Mesh blocks
- Statistical Area Levels 1 – 4 (SA1 – SA4)
- Greater Capital City Statistical Areas (GCCSA)
You can read the details about the update here.
I’ve updated the boundary files for these structures and put them in the Dropbox folder, here.
I’ve also generated the boundaries at different resolutions – 10m, 100m and 200m. The finer the resolution, the more data points (e.g. the SA1 file has 781K points @ 200m, 1M points @ 100m, and 2.6M points @ 10m). Use the version that best suits your needs – if you are showing the whole country, use the 200m resolution file; if you are zoomed in on a small area use the 10m resolution file.
