Handy tips - I just gave a paper at MWSUG 2016 and SGF 2017 on this very topic, http://support.sas.com/resources/papers/proceedings17/1307-2017.pdf! There's quite a bit of data to be had at the Australian postal code level and many cities, towns and larger entities are creating data farms with municipal data. With PROC MAPIMPORT, the sky, and beyond, is pretty much the limit. In the paper, I demonstrate using PIGWAD data and shape files to map Mars. I have to put in a plug for SAS MapsOnline http://support.sas.com/rnd/datavisualization/mapsonline/html/home.html. There is so much useful information and data, including British geocoding. In addition, Robert Allison of SAS has an amazing site with samples galore (including code and free ebooks to help you get started.) http://www.robslink.com/SAS/Home.htm. Happy Mapping, all.
