In one of my recent posts I tried to explain basic concepts behind map projections, coordinate systems and geodetic datum and outline characteristics of the ones used in Australia.

The booklet has been published by Geoscience Australia and is an excellent introduction for anyone interested in maps, orienteering or GPS navigation. National Mapping Agency within Geoscience Australia produces topographic maps that cover entire country at different scales. They are available for online use from aus-emaps.com:
