After some discussion in other forums about the most cache dense areas in Australia (see here) I've decided to update my Geocache density maps from a few years back. Hopefully this may provide a reference for people to be able to plan caching trips to areas with high density of caches.
Download Link
The current maps have 20km x 20km grid cells and a key to the colour scheme is provided in Google Earth when you download and open the file. The maps are approximately 100kb so won't break the download limits. The data is also current as of 7th October 2010 and includes both GCA and GC caches of all types (except trig points).
If you are interested in regional density maps (i.e. a map of Melbourne with 5km x 5km grid cells) then request it on this forum and I will see what I can do. As they are produced I'll post them onto the forum for all to use.
