To use Shonkymaps install Garmin:
Training Center; then
MapSource; then
nRoute
The first two are available from Garmin website. Google is your friend to find the last one.
I have one of these USB GPS. It works well. A$35 inc postage .
It connects via USB only. I don't think you really need a Bluetooth one because you have to power the GPS so it might as well be plugged into the PC.
It has an external antenna so it may be better in downtowns, not that we have many of those in Oz. Ho Ho.

You would have to buy GPSGate to convert 4800 NMEA to Garmin format.
I have a series of legally free 50k and 100k raster maps of NSW and Vic which I found somewhere on the Internet. Search Oz 4*4 and GPS web sites for links.
You have to use Oziexplorer to view them.
Official OziExplorer Web Site
If you can't find them ask and I will look for the links in my archives.
Don't dawdle. I leave for Europe (Paris to Turkey via Italy and Greece, return via Bulgaria and Romania and then follow Danube from mouth to source in Germany) for 4 months on Wed.
You can also buy (or acquire) raster 250k Natmaps 2008 A$99 that you also need Oziexplorer for.
