There is nothing special about the memory card (referred to as mc below) - anything that fits will work.
Andrewp has made maps (eg OMS-VIC-AU is Victoria topo) for each Aus state and also for NZ North Island and South Island (see tastrax link above). They are free (thanks andrewp) and better than any of the alternatives (imo).
Download the map files to a computer. Connect the mc to the computer and, on the mc, create a folder named garmin and save the map file(s) into that folder (see note below). Then put the mc in the gps and turn it on - the GPS will see and load the map(s) automatically. FYI; any img mapfile in a garmin folder on the mc or the internal memory will load automatically.
While you're connected to the mc, create a folder named gpx as well. You can put gpx files (tracks, waypoints, routes) in this folder (of course, those files can also go into the gpx folder on the internal memory)
On the GPS, you may need to enable the map to see it.
NOTE: I suggest you only copy, to the GPS, the map(s) you're going to use (to either mc or internal). If you copy them all to the GPS, each time you turn on the GPS, it will take a long time for all the maps to load. You can delete and re-copy anytime.
Let us know how you go and yell if you still have problems.
