You ask questions in the wrong topics. Here are the maps - content but you have a problem setting up the software.

You do not know how to use the Forum, nor do you have any knowledge of navigation.

First, find out which navigation is best for Australia (iGO or MapFactor or Ozi Explorer or ExplorOz or...)
Then, dedicate some time to general information, read a lot.

If you do not have the will and desire to learn, then buy. For example [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ]...
and still you will need the knowledge to set it up
