Software - OziExplorer:

Detailed digital maps - MapTrax:

Ozi uses raster format maps, ie pictures (like digital photos), jpg, tiff, ecw, or their own format ozf2. Any line, word or shape is made up of pixels.
Each picture must have georeference data in a special text file, these are saved as .map files.
Eg In one folder of charts I have a 'Melbourne Approaches.jpg' & a 'Melbourne Approaches.map' which must be used together.
So you can scan a paper map, save the jpg file & calibrate it using the software that comes as part as Ozi to create the .map file.
Advantages, Once you have bought Ozi ($140) you can create maps very cheaply if you can beg or borrow the paper versions.
Disadvantage, while you can zoom in & out slightly, the picture is always intended to be looked at, & display it's data at the scale it was printed in.
This is how I got the charts of Port Phillip that I use in Ozi.
There are also many commercial, high quality, land based maps available for Ozi.

.....there are also free maps of Vic for OziExplorer (thanks to festy) - no idea of the quality (for your intended purpose) compare to the commercial product but worth a look ...
