If you don't know of it already, you might be interested to have a look at a site called
Mapping our Anzacs. It was developed by the National Archives a couple of years ago and links directly to copies of the service records which are held by the National Archives.
The main site is
Mapping Our ANZACs.
The 'scrapbook', where people have been posting photos, comments, memories, photos of graves and so on, can be found here:
