A recent post on the Exploring Military History blog on "World War 1: selection of non-fiction books" which included a list of junior non-fiction, and a previous post on "World War 1 through children's fiction", I thought worth passing on.
There is a booklist contained on the Empire Called and I Answered website, called "Sources", which covers all the material I have looked at for any mention of the local volunteers. This list doesn't have as much current material as Vicki's list, but may suggest some less well-known material published a bit closer to the war which may be useful for research.
And just for fun, I keep a Pinterest group of covers of WW1 Australian history books.
