Hi Daniel,
There is a very good book, Aboriginal Dreaming, by James Cowan that has a very good introduction to this. Also, many years ago there was a very large 'coffee table' book called The Dreamtime, or something like that that had pictures which truly evoked the power of that way of knowing. I have been searching for a copy of that book for decades, to no avail, but it was a powerful visual tool of understanding. Good luck to you!
