There are three books (that I know of) that are available in Australia specifically about EC and two DVDs.

The books are:
"Infant Potty Training" by Laurie Boucke - very comprehensive with details on how to start at any age and also gives information on a variety of cultures
"Infant Potty Basics" also by Laurie Boucke - a cut down version of the above book, omitting so much of the traditional culture stuff, but also telling how to start
"DiaperFree!" by Ingrid Bauer - how to start and more of "why" to start - talks about respect and other emotional things.

The DVDs are:
"Nappy Free" by Nicole Moore - a practical and pragmatic documentary on elimination communication based on an Australian community doing it
"Potty Whispering" by Laurie Boucke - a two DVD set with interviews from parents, care-givers and medical personnel and footage of a variety of babies and toddlers
