Gday Maharg, and welcome to bonsaiTALK!
Keep an eye out for a book called "
Bonsai with Australian Native Plants" by Vita and Dorothy Koreshoff. Also, articles here at bonsaiTALK by a Member called
peterh might be of interest. Check the links in my signature for some great images of Oz Native Bonsai.
Good luck.
