Hi Bardo, are you still looking for Native edible books?, yeah I have a few Tim Low ones as well plus a few others.
I also have a copied to PDF version of Tim Low's out of print Wild Herbs of Australia and New Zealand and can send you that if you're interested. I copied it from a library years agoand then copied it to my computer to PDF. I had to make it in 2 sections because it was 2 big to email as one.
Another one by AB & JW Cribb called WIld Food in Australia os ok as well but dosent have much in the way of ikkustrations though. It is still good for general info, here's a link to one for sale:
