Here are a couple of sites for you. One is not a supplier as such, but is about bushtucker. The business is run by Aborigines and they may have contacts. The second has lots of useful links. And the third is the results of a Google search for 'bulk Australian herbs'. You won't get your herbs by the pound - we are metric here, so it will be by the kilo(gram) or part thereof. 500g=1lb.

If you contact The Dilly Bag people, ask them to refer you to their friends who have a massage/essential oil outlet in Florence Street, Wynnum, Queensland (can't recall the name of the shop). They use all Australian native products, and must have a supplier. They have things like Riberry Face Cream and so on.
