Wild sourced plants aren't eligible for registration to restrict ownership to a particular individual or company either under Plant Breeder's Rights or even Australian Cultivar Registration Authority.
My email reply from a certain Botanical Garden is that it is listed as vulnerable and the location, trade and every other possible commercial activity is restricted under Nature Conservation Act 1992, Vegetation Management Act 1999 and Environment Protection Act 1999. So in effect the QLD government is trying to protect the very limited wild populations and they are figuratively speaking under lock and key/maximum security prison [American analogy]

which is contrary to people who feel like they need to try this as a herbal concoction right this bloody minute, is actually very, very good news.
Yep I used my work email to enquire about the Blushwood berry (I assumed it would get me faster response that way) but I think that it made them feel justified about slapping me with 11 paragraphs of legalese right back
