the wollemi pine is australian from memory and was discovered (rediscovered by a group)
the find was kept secret for years until the propogated and started to grow them for distribution within australia.....I havent read the links but would assume they arent available yet to overseas....only within australia?

i have just looked for stockists in our area and there isnt any but WhisperzQ would be able to buy it readily if he had the $55 hahahah
