Hi Lyn, I live on the West Coast and I brought my first Yacons from Dayleys fruit tree nursery NSW. They are great people to deal with and have a great web site. Regards Robert Devine. 0400614698.

Type in Yacon for sale in Australia in google - Ebay - Gumtree - other companies - green harvest has very good info about them. Look around to get a good price. Some places want 10-15$ and the same again for postage. Could try Bunnings.
