Kerryn, I'm not sure where in Melbourne you are, but I go to the Abbotsford Childrens Farm farmers market (2nd Saturday of the month) or the Abbotsford Convent slow food market (4th Saturday of the month) for my blueberries. There is only one blueberry seller there so you can't go to the wrong stand by mistake - their name is Moondara (I think, but I'm not near my freezer at the moment to check). They are also selling fresh blueberries at the moment as it is their picking season so you have the choice of fresh or frozen. Other than that, I know there are other organic blueberries available at the organic stalls at Victoria market, but I have found the Moodara to be consistently the best.
