The Sydney Farmers Market is held every Friday between 10AM and 2:30PM at Cook Phillip Square in front of Saint Mary's Cathedral. www.hawkesburyharvest.com.au
Having had missed the inaugural episode, I did make it to there eventually. Also, managed to fill up my bag with some nice spreads (jam, chutney, honey), baked goods and produce. Good yield.
BTW, it's true what they say about Farmers Markets -- link
