As part of the Logan Food Gardeners' online community group, you can go to Crop Swapping Groups which happen every couple of months. This is where members get together and either purchase or swap home grown produce. It's brilliant as you can collect fresh home grown produce and also off-load surplus produce that you've grown. There are similar groups in all capital cities and membership to most of them is free.
A good tip is to price fresh produce realistically and also be prepared to swap items, and check what items each Crop Swap sells before you go.
