There are plenty of areas all over the NE, but you will have research for the kind of gold you are after and suits your ability and equipment. I work mainly around Beechworth and Yackandandah but they are not really remote, although its not hard to find isolated spots. I would have a go on the Buckland as a first start. good river for sluicing and gold can be quite coarse if you find the right spot. If you have an SDC 2300 you could detect that size stuff under water.
