I'm another one for the old bread crumbs for burley and little prawn pieces under a pencil float. We catch snub nose gar in North Pine Dam...well my little boy catches them while I chase bass. Big blue back ones in there, thousands of them.
I stand waist deep in the water out there and the gar come right up to you when you bring your bass lures back in. They'll even have a go at big lures but the trebles are too big to hook them.
I've seen quite a few blokes fishing for them to use as jack bait in the river afterwards.
