I'm assuming you've had a fair dump of rain down there Noel. When this happens as the schools are gathering for their spawning run they are triggered to run to sea early, like dam barra heading to the dam walls in rain events. The fish will not be rowed up yet. They're known as washouts. No row but for eating or bait the're fine and plentiful. They run to sea, head north and duck in to the next estuary.
