Yeah I've heard that term used but not as often as frogs and lizards.
In Vic we have a bag limit of 2 X 60cm+ flatties per person per day but I think it's something like 20 for flatties less than 60cm. We used to catch our 4 bigguns, a few smaller ones for the freezer then up pick and move onto the bream. But they were so easy to catch at Mallacoota it wasn't even an effort, just drop the plastic in the right spot and wind them in. It's just not like that these days.
