Hi Mate.
Mitch, James and I have been getting into them a bit lately with a variety of lures. Zoom Tiny Flukes go off (bassminnows work aswell), the Maria Little Bit metals work, and Snapbacks would be my choices of lure. They aren't super picky but we've had more success on those lures than others.
I've personally never bothered with Berley but I'm sure in places it will be highly beneficial.
Just jig them on a 1/8th jighead (bullet, round or minnow) quite agressively with pauses. Quite often I get hookups while I'm ripping the lure back to the surface...they love some fast agressive movements at times with pauses. A lot of places we get them have juvie sambo's too which make for great fun.
