Theyre a pretty skittish species so i'd personally go as light as possible.
Any 7ft spinning rod with a small grinder (with a good drag) should be fine.
Use a light mainline - say up to about 12lb with 15lb fluoro leader with a smallish hook - 1/0 to 4/0 would work well. They have tiny mouths and love sucking your bait in and then spitting it out again. I've had some luck with small circle hooks on pulley rigs with prawn baits and sealice.
Most common rig though is a running sinker - barrel or ball - not too heavy. Up to 1oz or so should be perfect.
Alternatively you can fish weightless with just a hook on your mainline. Potent if drifting over banks. Especially if you can see them tailing.
Good luck
