As said above, if you're looking for Kings its best to sound them out rather than jigging in the dark. You should see them where the bait stacks up.
In terms of bottom bashing, there are definitely plenty of species on offer and its quite a lucky dip. A few weeks ago we pulled kings, morwong, perch, nannygai, leatherjacket, snapper and pigfish. Standard paternoster with a suitable sinker will do the job.
Good luck!
