Hey mate,
i know what you mean. Been there, done that..
I fish pittwater a bit and might be able to offer you a few tips on spots to try and tactics.
1. For the moment stick inside the heads until you manage a few fish and then work your way outside.
2. Seeing the kings are around now i think you should fish one yakka on the bottom and one either unweghted or under a float. This will help you cover more ground as kingies, salmon etc are midwater and surface while the big flatties, bream and jewie are on the bottom.
3. My usual routine in pittwater is to gather live baits (maybe a dozen or so) and then head straight to the first spot and anchor up. I fish the two yakkas out the sides and another two rods. One with a prawn or nipper and another with a pilli fillet. Fishing this way will allow you to catch any kingies and salmon that are around on the yakkas and bream, flathead and whiting on the prawns and pilli.
4. Burley is a must. your mix sounds fine. In winter the small snapper can be a problem but at this time of year i would definitely use it religiously.
5. Here are a few spots to try for the moment.
* West Head- approximately 60-80m out from shore throw out a few livies and try and pick up a few salmon and kings.
* Coasters retreat- Another good livebaiting spot for kingies and salmon with the odd jewie around too. Can be patchy so if no bites after an hour or so then move on.
* Towlers Bay- Troll live yakkas and squid around the moorings for the kings.
* Clareville- same^
* Stokes point- My Neverfail Spot! Last time i fished stokes point was during winter when things really slow down. Managed a 54cm flattie, just legal and undersized snapper and a 30 cm bream. Lost a BIG salmon too next to the boat when he broke me off.. Best time is the first 3 hours of the run out however, it fishes quite well even at the bottom of the tide. Persist and you will get fish her!
Another tip i can give you is fish your livies either both on circle hooks with a locked up drag or 1 circle locked up and on octopus with a baitrunner system or freespool.
Good luck!
