Hey and well done on your first king. I thought i would share a few of my spots as the sea is there to share. Firstly for squid near the spit. I always go just before first light and can usually raise a couple at least. My most reliable spot is to the left of the restaurant if you are facing land. There is sandy area where people hire yaks from. Bright lights shine off this wharf and all around there seem to hold squid. They are small but good bait size used whole. People drift between the pillons but i find this less productive.
Yakkers i have had trouble getting at Balmoral as the sweep are everywhere. I launch from Drummoyne and go past Clark Island. There is a little wharf on Clark Is, on the side nearest the bridge and this has bucket loads of them. I use a tiny hand line with a tiny sinker with one size 12, i think, hook. Jigs are good but i find one hook is so much easier to deal with. You get one or at least drop on on every drop. Mix some bread in a bucket with water and throw some of that in and they will swarm.
Hope your bait collecting improves. Cheers mike.
