the entrance is great for flatties on soft plastics, at the moment if you drift up the nth channel you will catch one after another, not huge in size but all good fun,
and as for kingies, if you drive about ten mins nth theres a boat ramp at cabbage tree bay, can catch good numbers of squid casting stright onto reef from ramp, or once boat is launched head nth to hargraves reef, throw some bread out and will have a tank of yakkas in no time.
once you have bait, head back down sth towards lighthouse and you will see a bommie maby 500 m of shore, down rig or just send the livies out around there(called "the bull") and hang on,
is alot of rats mixed in but the bigger fellas have been lurking around too.
also have heard alot about terrigal for kings but to try it out personally.
good luck mate
