Hi mate
You are very likely to find out the info you need, the raiders are a top bunch of people who fish and have wide knowledge on the areas you fish.
I my self fish botany quiet often.
There are various spots that produce good ammounts of quality fish for example molinoux point holds
kingfish, but it can take a while before you find the fish, some days they are there some days they are not.
The kings are normally caught around the various markers/ drums where the ships tie up, but have somepeople have experienced they can show up any where any time taking anything.
Along brighton le-sands there is some top fishing for flathead, the flattys are there most of the time.
The bay also holds schools of tailor at times, not over sized fish but top fun on light gear.
The bay is unpredictable and so are the various rivers, creeks and sorounding areas.
Some of the offshore fishing is good when you get the tides, water temp, location right, a good spot for reef fishing/ bottom fishing is the merries reef complex just north east off cronulla beach has good fishing for snapper, flathead, kingfish, nanaguai, mowies, other places that are like this is the snapper hole off kurnell.
I have fished the cooks river for big flathead, bream once got a snapper that was 38cm from memory.
Have fished the georges river a few times chasing jews and member DOMZA who was fishing with me caught a 89cm flathead.
The bay is very unpredictable, but i guess fishing is just like that.
Good luck with it all.
cheers james
