Dave, while it is harder this time of the year you might have to look at what your using for the lures & the size of line you are using?
What species are you targeting?
If your fishing for the bread & butter species like bream, flathead, whiting, snapper etc then your fishing a bit heavy imo, also it could be worth changing over to fluro for your leader material .
If your fishing around rocks then sure up your leader BUT heavier leader usually results in less hook ups.
What about bait a back up? I mostly use SP's & lures but hey if your not catching fish then I throw in a bait.
Also use the forum search tab, some good info might just be at your finger tips, even though some of these are older it just gives you an idea what/where/when & how-
