Mate, probably a bit to late to reply, the hawksbury does get hit by trawlers and fishing can be on and off, i have found camping down there to be the best thing, i fish the broken bay area alot, i have found that a small selection of different baits can be good, a lot of patience is required though, i have found that the run in tide at the F3 bridge is great for jewies in the arvo and a run in at flint and steel is good for the flattys, broken bay is really great but you have to0 be where others arnt.
