i've recently started fishing land based at brisbane waters, and was taken to a 'special' spot by a mate and there was another group of guys already there...
they were pissed and laughing and having a good time, but left around sunset...
we moved over to take their 'better' spot, and i remarked to my mate "geez, those guys musta been here half the day, but there isn't a trace of them being here!"
my mate replied that it was like that up here, "you gotta keep it clean"...
i mostly fish middle harbor, and often clean up some scraps, but nothing like in your pictures....
no wonder you are SORBLE, it would make me ANGRY!
how hard is it??? you buy bait - it comes WITH A BAG - use it for your RUBBISH!!!
