ASI groyne and rockingham yacht club jetty

We went out chasing snapper in the middle of a storm.casted out big baits on a double hook rig mulie/squid.At the jetty we landed a big ray but then sat with baits out for bout 2 hours with nothing.Tthe bloke next to us was catching sum nice whiting on a small rig i didn't wanna downgrade though just for that chance of a snapper.Moved on to the ASI groyne kwinana but just got plauged with port jackson sharks for a bout 2 hours.Then it dropped off with not a bite for another hour and a half.Then we called it quits.Was perfect conditions to land 1 but i reckon if u manage to get a nice snapper off a beach or jetty in the sound your just 1 lucky son of a gun
