Hi Billy, depends on what part of Botany bay shore you fish, its a big shore line! If your fishing in dead water put your burly in a burly bag or cage and throw it approx. where you will be casting your line to. If there is any current running (out going tide ) throw small handfuls of burly (use a mix like Shanemills suggested ) and cast into where you see your burly is going. Experiment with different mixes as different fish and waters will fire up on different mix's. Your catch rate will no doubt go up by asking questions and taking advice as no one gets anywhere by fishing the same way each trip and not getting results. Good luck on your next fishing trip.
