No worries BOY-Z, hope it helps.
I have been following a plan of late and managed some really good catches of any between 6-40 grunter a session with another fisho this year(following a philosophy of only keeping those over 45cm) Fishing is a funny thing. Just when you think you have them sussed they contradict every logic and you come up empty handed.
Funny you mention the shorter rivers thing Mark as some of my best catches have been from the mouths of small tributaries. Some of the creeks north of Townsville have gravelly shoals just out from the mouths and I suspect that is were the majority of grunter feed and on certain occasions come into the creeks to feed and spawn. Don't know...just a theory but that is all fishing is really
