Hi Wazza,
You’ll probably get some more helpful and detailed replies from others on here, but for what it is worth I took the family up there a couple of times a few years ago. Nice spot. Very quiet. The Burrum River is quite wide at the heads. Your tinny will be able to go anywhere in the river. Plenty of mangroves so I would take some pots. Also lots of rock ledges, deep bends and holes for casting lures or baits. I was told there was good fishing outside the heads but we were just using a hire boat so couldn’t venture out there. I imagine mangrove jack would inhabit further up the river and you can get all the usual estuarine species. Good luck.
