G'day Brian,
1: I can recommend the camp stay and baffle bobs. Stayed at both. I prefered the camp stay, but the ramp is bigger/better at baffle bob's. The camp stay has all the gear laid on if you need it. Just bring food & beer..... there was something else..... oh yes, fishin' gear
2: Don't know, but you could reasonably expect bream, flathead, jacks etc.
3: Bring it all If you're going to stay in the creek, then 15kg may be a touch overgunned for all but Jacks in the sticks.
4: Yes
5:As with any mangrove/estuary type area, at times they'll eat ya alive! If he suffers, bring the appropriate creams etc.
have fun, it's a top spot
cheers,
Owen
