Fishin_Dan,
Next time checkout Jacksons Creek, which is outside Kedron-Brook to the right. #Though you'll need to go out of Kedron-Brook a bit before turning south and then back into Jacksons Creek (see pic below).
Jacksons Creek has good bream, flathead and the occasional Jack.
Suggest you enjoy this creek soon, as I was speaking to Brisbane Airports Corp last week and they are planning to put the new second runway on the Jacksons Creek side of the airport, which will have some affect on the creek at some point.
I've also spent a bit of time flicking lures at the mangroves down along the southern side of Kedron-Brook, with good success. #Some very good lizards to be caught on the right tides/days.
Cheers,
Gigantor
