Mearzie,
I will probably regret posting this (you never know who will see it) but there is excellent cod fishing in the Peel down from the BMX track at North Tamworth. They tend to be a bit thin in winter but they are still there. If you get some Jackalls then take them down there and target the carp with them. They absolutely smash them when in the right mood!!! During winter your best bet would be the Manilla River down from Upper Manilla for BIG cod. If you do get one please let it go as I feel like I know every one of them!!! The Paradise Caravan Park does have good fishing at times but if you walk upstream for about 4 hours i.e. Nemingha, then it starts to get really good on the days around a full moon.
Hope this helps.
Wardy.
