Hi Jack_attack,
There is a group already stocking the Caboolture River. They have already been stocking mullet & bass I think. I don't personally know anyone from this group so I'd suggest you contact the Freshwater Fishing & Stocking Assn of Qld (FFSAQ) for any help in a contact or setting up a new stocking group. email ffsaq@logicworld.com.au or visit their website at ffsaq.ausfish.com.au
Cheers,
Fitzy..
