i think $200 is way to rich, $200 is not 100% mark-up for a 2-3inch fish its way over. i think $100 is reasonable for a 3 inch ish fish. its amazing how our native fish can sell for half the price overseas, but unfortunately that's just the way it is here in aus.
surely they cant be that easy to catch? they would be seasonal as well as probably need certain knowledge on where exactly to find them. hahaha thats a guess, maybe they are extremely abundant up north i don't know.
im also guessing it wouldnt be feasible to fishing for jardini's from bathurst. if it was on the way fair enough, but a deliberate trip would cost alot more than $200.
go for a drive down to syd, day trip would net you one for $100ish.
