Hi Mike, quite a few fish grunt after capture, trevally are a notable one, also mulloway and gurnards are known for it (and maybe garfish too from memory?). I can't remember ever hearing it from flatties though.
Fishing in Canberra is going well, although only on the redfin front (still haven't caught a native yet). I caught my PB redfin of 41cm during the week, while trolling my faithful pink/black stumpjumper
EDIT Hi Glen, I've been trying to upload a picture, but keep getting the following error message:
