Hello Reg. I fish the Pine and Reddy reefs also..well i used to when i had something called time. I too love chasing the flatties in winter and find them really stacked in some places, yet i cannot find or rarely try to even over summer. Right now is a great time to net some of those prawns you say they are filling up on and take them out to those shallow reefs. Some really good snapper off Woody Pt and Margate around Feb and March and they cant resist those big live prawns
