I sometimes head down to a point around 50km south of Sarina for a drive. You turn left off the Bruce Hwy, travel down a dirt road between prawn farms, go through a gate and get to this spot which has a windy side (exposed to the SEerlies) and a calm side that is sheltered by the point and faces into a large shallow bay.
On the windy side, there is a great beach which has a reef trending NE-SW almost exposed as low tide creating a fairly flat water lagoon between it and the beach. The reef extends at least 500m. Looks to be a beam to broad reach in one direction and a beam to close reach in the other in the SE wind.
There are the usual Nth Qld negatives - stingers in summer and the calm side has mangroves and looks like a great place for crocs. Camping is free but there are no facilities.
