I spend a little time down that way from time to time seeing the relatives.The little blue lake has reddies, lots of small ones as well.Nelson River is nice but can get populated by danglers over the Xmas break.Piccinini Ponds is a camp site plus freshwater sink hole, the beach outlet often has mullet and salmon trout. I have seen solid Mulloway, schoolies and gummies caught here.The Break wall at Pt Macdonnell is a little difficult to fish but I have caught KG Whiting, Gar and the usual rock species. The jetty will hold KG Whiting as well, as well at times lots of mackerel and tommies.Blackfellow caves is a great spot for Bream, Mullet, Whiting.Carpenters Rocks (lighthouse beach side) will hold salmon, mullet and ST's. then on the shallow beach Gar can be found.That's all I can think off from the top of my head.
