By the wayside
Dean, I don't live in the area but hope to be visiting after Christmas, for around 10-14 days. I've read here that 7 mile beach has a CO area although I'm not sure that it is legal, just used by some. We will be staying nearby there so I hope to find out.
I walked along 7 mile beach when I was there recently, walked a long way, saw no nudes, the weather was OK but not great. I found some isolated places in the dunes and enjoyed some sun but did not walk along the beach naked. A woman did walk along the dunes and see me and she just smiled and kept walking, she wasn't bothered so maybe seeing nudes along there is common, I don't know.
when I lived around that area there was a track just south of the main cross roads but only a small area to park, it was mainly frequented by fisherman and maybe half a dozen nudies, the beach is also very windswept so you need to seek some protection. closer to shoalhaven heads is difficult due to the crowded beach, further south is a better option
