Personally I prefer Dorrigo, but ONLY if there's no chance of a S.E. Along the beach track at Dorrigo is brilliant. There's another track that runs parallel to this and is more protected. If there's a chance of wind, we usually go there. If you don't want to be near water, there's also the top side to Dorrigo. Dorrigo is the only spot with surf.
Natone is a great spot also. If it's soft, it can be a slog to enter. It's a lot more protected from the wind. It's just past the point of surf meeting the passage. Not the best swimming at low tide.
Beagle is a good spot to camp, really protected from the wind and some absolute cracking spots to camp right on the beach with brilliant views. On hot days, you'll have third degree burns to your feet by the time you cross the soft sand to the water. Definately the best campsites IMHO, but no surf and on low tide not the best swimming. If you have little kids, there's usually some ripper gutters left at low tide with up to 3/4m of water left in them around that part of the beach.
If Sarawak was the only place left to camp, I'd come back home. We generally get smashed by sandflies there. That area generally has no apeal to me anyhow.
There's also another ripper spot, it's only very small but brilliant. Between The Oaks and Dorrigo. It's an unsigned entrance, but has a signed exit. A little sign "One way, exit only" or something. Entrance is about 100m south of there. It's right on the surf beach, but again it's sucks arse in SE winds.
The Oaks is the first spot you'll come to. It's brilliant on still winters days. There's no shade and this time of year there's every chance of being absolutely hammered by wind and sand. We have set up there a few times in winter and it's awesome.
You'll get a camper into any of them. Natone is probably the softest, but at times we drive in and out in 2wd. Dorrigo can be soft. There's a hard left at the end of the beach track that gets soft and chopped up. After rain, again 2wd in and out of there. Beagle is very easy, Sarawak may as well be asphalt.
