That link you gave Tony is ok and is one of the spots i would of shown you, it is also the easiest or most straight forward to get to, BUT as such it can be or could be a place where some young blokes might come at night for a bit of circle work (im not sure never camped in that spot).
I have seen a few families camped just to the left of that clearing as you see it on the map you provided, much smaller clearing and a little more out of the way.
you will also see a few other clearings on you travels through out the day and any of those can be used if you choose.
my favourite spot (maybe not for others ) is the smallest area is down by the river at the "boat ramp" this track is by far the most secluded and least likely to have any other traffic.
It is off a track that leads directly off Meryla Rd, it has a side trail around a gate that stacks of people use, i believe the gate is only there to stop people taking boats down to the river, they have never blocked off the side track as you will need to be in 4wd to get through the first 50m
If you look at the link below you will see that there is also a side track about 200m off the road that leads to another clearing, this would be ideal if there ends up being a few of you as the spot down by the river is small and last time i saw it getting smaller, but fro a few swags and a tent i would stay down there no probs others may think not, i like to be near the river and prob would be up all night trying to catch some sort of fish from the river.
Anyway when you look at the map follow the trail to the water and you will see a small clearing.

All the other spots are hard to point out on the map due to the trees, so they really are best to be shown on the day, unfortunately i wont be able to do that so those few i pointed out are prob the best i can do with out actually being there.
The other alternative is to drop down the hill after you come out at Fitzroy Falls to Kangaroo Valley and stay out off Bendeela Rd, if not there are two van parks down there.
Or duck back to Bundanoon and camp here, depending on where you end up coming out its not that far.
