Stringy, you've been to Jervis Bay and I haven't, so you obviously know the locale better than I do, but camping at Currarong seems like a less flexible option to me.
It is a 15 km sail from Currarong to the entrance to Jervis Bay and if this article
is anything to go by, conditions can be very similar to those we encountered leaving Port Stephens. The thing is, if we are camped at Currarong and the swell is up, we have no option but to tackle the rough seas.
If we are camped within Jervis Bay, we have the option to explore the coast outside if conditions are favourable, or to explore within the Bay if they aren't.
Looking at the maps, the approximate distances to various points are:
Currambene Creek to Honeymoon Bay: 10 km
Currarong to Honeymoon Bay: 21 km
Currambene Creek to Bowen Island: 12 km
Currarong to Bowen Island: 18.5 km
Bowen Island or Hole-in-the-Wall would obviously be the most flexible place to camp and this may be do-able with hammocks, but I really think you guys will regret it if you attempt it without adequate undercovers.
I'm not particularly attached to it, but it seems to me that Currambene Creek may be the least worst option.
Of course, we always have the option to load the boats on the cars each day and drive to the most favourable launch points.
