Is anyone know about Jervis Bay carravan camp??

Hi everyone.
Do you have any plan after the semester?
My husband and me are considering to go somewhere close from Sydney, and I found out 'Jervis Bay'.
It is very famous holiday place for everyone.
But do you have any idea for accommodation here?
I want to stay caravan park, but every website give rough ideas only.
Pleas give me some idea if anyone have caravan park experience in Jervis Bay.
Thanks.
