Bushwalking with dogs to a camping cave - suggestions ??

Hi all,
Myself and a friend are looking for bushwalks in State Forests where we can take our dogs and also head to a cave/overhang to spend the night. We are looking for places in a 100/200 klm radius of Nowra. Obviously there are tonnes of caves etc in The Budawangs but these are certainly not for dogs.
Any suggestions would be appreciated.
Thanks,
Tim
