Shoalhaven: See
Shoalhaven has some of the whitest beaches anywhere in the world and is often compared with the Whitsundays Islands, Jervis Bay and Currarong. It may not compare with Cape Le Grand National Park in WA, but it's still very white.
For those that are interested in planes and military aviation, the Fleet Air Arm Museum in Nowra may be of great interest displaying numerous aircraft and helicopters such as the GAF Jindivik, which is a pilotless target aircraft.
