Hanging Rock is a good choice. I'll make plans to be there.
I was going to add: Noojee has Toorongo River: very scenic, especially the bridge over the Toorongo, two waterfalls, lush rainforest with a stream trickling through it and a great place to have a picnic. Excellent coffee from the Red Parrot café in town, or brew your own, camp-style.
But please: let's not just stand around idly talking non-stop. This should be about photography, exchanging skills and eyeballing bodies — ahem, cameras, I mean! Coffee and munchies later!
