mcgrath50,
Yep do the Warragamba thing then follow the river back to Camden at 500ft contour flying it. I don't know what you fly, but it is very enjoyable in something like a Tigermoth. Open cockpit, green fields, low and slow (or rather fast for a tigermoth!), smell the fresh cut hay (or rather the horse poo from all the stables out that way). There is a nice little gorge and swimming hole on someones property out there! If you had a chopper on floats and owners permission looks it looks inviting from 500ft! Would be awesome in a Piper Cub as well I would imagine!
Cheers
