Hi Rick,
To my knowledge nothing at Wallacia anymore, although I did see some Trikes operating out of a small strip on a property near Kemps Creek a few months back. I live about 10 minutes from Camden now but originally from the Mountains myself, would recommend the Oaks, as far as GA goes the drive to Bathurst might be worthwhile for you. Lots of great cafe's and restaurants in the mountains as well as plenty of other activities up there!
Enjoy.
