As the crow flies 10kms from Newnes is another old shale oil town Glen Davis. It is however 100 kms by road. It is quite a remote tiny remnant of a town nestled in glorious country of the Capertee Valley. There are a few houses and a small boutique hotel. It would be a great place to stay for the weekend. If you don't want to afford the hotel tarrif, nearby there is a free camping ground - a bit of dirt patch but it has facilities.
There are shale oil ruins here too but in private land. I haven't managed to get out there for one of their Saturday tours yet.
During the Christmas break I will add Glen Davis to 100 towns, and Glen Alice as a locality because there is just a community hall there.
P.S. I am having my cataract operation tomorrow.
