For those in NSW the Wollondilly River is quite close to Wombeyan Caves - inland from Mittagong and about halfway between Sydney and Canberra. The site is managed by a caretaker and his wife who have a small office and shop with very limited basic supplies available. Other than that there is a hot shower (that we didn't use) and toilets on site that are a pump flush porta-loo design.
We drove in from Yass, to Goulburn, through Taralga, and onto Wombeyan Caves Road. This leads to the office where we met the caretaker, had a bit of a chat and were directed to our site, which was across the river from the office.
