The Turpentine Tramway - Herons Creek, NSW, Australia - Australian Historical Markers on Waymarking.com
From the above website, which appears to be a geo caching website.
"As I recall, when I was young, I remember seeing the remains of the tramline that ran from the Camden Haven River to Herons Creek, on the east side of Herons Creek Road. It passed about 50 feet to the east from our homestead at 316 Herons Creek Road. It then went south to the bottom of the first gully where it crossed to the west side of Herons Creek Road."
