Where in the Australian Capital Territory is this benchmark (BM) survey marker plate (general location say within 1 km)?

Who’s into Geocaching, do you know the precise location?
Clues: Space, STS, year 1981 and the number 26 🙂
Answer: At the former Orroral Valley Tracking Station operated by NASA. The benchmark plate is at the base of the former 26 metre radio telescope once used to communicate with the Space Shuttle Columbia. The 26m antenna is now located at the Mount Pleasant Radio Observatory, Tasmania operated by the University of Tasmania.
Of interest to some radio amateurs will be the base of the former WWV antenna and mast
Justin VK7TW was so close. Here is a photo of the former NASA lunar laser ranging station 1.7 km south-west, at a bearing of 240 degrees from the survey plate.
