A visit today to the Symonston Aboriginal Quarry site in Canberra. I haven't been here in 8 years so I was interested in seeing its condition after that time. Apart from a bit of rubbish and a covering of dead pine needles it does not appear to have changed although, from memory, there was more "chert" flakes years ago.
Unless you were specifically researching the site its not a site you would just stumble upon. It is very close to a major industrial/commercial development. I took some video..
