A little gold mine I worked at in QLD used to have their admin office on a public road. We used to laugh our arses off when grey nomads would just drop in and think someone would give them a tour of the mine. It's not an amusement park. No offense. No harm in trying but don't hold your breath. You need to be inducted to even walk inside the gate so unless someone is feeling very generous with their time I'd say it's unlikely.
