This is the Nerve test on the hike to the Pinnacle, halls Gap, The Grampians. I did this when I was a kid. I don't recall exactly how high it was and you cannot appreciate it from this video, but it is definitely high.
@Thevy29 I would not want to walk that if it were more than three feet off the ground, let alone however high that is. I would be so nervous I would puke.
