The book Vertical 2nd edition (2007) by Al Warild is the gold standard caving manual in Australia. It used to be available free online at, but this domain has expired. Because it is such a useful text, I have uploaded it here so that NUCC members have access to it. I will remove it if the domain becomes active again, or this turns out to be sketchy with regards to copyright.

Obviously, this book remains the sole copyright of the author

NUCC does not endorse the techniques explained in this book, and you attempt it solely at your own risk. We do not use all the techniques described in the book, and some would be dangerous if attempted by the average sport caver without expert guidance
