With the date for our move down under getting closer and after seeing the You Tube clip posted by Jon, I've been doing a bit of research on the Bushwalking scene in Australia. What is immediately apparent is that it is very popular with Bushwalking clubs all over the place. There are 2 close to where we will be living in NSW and they offer a varied program of activities. As a given, there will be bike rides once a week, a mid week day walk and a overnighter twice a month.
Every club I looked at will also organise trips to NZ and the USA with the John Muir Trail being the most popular. The main forum seems to be this one Bushwalk Australia
Some of the post are quite interesting though and do include titles like 'Hunters accidentally shoot walker in NZ'.
