Well, I've been and gone and went and done it! Booked Australian Adventure plus NZ add on for April 2008. My daughter is in Sydney and for my 60th birthday has given me a gift certificate to climb THE BRIDGE. can't wait. My only concern, however, is that i am now severely deaf and admittedly lost some of my bottle, but nothing ventured, nothing gained. Anyone out there doing this trip. Love to hear from you.
