I Just got back from 3 weeks teaching Kitesurfing Lord Howe. Thanks to Kite Republic and David Gardiner, my host and mate on the Island.
This Video sums it up
If you are thinking of going to Lord Howe I recommend you get in touch with Dave (
http://lordhowekitesurf.com/) He offers 'Hosting'- primarily gear transportation around the island depending on wind direction.
Cleanest water i have ever seen, Strong wind, nice waves, abundant wildlife, Great hospitality from the locals. A trip i'll never forget.
