You Blue Mtns boys should keep across the announcements about Jambo 2012 because its going to be held in your back yard!
http://www.jeepjamboree2012.com.au/
The site has been selected and booked so watch for the announcement very soon on the website. I met someone here will guess it, just think about where you would want to accomodate hundreds of people and their Jeeps in the Blue Mtns in a bush camping setting?
Cheers
