I found the lnk to this site on another defence support site i belong to.
Its a TRI - Service site and it rocks!
Its Australian Defence Partners
http://s8.createphpbb.com/australiandefen/
It has both public boards and private boards (you can only access private after applying and admin accepting you)
The admin team is majority Army but they are a fantastic bunch who help out anyway they can for any of the services.
