Actually, Charlie Boorman knocked on the door of my room in the Cairns Hilton last week, but realised he had chosen the wrong room when I answered the door.
I had seen him briefly in the Exec Lounge the night before and had read that he was in Cairns on some R&R before going up to Japan, so I wished him all the best. He looked a little bemused as the person he was meant to find walked up from their room, two door up.
