Britain's Queen Elizabeth II (R) and Prince Philip wave goodbye as they board their flight at Perth International Airport following their 10-day visit to Australia on October 29, 2011. The queen wrapped up an immensely successful tour of Australia in which tens of thousands flocked to catch a glimpse of their monarch, perhaps for the last time.
