Joyce is a muppet put there by Dixon to continue his legacy of talking down the airline so he and his mates (including Singleton) could buy it for peanuts and raid the $3.5 billion piggybank. Joyce has turned on his "mates" and made it more difficult for them to do that. Joyce was always going to be the fall guy and Singleton wouldn't sweat one second on publicly shafting Joyce, as Joyce's head was always intended to be the one going up on a stick when Qantas fails.
