Soon after their arrival the duo headed out for a jet boat cruise on Sydney Harbour. The pair are said to have asked the driver to allow "more water" into the craft. A spokeswoman for Oz Jet Boating said: "They wanted to get wetter - they said they don't have anything like it in America and thought it was hardcore."
However, when the boat docked at Pier One, around the corner from their hotel, the Park Hyatt, Stewart lost her cool. "She was just in a bad mood because of the photographers," the Courier Mail quoted a fan, whose request for a picture was refused, as saying.
The source went on: "She sprinted along the wharf trying to get away. She was swearing at them and tried running into a restaurant, but the door was locked." The informer added: "She was saying, Stop taking my picture."
