Sylvester Stallone has had his luxury room at the Park Hyatt Sydney hotel and his private jet searched by Australian customs officials. The event follows a search of luggage belonging to his entourage in which it is alleged that prohibited substances were being carried, possibly steroids. In Australia, the unlicensed importation of a wide range of steroids and performance-enhancing substances for sporting use is prohibited. Stallone was in Australia to attend the premiere of his latest film, Rocky Balboa.
