I think Hiram Big will have to add something new to the front door of his mansion Quokka Terrace. When someone comes calling, he will be asked some very ordinary though slightly difficult questions. If the person answers the questions using aussie slang gibberish, instead of normal English, the person will be given a time limit in which to leave the premises. If the person does not leave, the laser defense system will burn that person to a crisp.
