australia doesnt have a national motto. The states however do have state motto's :
Australian Capital Territory: For the Queen, the law and the people New South Wales: Orta recens quam pura nites (Latin, "Newly risen, how brightly you shine") Northern Territory: none Queensland: Audax at fidelis (Latin, "Bold but faithful") South Australia: none Tasmania: Ubertas et fidelitas (Latin, "Fertility and faithfulness") Victoria: Peace and prosperity Western Australia: none
"In God We Trust" and "E Pluribus Unum (Latin, "Out of many, one")" are national mottos of the United States.
Perhaps the writer needs to consult his or her high school history books.
