But when the vast Tipperary Station in the northern territory changed hands a few months ago, the new owners suddenly found themselves in possession of some rather unusual property � 2,200 exotic animals mostly from the wilds of Africa, all bought by the previous owner, millionaire developer Warren Anderson, to stock his own private zoo. Among them rhinoceros, giraffes, zebras and hippopotami, to name just a few.
