 Carrathool Post Office opened on 20 June 1882.Carrathool notably is sign posted on its outskirts "population 99" and for many years we hoped to reach 100, however with droughts and children often moving to larger centres this figure may never have been reached.The above census figures for 2006 would not relate to the township of carrathool and would not have a higher population than its neighbouring township of Goolgowi.
