In 1922, Munro held the first
Country Women's Association (CWA) conference over three days during the
Sydney Royal Easter Show and was subsequently elected as its president. She travelled throughout New South Wales and
Queensland to help form branches of the association. By 1923, sixty-eight branches, seventeen restrooms for mothers and children, two seaside homes, and maternity centres in many towns had been established. She helped found a rest-room in
Bingara in 1924 as well as the first country baby health centre in
Moree. By 1926, when she retired due to illness, there were 100 CWA branches with a membership of 4,500. == Other charitable works ==
