Benny grew up on the family"s sheep station "Springfield", located near Stansbury, Yorke Peninsula. She married her cousin, solicitor Benjamin Benny (21 October 1869 – 10 February 1935), eldest son of the Reverend George Benny, on 16 July 1896 and moved to Adelaide where he worked.
She was elected to the Brighton Council (now City of Holdfast Bay) in 1919. Benny was active in a range of community and political organisations and during the First World War was the Honorary Secretary of the Seacliff Cheer-up Society. During this time Benny argued strongly for equality of divorce for women, which became law in South Australia in 1918.
Believing that there was work to be done in the area that only a woman could do, she was elected to the newly created Seacliff ward on 22 December 1919.
