Moore was the daughter of George Varian Walshe, a clerk in the General Post Office, and Edith Marian Walshe nee Meux-Smith. Much of her early life was spent in France, Algeria and Corsica. Moore claimed to have travelled widely, living in Spain for seven years and visiting cathedral towns with her uncle, a well known English painter.
On 14 August 1913 she married John Irwin Moore, an Australian born Sub-Lieutenant in the Royal Navy. Their only child, Jim, was born in Gosport, England on 4 September 1916. She travelled to Australia in 1919 to be with her husband who was bringing HMS Swordsman to join the Royal Australian Navy. In 1920 they returned to England and came out again, arriving in Melbourne on 24 August 1924.
Moore's husband subsequently returned to England, leaving his wife and child with a small remittance. She wrote prolifically to support them - poetry, historical articles and journalistic pieces and was consistently published in the Sydney Morning Herald and Le Courier Australien. In 1936 Moore became 'travelling publicity officer' for Holyman Airways, forerunner to Australian National Airways and wrote numerous articles about air travel. In 1935 the French Ministry/Academy conferred on her its Academic Palms, as an Officier d'Academie for her literary services including the promotion of France and the French language. Moore also received the Free French Service Medal and was made a Member of Honor of the Free French Soldiers' Association. She was a founder and president of the Friends of France Association and an Honorary Citizen of Le Bresse.
Moore was known to Mary Gilmore (q.v.).
