Born in Tasmania in a family of Wesleyan minister and brought up in Sydney, Louise Mack attended Sydney Girls High School and after it chose a literature life track, having realized herself as a novelist, journalist and poet. She wrote "A Woman's Letter" for The Bulletin, her first novel was published in 1896 and her only collection of poetry in 1901. But the most surprising part of her career was working as a war correspondent, a job that no other woman in the world had taken before.

Up until the 1st World War Luoise was travelling to Europe, and when in 1914 war broke out she was in Belgium. Instead of getting back home she continued working as a war correspondent (the first female one ever) for the Evening News and the London Daily Mail. Her eye-witness account of the German invasion of Antwerp and her adventures — A Woman's Experiences in the Great War— was published in 1915. In 1916 she returned to Australia and gave a series of lectures about her war experiences. Afterwards she frequently wrote for The Sydney Morning Herald, the Bulletin and other newspapers and magazines.
