Mack attended Sydney Girls High School where she met Ethel Turner.
By the time she was ready for secondary school, the family had taken up residence in Sydney. From 1898 until 1901, Mack wrote "A Woman"s Letter" for The Bulletin. Her first novel was published in 1896 and her only collection of poetry in 1901.
Following this she travelled to England and Europe and did not return to Australia until 1916.
In 1914 when war broke out Louise Mack was in Belgium where she continued to work as the first woman war correspondent 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.

Returning to Australia in 1916, Mack gave a series of lectures about her war experiences. Mack frequently wrote for The Sydney Morning Herald, the Bulletin and other newspapers and magazines.
On 1 September 1924 Louise married 33-year-old Allen Illingworth Leyland (d1932).
She died in Mosman, New South Wales in 1935.
