Life Gillan is thought to have been born in 1873. She was born in the Glendonald area of the City of Ballarat. The NCW were not impressed that the Centenary Celebrations Council was an all male affair and they formed the Women's Centenary Council with Gillan as treasurer in 1933. The Women's Centenary Council published a Centenary Gift Book in 1934 and they constructed a memorial garden dedicated to pioneer women. and the register opened in Melbourne Town Hall on 24 March 1939. The NCW was to manage the initiative and more specifically Gillan who became the honorary registrar and "Minnie" Williamson who worked as the honorary secretary. The register was a success and over the course of the war 30,000 names were added. These women volunteered to work for the government in the evenings doing unpaid work to assist the war effort. The office was closed in 1944

Gillan was treasurer of the Victoria branch of the NCW until 1951.
