The Sisterhood of International Peace was formed in Melbourne in 1915 'To promote mutual knowledge of each other by the women of different nations, goodwill and friendship, to study the causes - economics and moral - of war; and by every means in their power to bring the humanising influence of women to bear on the abolition of war, and the substitution of international justice and arbitration for irrational methods of violence.' The president was Lucy Paling, the secretary Janet Strong and corresponding secretaries Mabel Drummond and Eleanor Moore. Moore remained as secretary for many years.

Aside from its central object of abolishing war, WILPF in Australia has focussed on women's rights and Indigenous Australians' rights as well as working with projects for refugees in Australia and overseas.
