Margaret Joan Holmes AM (née Read; 24 January 1909 – 10 September 2009) was an Australian peace activist, particularly during the Vietnam War and as part of the Anglican Pacifist Fellowship.
She founded the New South Wales branch of the Women's International League for Peace and Freedom in 1960, and in 2001 was made a Member of the Order of Australia for her services to the community.
At the beginning of World War II, the Holmeses established the "50-50 Club", a weekly social evening where "new Australians" could get to know the locals and better integrate into their new society.
[5] Her trip included travelling to Austria for an IFOR conference, to Russia (where she delivered smuggled bibles to the Moscow Baptist Church) and to India (at the invitation of Sushila Nayar, whom she had met at the WILPF congress).
Her biography, Margaret Holmes: The Life and Times of an Australian Peace Campaigner, written by Michelle Cavanagh, was published in 2006.
