Mary MacKillop (Saint Mary of the Cross) was an Australian nun who devoted her life to educating poor and rural children, founding schools and a new religious order that spread across Australia and New Zealand.

Who Mary MacKillop Was

  • Born in 1842 in Fitzroy, Melbourne, to Scottish immigrant parents.
  • Became a governess and teacher in Penola, South Australia, where she first focused on poor and Aboriginal children.
  • Took religious vows and the name “Mary of the Cross,” marking the start of her life as a religious sister.

What Mary MacKillop Did

  • Co‑founded the Sisters of St Joseph of the Sacred Heart with Fr Julian Tenison Woods in 1866, Australia’s first religious order founded in the country.
  • Opened the first St Joseph’s School in a converted stable at Penola to give free education to poor children, especially in remote areas.
  • Developed a school system and curriculum for parochial schools across South Australia focused on the rural poor.
  • Led the expansion of Josephite schools, convents and charitable institutions throughout Australia and New Zealand, providing education and welfare to thousands of children and families.

Key impacts

  • By her death in 1909, there were over 300 Sisters of St Joseph, more than 100 schools and over 12,000 students in their care.
  • The Josephites also opened orphanages, refuges for women in distress and other works for the underprivileged, living a deliberately poor and simple lifestyle.

Struggles and Courage

  • Faced opposition from some church authorities because the Josephites were run with “central government” by the sisters and insisted on serving the poorest, not wealthy parishes.
  • Was excommunicated for several months in 1871 in Adelaide after conflicts over control and discipline, but remained obedient and was later fully reinstated when the decision was reversed.
  • Travelled to Rome in 1873 to seek approval for the Order; officials confirmed the Josephites’ central governance and mission (with some modifications), and the Order received final approval in 1888.
  • Continued to lead and visit communities despite chronic ill health and a paralytic stroke in 1901, eventually leading from a wheelchair.

Sainthood and Legacy

  • Died on 8 August 1909 in Sydney; devotion to her life and example grew steadily afterward.
  • Recognised as a natural leader : strong‑willed, quietly determined, deeply religious yet practical and good‑humoured.
  • Canonised as a saint by Pope Benedict XVI on 17 October 2010, becoming Australia’s first canonised saint; her feast day is 8 August.
  • Today, countless Australians have been educated or cared for in institutions begun by the Sisters of St Joseph, continuing Mary MacKillop’s mission for the poor and isolated almost 150 years on.

In simple terms, what Mary MacKillop did was build a nationwide network of schools and charities so that poor and rural children “had a fair go” at life, even when powerful people stood in her way.
