The Diocese of Melbourne was created in 1848 out of territory of the then Sydney archdiocese, with James Alipius Goold as its first bishop. The Catholic population of the colony was 18,000 in 1851 and had grown to 88,000 by 1857 as a result of the gold rush. James Goold was also instrumental in setting up many Catholic schools in the diocese and in introducing several religious orders devoted to education and works of charity, including the Society of Jesus, the Christian Brothers, the Sisters of Mercy, the Good Shepherd Nuns, the Presentation Sisters, the Faithful Companions of Jesus and the Little Sisters of the Poor.
