John Bede Polding, a Benedictine monk, was Sydney's first Catholic bishop (and then archbishop) from 1835 to 1877. Polding requested a community of nuns be sent to the colony and five Irish Sisters of Charity arrived in 1838. The sisters set about pastoral care in a women's prison and began visiting hospitals and schools and establishing employment for convict women. The sisters went on to establish hospitals in four of the eastern states, beginning with St Vincent's Hospital, Sydney in 1857 as a free hospital for all people, but especially for the poor. At Polding's request, the Christian Brothers arrived in Sydney in 1843 to assist in schools. In 1857, Polding founded an Australian order of nuns in the Benedictine tradition – the Sisters of the Good Samaritan – to work in education and social work. While Polding was in office, construction began on the ambitious Gothic Revival designs for St Patrick's Cathedral, Melbourne and the final St Mary's Cathedral in Sydney.
