St John's Catholic Church, Campbelltown, Catholic church in Campbelltown, Australia

St John's Catholic Church is a brick structure built in Victorian Georgian style, positioned on Cordeaux Street with a symmetrical facade, tall windows, and detailed stonework. The architectural design displays careful craftsmanship in its decorative elements.

The structure was established in 1824 after James Bourke donated land for its construction. This founding marked an early phase in the development of religious infrastructure in the region.

The cemetery portion of James Bourke's 1824 land gift was consecrated on 27 December 1826, and burials there long preceded the church's completion. From 1886 the old church housed the Good Samaritan Sisters as St Patrick's Convent, a boarding and day school that ran until 1970. The building was returned largely to its 1830s form in 1984 with Heritage Conservation Fund money.

The grounds open for services on weekends and weekdays, with visitors able to attend scheduled gatherings and regular observances. It is helpful to check ahead for specific timing, as service times vary throughout the week.

The cemetery land was consecrated on 27 December 1826, two years after the foundation stone was laid. The church itself was not completed until 1841, and the first Mass had been offered there by Father Therry on 27 July 1834. From 1886 the old church served as St Patrick's Convent for the Good Samaritan Sisters, a boarding and day school, until 1970.
