Trinity Catholic College, Auburn

Trinity Catholic College Auburn is a dual-campus independent Roman Catholic co-educational secondary day school, located in the inner western suburbs of Auburn and Regents Park, in Sydney, New South Wales, Australia. Students in Years 7 and 8 are located at the Regents Park campus, and students from Years 9 to 12 are located at the Auburn campus. The college follows the religious tradition of the Marist Brothers, founded in 1817 by French priest and saint Marcellin Champagnat.

History
Trinity Catholic College was founded in 1995 from an amalgamation of three schools: Benedict College, Auburn, St John's Regional College for Girls, Auburn and St Peter Chanel Girls’ High, Regents Park. The Sydney Archdiocesan Catholic Schools Board decided to constitute a single new co-educational College to operate on two campuses in 1992.

The tradition of the Marist Brothers was established in 1942 with the foundation of a boys’ school at Auburn, which eventually became the senior Secondary school of the district, Benedict College. The Sisters of Charity, the first religious sisters to work in Australia, began a school at Auburn in 1893, which became St John's Regional College for Girls. The inspiration of St Mary of the Cross as one of the college's saints was handed down in St Peter Chanel Girls’ High at Regents Park, founded in 1953 by the Sisters of St Joseph.
