De La Salle Caringbah was established in 1958 as a Years 5–10 boys school and eventually settled to educate Year 7–10 students. Our Lady of Mercy College, Burraneer Bay is the Years 7–10 girls school. Students from both schools then transfer to
De La Salle Catholic College Cronulla for Years 11–12. From 2024, both De La Salle Caringbah and Our Lady of Mercy Burraneer will expand to offer Year 11 classes with both schools to be fully Years 7–12 from 2025. Students will still have the transfer to study at De La Salle Cronulla if they wish a co-educational education in their senior years with that school to be fully Year 7–12 from 2027. De La Salle Caringbah was founded after there was thought to be a need for a Catholic Boys High School in the area. On 28 January 1958, 65 students began the first class in the basement of the old Our Lady of Fatima Church. By 1963 the current college building was built. == Principals ==
