Early history and origins The
Sisters of Mercy opened St Joseph's School in 1883. The
Marist Brothers founded St Francis Xavier's College as a boys' school for the
Bunbury region in 1954. By the end of 1972, the enrolment had risen from 84 to 290. In 1955, Sacred Heart High School (opened 1899) merged with St Joseph's. In 1973 the
Bishop of Bunbury,
Myles McKeon, ordered the amalgamation of St Francis Xavier College (
Marist Brothers) and St Joseph’s School (
Mercy Sisters). The amalgamation of the two schools formed
Bunbury Catholic College.
As a second campus to BCC Our Lady of Mercy College was originally constructed as a second campus for
Bunbury Catholic College to “alleviate the enrolment pressures [on BCC] but also [to] open up more enrolment places for students in [the
Australind area]”. It was referred to as the Mercy Campus (with the original campus being known as the Marist Campus) and opened in 2015, catering for Years 7 through 9. On 5 July 2019, Rob Crothers was announced as the new principal of the school as Denise O'Meara retired from the role after 12 years. Crothers had previously been principal of
Nagle Catholic College since 2014.
As an independent school Signage around the campus was replaced in the week following the conclusion of lower-school classes in December 2019. The College became officially independent on 1 January 2020. The first classes as an independent school were held on 3 February 2020 for Years 7 and 12, with the first Year 8–11 classes held the following day. The school directed parents to keep their children at home beginning 27 March due to the ongoing
coronavirus pandemic. The College reopened for Year 11 and 12 students on 29 April, and in a limited capacity for students in other years. It resumed full operation on 8 May. == Campus ==
