The college, founded by the Goulburn Catholic Diocese in 1874, had been operated by the Christian Brothers from 1897[1] until its closure.

The amalgamation was essentially due to declining enrolments, linked in part to Goulburn's decline in population and importance as a regional centre, a process which has been occurring gradually over the past century, particularly after the founding of Canberra in 1913.

The brothers continued to operate the boys' boarding residence but due to a lack of resources this facility was amalgamated with the girls' boarding school from North Goulburn at the old St. Patrick's campus in 2006.

The responsibility for the boarding facilities transferred at this time from the brothers back to the now Archdiocese through the Catholic Education Office.

After the amalgamation, the teacher and professional historian Dr Bollen published a history of the college.
