Mount Saint Joseph, Milperra (commonly MSJ) is a Catholic girls’ (Years 7 to 12) school located in Milperra, New South Wales in Australia. Founded in 1960, the school is based on the values and spirit of Mary MacKillop. It is established under the auspices of the Sisters of St Joseph, and administered through the Board of Directors.
In 1959 Father Landers (Panania) and Father Carr (Revesby) accompanied Mother Leone Ryan, the Superior of the Sisters of St Joseph, in search of a suitable site for a new girls’ high school in western Sydney. At this time the population of the area was increasing rapidly and the parishes were unable to meet the costs of building such a school. The search ended with the purchase of the land on which the school now stands. The land was classified as Green Belt, so permission had to be sought and duly granted from the councils concerned. A school was built and in 1960, girls from the surrounding parish schools began their secondary education at Milperra. Since then, the Congregation of the Sisters of St Joseph has provided the necessary support for the ongoing development of the school.
On 20 April 1989, the Mount St Joseph School Board was instituted following the incorporation of the school as Mount Saint Joseph Milperra Ltd.
MSJ offers a range of curriculum choices ranging from UAI level HSC courses, through to VET courses supported by the National Training Framework.
