After the 2nd World War (1939 - 1945) there were numerous vocations to the priesthood and worldwide communications had made access available to Asian, African and South American people. So missions to Asia and Africa became attractive to the young men wishing to enter the priesthood. For this reason the Society decided to seek priestly vocations for missionary work in Africa from many parts of the world, including Australia . Archbishop Prendiville of Perth offered to accept the Society into the Archdiocese on the condition that it started a boys' secondary school in Beaconsfield/Hilton.
Land was obtained in York Street and Fr Elisha O'Shea SMA and Fr Martin Walsh SMA began the school in February 1964. In March 1964 Fr Richard Fitzgerald SMA succeeded the Oblate fathers and became parish priest of Beaconsfield.
