The College also includes a small country campus in Strath Creek which is used as a retreat and by visiting class groups.

A growing population in the area made it clear that a fully functioning secondary school would soon be needed and the College at Epping was planned and building commenced in 1966.

[2] The name, St Monica's, was bestowed on the College by Archbishop Simonds in 1966 but it was not until February 1967 that the completed buildings in Davisson Street were officially blessed and opened by Bishop Moran.

The school has received criticism for insisting that students with a deceased or unavailable parent may not use their tickets for a sibling or other member of their support network.

The school has sports facilities for Australian rules football, Volleyball, athletics, swimming, cross country running, Basketball, tennis, golf and Futsal.
