Mary Immaculate High School originally opened its doors in 1987 following the reorganisation of Catholic Education. Prior to this the school was named Archbishop Mostyn which had existed since 1963. 


Our Mission is to be a Catholic School which promotes positive relationships founded on the gospel values of respect, care, compassion and love. 

Mary Immaculate is a faith school which seeks to promote Christian values to the young people in our care. While priority of places is allocated to Catholic families, the school is open to families of any faith and those of no faith.  

We firmly believe that each individual can discover, develop and achieve their full potential to take their place in our ever-changing world. 

Our core purpose is to:


“achieve the best for all”

This philosophy is at the heart of everything we aspire to do for each member of our community.
