On 27 June 2018 at a symposium for parents, parishioners and senior leaders, it was announced that the North Sydney Catholic School Network's Marist Catholic College North Shore and neighbouring co-ed primary school St Mary's would combine to become a new North Sydney Educational Precinct. This new precinct named Marist Catholic College North Shore would consist of two campuses which would offer students stage-specific contemporary learning spaces and provide a seamless curriculum pathway from Kindergarten to Year 12. The primary education would continue on the St Mary's Catholic Primary School campus under the shortened campus name of St Mary's, whilst secondary learning would take place on the former Marist Catholic College North Shore campus now named La Valla campus.
