The leadership and management of Trinity Catholic College is the responsibility of the executive team. This group consists of the principal, assistant principal, Religious Education Coordinator (REC), director of studies and two campus directors. One campus director is responsible for the Regents Park campus, while the other is responsible for the Auburn site.

The principal, assistant principal, the REC, the director of studies and all coordinators of Key Learning Areas (KLA)spend time on both campuses.

There is a pastoral coordinator for each year group who takes primary responsibility for the welfare and progress of those students. An assistant pastoral coordinator and a team of pastoral care teachers assist the pastoral coordinator in this role.
