Mount Carmel Catholic College was first initiated in 1983/84 by a committee of parishioners located in Ingleburn and Macquarie Fields.

The goal of this committee was to establish a Catholic secondary school for the northern part of the Macarthur region.

[3] After negotiations with the Carmelite Fathers the site was chosen in Varroville near St Andrews Road and Spitfire Drive.

Following a federal building grant, construction on the La Valla Trades Skills Centre began in 2014.

At the end of Semester 1 of Year 10, students will receive an eligibility criteria for all courses offered at the College based on their Semester 1 academic results and effort grades to inform their subject selection decisions, as there are grade prerequisites for entry into certain HSC courses.

These include, but are not limited to: A number of senior students also take part in the annual immersions to work in underprivileged communities.

Students at Mount Carmel are placed into one of four houses which they will remain in for the entirety of the junior school (Years 7–10).

The junior school follows a horizontal system in which students are placed in pastoral classes (homerooms) with their own year group.

Mount Carmel is shaped by both the Marist and Carmelite charisms, creating a unique Catholic identity.

Our Lady of Mount Carmel Parish serves the local Catholic community and is located adjacent to the College grounds at 193 St Andrews Road, Varroville.

St Marcellin Champagnat, founder of the Marist Brothers, is the patron saint of Mount Carmel.

Students are also encouraged to partake in numerous religious and spirituality opportunities throughout the school year, both at the College and in the wider community.

For instance, Mount Carmel holds an annual recycling competition, and the most successful house receives the Sustainability Cup.

Following a selection process involving interviews and speeches, the entire house votes for their preferred candidates.

It recognises students who embody the qualities of St Marcellin and the Mount Carmel spirit every day.

Yearly celebrations and important festivities include: Mount Carmel has a strong sporting tradition and culture.

Mount Carmel also offers pathways for students to progress into New South Wales Combined Catholic Colleges (NSWCCC), Diocesan and Representative (regional, state, etc.)

The establishment of the Alumni has resulted from the strong sense of family and community that is part of the Marist charism and which forms the fabric of the College.

The Whitfield Library aims to satisfy the 21st Century learning, recreational and literary needs of its information consumers through service that exceeds expectations in physical and virtual environments.

In the centre of the library is the atrium, a covered outdoor study area, with the statue of St Marcellin Champagnat.

The College gathers in the hall to celebrate mass, participate in assemblies, awards ceremonies and other whole school events.

A number of creative arts endeavours, such as drama, music and dance performances are also held in the Champagnat Centre.

Key features include the mezzanine level, and the mural on the rear wall, illustrating the school's philosophy of 'Marcellin inspired, Christ centred' learning.

Named in honour of Mary, mother of Jesus, as an homage to the College's Carmelite charism, it is used for gatherings of small crowds, liturgies, silent prayer and reflection.
