[3] The house, built in 1840 and extended in 1863, forms the central administration block for the College today, having been purchased by the Catholic Church using the Vatican's finances in 1929.

In further developments, the school purchased the remaining front terraces it was neighboured by, being preserved and renovated to serve as classroom and administrative spaces as three separate 'cottages'.

[4] The school's colours, being red, yellow and black were chosen for their iconic relation to the North Sydney Bears Rugby League team.

All teachers and administrative peoples were part of the Marist Brothers or another religious missionary group, and would receive funding for the school from the local parish church and parents.

Being beneficial to backpack weight, academic research and technological integration, laptops remain in use throughout the school; albeit in a BYOD (bring your own device) scheme.

[9] In 2015, following an extensive 10-year planning process, the multi-purpose 'Montagne Centre' was built on the fringe of the college campus, facilitating greater enrolment capacity and recreational activities.

In 2020, the college transitioned away from its traditional Latin motto of 'Respice Finem', replacing its past ubiquity on all school material with a slogan describing 'A Daring Faith', 'A Dynamic Education' and a 'Holistic Personhood'.

In 2021, with an additional variety of grants and other monetary support, the school erected several demountable structures at the once vacant block adjacent to Shaftsbury Road, accounting for further enrolment expansions.

Furthermore, an indigenous mural was placed on the face of the library building itself, representing the Wallumettagal people associated with the Ryde, Hunters Hill and Parramatta regions.

The Creative and Performing Arts rooms located in the A-block precinct was refurbished with new TV equipment and drones to support the college's ongoing MCETV initiative.

From the results garnered from these events, the 'Malloy Cup' is a trophy presented to the winning house at the conclusion of the school year for the aggregated sporting and academic achievements of pupils.

[16] Additionally, the college offers the opportunity for students to compete in chess, public speaking, debating, musical bands, and the Duke of Edinburgh's Award.

[18] On a triennial cycle, school staff and students part-take in the ceremonies of World Youth Day, an event coordinated by the Catholic Church to collate international communities of young adults to a singular venue within a given country.

With a cultural and religious group of students selected for travel, the college's representatives visit the significant sites of Marcellin Champagnat in France, whilst participating in viewing various sporting events across the western portions of the continent.

The cultural group often sends an association football and rugby union team to compete against local sporting academies and schools in the touring region.

[20] In a similar tradition, an 'Immersion Tour' is often organised, generally for students to visit a disadvantaged country or location within Australia for the purpose of humanitarian and missionary principles.

The college actively organises an annual 'Market Day', where the wider school community contributes consumer items for purchase in a marketplace-like environment to raise funding for a particular charitable or tangible cause.

Student representatives are often invited to participate in the City of Ryde's Granny Smith Festival Parade, raising publicity and awareness for the local region.

Under compliance with the New South Wales Education Standards Authority, Marist College Eastwood offers all subjects in the organisation's 'Category A' section; at minimum through a remote or distance learning model.

The former principal, Brother Patrick (Thomas Butler), was adversely named in the Royal Commission into Institutional Responses to Child Sexual Abuse.

[25] Marist College Eastwood is registered with the New South Wales Education Standards Authority, and has gradually improved its HSC result rankings over the last decade.
