Chanel College was established in 1966 to serve the youth of Gladstone district for their secondary schooling. The opening year saw an enrolment of twenty-three boys and girls in Year 8. They were accommodated on the site of the Star of the Sea Church and School at the corner of Goondoon and Herbert Streets.
The following year, 1967, saw the College move to its present site. Stella Maris College was established to become the girls’ section of the Catholic High School under the guidance of the Sisters of Mercy. The classes were co-educational.
With the arrival of the first Marist Brothers in 1968, Chanel College was founded as the boys’ section of the Catholic High School. As time went on, both schools amalgamated under the name of Gladstone Catholic High School. In 1985, Saint Peter Chanel was officially adopted as Patron of the College which then took the name of Chanel College.
