Mater Christi College is an independent Roman Catholic secondary school for girls located in the eastern Melbourne suburb of Belgrave, Victoria, Australia.

Mother Mary Olivera, Superior General of the Good Samaritan Order of the Catholic Church declared in 1962, “Let’s build a boarding school on top of the hill in Belgrave".

[1] Subsequently, the school was founded by the Sisters of the Good Samaritan religious order in 1963 outside Belgrave, overlooking the Dandenong Ranges of Victoria.

Six Good Samaritan Sisters initially instructed 62 female students, offering an academic education, "based on the principles of Benedictine values".

[3] Sunny Siesta was on the 90 degree turn at the top of Bayview Road and was where the first sisters established their convent in May 1962.
