​​​San Sisto was established by the Dominican Sisters of Eastern Australia and the Solomons in 1961.  While the college is now part of the Brisbane Catholic Education system, it is still a school ‘in the Dominican tradition’ where the ​Dominican charism is cherished.  San Sisto maintains strong relationships with the Dominican Sisters of Eastern Australia and the Solomons and with their secondary schools, Santa Sabina in Sydney and Siena in Melbourne, as well as many other schools in the Dominican tradition. The Dominican motto of 'Veritas' is part of our 800 year old heritage.​

Our students attend Common Ground, a conference for students from Dominican schools which is held biennially. Staff members attend the Dominican Education Conference, also held biennially and are able to undertake a Dominican Pilgrimage through Spain, France and Italy, offered at regular intervals.  The Principal and, on occasion, other members of the college leadership team, attend meetings of the Dominican Education Network.

Together with St Martin’s Primary School, also established by the Dominican Sisters of Eastern Australia and the Solomons, San Sisto celebrates Dominican Family Day each year on a date close to St Dominic’s Feast Day.

The college supports the work of Dominicans in the Solomon Islands and South Africa and of the Dominican Sisters of the Rosary in Timor L’este.
