As a Catholic parish primary school, Holy Rosary has a history that is rich in tradition and is bound together in the spirit of community. We acknowledge that we are part of the faith journey of our parish community and that this journey will continue well on into the future.

Holy Rosary Catholic School is situated in the Hobart suburb of Claremont, famous for the Cadbury's Chocolate Factory. Holy Rosary Catholic School first opened its doors in 1961, over 50 years ago, with 37 children and two staff members. The school facilities consisted of two classrooms and staff area. Today some of the present students are the descendants of those early initial school families.

The Dominican Sisters were commissioned to take charge of the new school and so it was that Sr. Gabriel (Principal) and Sr. Catherine Mary arrived in Tasmania and with little in the way of resources and finances began to educate the children of the Parish of St. Bernard’s.

The school was founded with a view of providing a Catholic education to the children of St. Bernard's Parish. There has been a long and proud history of being a community minded school, providing particularly for the needs of students from marginalised backgrounds. Holy Rosary is a school that prides itself on the spirit of social justice that permeates through all aspects of the school community.

In 1975 it was announced that only one of the Dominican Sisters would remain at Holy Rosary. Mr. Ray Ham was appointed as the first lay Principal of Holy Rosary Catholic School. Since 1975 lay leadership and staff have played a key role in the development of Holy Rosary Catholic School. Continuing in the spirit of the Dominican Sisters, the school and community have welcomed those who seek a caring, Catholic school community where educational growth is balanced with pastoral care for all.

As the surrounding area expanded and the population grew so did the Holy Rosary Catholic school site and the student enrolments. Refurbishments and additions have been made so that today the site has changed and grown considerably. Additional building and refurbishments occurred in 1965, 1969 and 1973 when new classrooms and a library were added. In 1986 Holy Rosary opened the first Kindergarten in Catholic Education in Tasmania. New staff facilities were built in 1991 and in 1993 the existing Library was added. The Joan Nichols Wing was built in 1996 and in 1999 four of the original classrooms were refurbished. An additional two classrooms were also refurbished in 2000. In more recent years the school hall was built to accommodate assemblies, whole school Masses, Music and PE.

The development of the Early Years Centre and further refurbishment of Learning areas and the Library, began in 2009 and the redevelopment of the site has continued throughout 2010 and into 2015. Included within this was further development of the Joan Nichols Wing, Grade 1/2 spaces, Canteen and the stage of the Hall for a dedicated Music Space. Additional works also include the completion of a half-court basketball area and the water bank imaginative play space.
