St Mary's continues to run a compulsory community service programme, which sees each student complete a minimum of 20 hours of service to the community during Years 10 and 11.
This Community Service programme is aimed at developing values and skills, and an understanding of the importance of supporting local communities. Girls undertake activities in their personal time and also at school.
Activities include assisting at local libraries, helping Riding For The Disabled, Anglicare, the Anglican Board of Mission and Moline House (an Amana Living residential facilty) and the City to Surf Fun Run. There are also two Community Link Days, organised by the school which have had an environmental theme.
