Canteen facilities are available everyday at lunchtime. The canteen is staffed by a Canteen Manager and parent volunteers. The canteen exists as a service to the students. The school has made great strides towards meeting the requirements of the NSW Healthy School Canteen Strategy and have made the offering of healthy options a priority at St Mary's. Canteen Helpers are usually rostered once per term and new helpers are always welcome.
Parents wishing to order lunch for their children are asked to write the child's name, class and order clearly on a bag or lunch box and place the required money inside. These are collected each morning before school at the canteen. The canteen menu and price list is distributed at the beginning of the school year and can also be found below.
