The Tanunda Unit is a purpose-built facility for students with severe and multiple physical disabilities and / or intellectual disabilities.

The Tanunda Unit is an integral part of the Tanunda Primary School community. Students who are able, are part of an inclusion program in mainstream classes in the afternoons. Students from mainstream classes are invited into the Unit 'Safe Play' area during Recess and Lunch. Several students from the mainstream classes have earned their "Wheelie Licences" allowing them to support students who are in wheelchairs.

In addition to this integration into the primary school community, students participate in community-based activities including swimming at the Tanunda Recreation Centre and bowling at the Barossa Bowl.

The Unit was built as a result of the dedicated efforts of parents of students with disabilities. For many years there was no appropriate learning facilities for children in the Barossa. To be eligible for consideration to be placed at the Tanunda Unit, the student must live in the local region district and meet a range of criteria including Guidance Officer recommendation for Special Placement.

The Unit has a Coordinator, teachers and SSO support staff the number of which varies according to student enrolment and specific needs.
