Cornerstone College has bookable meeting and workshop rooms within a larger campus of sports, performing-arts and educational facilities in Mount Barker.

The college’s official hire page confirms venue availability after school, on weekends and during school holidays. Facilities extend beyond meeting rooms to theatre, dance studio, large event spaces, sporting fields and outdoor areas, all separately arranged with the school. The general listing does not identify an exact meeting-room configuration or capacity, so one should not be invented for this broad multi-room entry. Contact the college’s facilities team for the intended room, access and equipment.
