There are three schools in Australia who belong to the international family of Sion Schools: Marist-Sion College and Catholic College Sale, who both recognise the Sisters of Our Lady of Sion as a founding charism, and Our Lady of Sion College, Box Hill.
The Principals and staff of the three Colleges meet regularly to reflect on their shared tradition, to inform staff about the history, charism and work of the Sisters of Sion, and to build community.
