The college enjoys a close relationship with Capella Sublima, an "a cappella" vocal consort based at St. John's College, where its singers rehearse. In the European Renaissance, "a cappella" was a group of musicians attached to a cathedral or the court of a monarch. Capella Sublima specialises in choral masterworks of the European Renaissance. Its extensive repertoire includes Josquin, Lassus, Palestrina, Victoria, Guerrero, Tallis and others. Capella Sublima have been recorded for broadcast by ABC Classic FM and numerous other Sydney radio stations.
