St Mary's Cathedral Choir, Sydney

St Mary's Cathedral Choir in Sydney is the oldest musical institution in Australia. In 1818 a group of choristers was formed to sing Vespers before the Blessed Sacrament in the Dempsey Household, the centre of Roman Catholic worship in Sydney as a penal colony. When St Mary's Cathedral, Sydney, was constructed, the successors of these choristers formed the Permanent Cathedral Choir under the guidance of Catherine Fitzpatrick.

Now over 200 years old, the choir is formed of approximately 40 boy and girl choristers and 12 lay clerks, and sings Mass and Vespers daily (excluding Saturday). The choir has gone on many tours and concerts, sometimes singing with the Australian Brandenburg Orchestra (2003, 2005). They are preparing to go on another tour in 2026. The choir is currently directed by the Director of Music, Mr Daniel Justin, with the help of Simon Niemiński, the current Assistant Director.
