Sydney Philharmonia Choirs is Australia's most established and finest choral organisation and will be celebrating its centenary in 2020. Members of the Sydney Philharmonia Choirs believe in sharing the choy of choral singing with fellow choristers and audiences alike. Members of the Choirs, which across the organisation number 1500 people, voluntarily give their time and talents to sing in extraordinary performances with major international artists and orchestras, in the country's leading concert halls. The choirs appear regularly with the Sydney Symphony Orchestra in addition to presenting its own series of programs each year. Brett Weymark has been the music Director of Sydney Philharmonia Choirs since 2003.
