A pianist since the early age of 5, and an organist from 12, Callum Knox is one of the finest young organists of Sydney. He won a scholarship to the Sydney Conservatorium’s Rising Stars programme in 2019, and studies under Philip Swanton under a full scholarship for tertiary study at the Sydney Conservatorium. Callum began as Assistant Director of Music at St Mary’s in 2023, having previously worked at St James’ King Street, and been the Junior Organ Scholar at St Andrew’s Cathedral.
Callum graduated from St Andrew’s Cathedral School in 2019, where he earned full marks for his performances in organ for HSC Music Extension, as well as a nomination for Encore, the HSC’s concert showcasing the top performers in NSW. He also achieved first prize in the intermediate section of the 2020 Sydney Organ Competition, and completed his Licentiate in organ with High Distinction.
Callum has also performed highly regarded organs around Australia and beyond, such as in the Sydney Town Hall on multiple occasions, as well as St Paul’s Cathedral Melbourne, St Paul’s Cathedral London, St George’s Chapel Windsor Castle, and St Eustache in Paris. Callum is also a trained vocalist, as well as an avid long-distance runner and surfer, and hopes that the organ will continue to be vital for worship and entertainment long into the future.
