Music
St Peter's has a strong tradition of fine church music, with experienced organists employed for both morning and evening services and weekly vocal or instrumental soloists for services. The church's own choir leads hymn-singing, presents anthems and combines with other musicians for concerts and services. The choir practises regularly and welcomes new members.

Cantorion, a Welsh male voice choir, but with members from many countries from Russia to Sri Lanka, practises at St Peter's weekly. They present an annual St David's Day concert, and a Welsh hymn-singing festival as well as music in many European languages.

The church has an extremely good acoustic, as well as its splendid organ and fine grand piano, all of which features make it popular for concerts. Various societies, such as the Sydney Schubert Society, make St Peter's their preferred venue.

St Peter's welcomed Jessica Lim as morning church organist from the beginning of 2009. Currently a Year 12 student at PLC Sydney, Jessica has her AMusA on piano and AMEB Grade 7 on violin. Since she was 9 years old she has been learning the pipe organ which she now studies at the Sydney Conservatorium with Philip Swanton. Jessica has played for many school functions on the grand organs of both Sydney Town Hall and the Opera House, has performed at Young Organists' Day at the Town Hall for the last two years and has been placed in the Sydney Organ Competition in the last three years. In 2007 she was selected by 2MBS-FM to give a recital as part of their Young Performers series. In 2008 Jessica was chosen as one of three young organists to play at the Rising Stars concert in Canberra for the World Day of the Pipe Organ. Jessica comes to St Peter's with this background of success in organ-playing and with the experience of strong involvement in the musical life of both her school, and her parish Croydon church. The organ, installed in 1885, was made by Messrs Maley, Young and Oldknow of London and is the only known example of their work in Australia. Well-known Sydney organ builder and organist, Peter Jewkes, has described the St Peter's organ as of "considerable musical and historical value on a world scale."
