St. Saviour's organ fills the south choir aisle of the Cathedral, with over 3,000 pipes and over 43 stops (different sounding ranks of pipes). It was built in 1883 by the eminent firm of Forster and Andrews of Hull, Yorkshire, and is the largest of their organs still intact. It was installed in 1884.
The wrought iron organ case erupts at the top into florid finials and the pipes have gilded patterns on a ground of buff and grey.
The organ was fully restored in 1979, with every care being taken to preserve its character.
Edmund Thomas Blacket was an organist as well as an architect. It was he who prepared the specification for the organ builders.The gilded patterns on the front pipes and the iron filigree frame of the case are his design.
The two final ranks of the organ, including a 16' reed unit and a separate Vox Humana (Latin for human voice), arrived in February 2006 to complete the organ after 121 years. These additions make it one of the most versatile organs in Australia.
