THE WEST ORGAN
The West Organ was installed in 1993, and dedicated on Advent Sunday. It is placed on a specially constructed gallery at the West End of the Cathedral. Organ and Gallery together form a striking feature complimenting the graceful architecture of the Nave and Chancel.

The Organ is the largest mechanical-action instrument to be installed in Western Australia since the similarly sized Ronald Sharp Concert Hall Organ of 1974. The casework is made of Tasmanian Oak, and the front pipes are of burnished tin. The organ has 4 divisions, 46 speaking stops and 3446 pipes.

THE CHANCEL ORGAN

In 1994 a new Chancel Organ was installed in the chamber under the Bell Tower. Consisting of 17 stops in 3 divisions, with mechanical key and electric stop action, this small organ is designed to accompany choirs singing in the Chancel. Electric over-ride enables both the Chancel and the West Organs to be played simultaneously from a third, free-standing console.

THE CHAMBER ORGAN

This instrument was built in 1987, and can be placed anywhere in the Cathedral to serve as a continuo instrument. Its five ranks of pipes are enclosed in a swell box and played from a single manual. By shifting the keyboard, the pitch can be raised or lowered a semi-tone.
