In 1932 an organ by John Whitely was placed opposite in the north transept. In the 1950s the instruments were amalgamated to be played from a single console, thus constituting the largest church organ in Australia. There was a further rationalisation of the organs in 1998 with a restoration by the Canadian firm of Orgues Létourneau. The Whitely was removed from the north transept gallery. The organ, as reconstituted by Letourneau, consists of four manuals with mechanical action, comprising the rebuilt Hill organ, together with the best of the Whitely pipework.
