Information from 1989 OHTA Conference handbook, CD program notes "Great Australiasian Organs II" (Priory PRCD 516) and Simon Pierce's website:

This instrument was built by Johannes Klais of Bonn, Germany in 1986 (opened in May 1987) for the Concert Hall designed by Brisbane architect, Robin Gibson. Robert Boughen O.B.E. was the consultant for the organ. This is a splendid example of a large modern eclectic concert hall organ with a large variety of stops whilst still having its own distinct Klais flavour. A second Principal 8' was added by Klais to the Great in 1988.

Hans Gerd Klais and Robert Boughen drew up the specification and the organ was designed by Klaus Fluegel. Theo Eimermacher voiced the organ. Guether Schumacher was the installation foreman. Of interest is the fact that this was the first organ that Philipp Klais worked on and helped him decide which career path to take. He is now in charge of the firm.
