The contract for the construction of the organ was awarded in 1969, during the construction of the Opera House, and the organ was completed in 1979, six years after the opening of the building. Since then the electronics have been updated, including a major refit in 2002, but the musical specification is unchanged from that developed by Sharp starting in 1967.
In April 1994 the Sydney Opera House Trust awarded the contract for ongoing maintenance of the organ to Mark Fisher, one of the original staff of Ronald Sharp.
In addition to its mechanical action, the organ can be played remotely by an electronic system, enabling it to be played from a remote console, or a performance or passage can be recorded by a system built into the keyboards and played back by the electronic action. This system is used by visiting organists to select the registration (the combination of stops) that they will use, enabling them to stand in different parts of the hall and hear the results. Its stops are entirely electronically operated and programmed.
