I notice that works are being undertaken to semi-permanently cover many of the water features of this magnificent building. As this building is owned by every Australian and as it attracts great tourist opportunities here, what level of rainfall in the local catchment will be required to return these water features to the beautiful part that they play in the concept of this building?

I thank the member for McMillan. As he would be aware, that question will require some research. I will seek to provide him with an answer as soon as I can.
