A tail feather from the Lyre bird, a bird unique to Australia was the inspiration for the sculpture. Conceived to celebrate this iconic bird, the sculpture also alludes to flight and travel.
The stainless steel feather inclines toward the terminal foyer, reflecting sunlight and sky and is itself reflected in the glass facades. At night the illuminated red glass wall within the foyer transforms the feather into a regal plume.
Over ten metres in height, the complex structure supporting the paired barbs of the feather appear to filibrate, creating an ambiguous illusion of reflection and reality.
Like the Lyre bird mimicking sound, "Willinga Plume" is mimicked and reflected in the surrounding facades of the building.
