A company spokeswoman said no private property or infrastructure was affected by the  subsidence, which occurred in dense bushland on the eastern side of Harry Graham Drive.

‘‘Residents in the area were notified at the time of the event and also of the rehabilitation works, which are now complete, with re-planting of the area to occur in coming weeks,’’ the spokeswoman said.

‘‘The works included the clearing of ground-level scrub and some coral trees, levelling of the surface, and the erection of fencing to secure the area during the works.”
