Just to add an observation I made today in relation the the recent discussion around this.
In one of the tall pines in the Fadden Pines car park, numerous Sulphur-crested Cockatoos were working on stripping bark from a pine.
What I found particularly interesting was that they aren't doing random patches, but had rather left a remarkably straight vertical line (several cm width) of bare trunk extending from just above the ground to about 11m in height. When we left, a cockatoo was still working on extending the top of the line.
There was no apparent sign of grubs on the bare patches of trunk, or any apparent reason why they might strip a narrow vertical line.
