With an endoscope on a pole we can check whether this hollow is being used to nest in by Gang Gangs come breeding time in October. Very few nesting hollows are known anywhere. From experience elsewhere we have found that about 10% of hollows that gang gangs check out will be used for nesting. Many tree hollows also hold water and are a major water source for Gang Gangs, which accounts for a lot of their interest in hollows.
User's notes
One of a flock of approximately 12-15 individuals.
This one seen looking into a potential hollow and chewing on bark around the edges.

Chewing bark is also a sign that this may be a nesting hollow. Gang Gangs line the base of their hollows with 2 -10cm of bark chewed to a sawdust. My theory is this may reduce the risk of the eggs and chicks being drowned or waterlogged, should water collect at base of hollow (which happens surprisingly often).
