So the hollows in trees don't always come easy?
I've read it usually takes a hundred years before a gum can develop the kinds of hollows required for breeding by many native birds and animals, which is one reason old trees are important. In this instance a hollow already existed, but the galah was determinedly improving on it. Maybe this is why galahs and parrots need such strong beaks and claws.
