The horses' interest often tell us of visitors before we notice them. They were looking up the hill today at this pair. The grumbles and rumbles and quite amazingly large sounds the koalas were making, a bit like a cross between a revving Harley Davidson, a dog with laryngitis and an annoyed elephant, sort of gave them away anyway.
The sound echoed across the valley. The discussion may have been a property dispute, as one koala was higher in the tree than the other.
Perhaps he was the aggressor, however, as the higher one seemed quite laid back.
He clearly had the penthouse with the view and was not about to give it up.
