Have to laugh though that the millions spent on security fences around airports and kangaroos and foxes still make it in and 'terrorise' aircraft. Guess they think the average criminal is less intelligent than a roo... Can't even stop large wildlife strikes at airports, and they are not even trying to harm anything. Billions squandered on fences and facade security. Then don't even get started on the billions being spent on edge barriers on roads, where one state proclaimed 1000s saved per year, except the road toll per year was never that high, and has barely changed since the implementation.
