Trees which are no doubt full of poisonous spiders.
Nature in Australia is bizarrely dangerous in ways that it isn't anywhere else in the world. The country has a hugely disproportionately number of poisonous snakes and spiders, and the kangaroos will happily kick the living shit out of you if provoked. But the following video shows that even the trees can be dangerous in ways that are fairly unbelievable. It was clearly a very windy day, and there are a lot of smaller branches on the road already.
But the domino-like way in which the trees fall, narrowly missing a couple of cars, is amazing.
