The bandy bandy snake looks a lot like the coral snakes we have in Australia too, in Queensland? Red with yellow stripes? I believe they are quite poisonous?

I remember reading about snakes in Australia vs New Guinea. Australia has about a hundred species with the vast majority poisonous and the top few among the most poisonous six of the world. New Guinea had a much higher number of species but the vast majority non-poisonous. Must be some reason for the difference?
