Box jellyfish (Chironex fleckeri), the infamous lethally venomous of northern Australia's coastal waters, is the most lethal jellyfish in the world, and one of the most dangerous animals in the world.(Picture also from Wikipedia).
Wildlife of Australia seems to come in 2 varieties weirdly cute or very dangerous -- multiple species of poisonous snakes, saltwater crocodiles, cassowaries (people size birds with a 5 inch long dagger-like claw talon that they can use for defense), several species of poisonous spider and one animal belonging in both the cute and dangerous catagories -- the duckbilled platypus. Male platypus have venomous ankle spurs.
