10. Sharks
Source: Iconosquare
The three most dreaded shark species in the world are the Bull Shark, the Tiger Shark, the Great White. Australia has them all.
Bull Sharks are the most aggressive sharks in the world, and, therefore, the most dangerous. More people are killed by Bull Sharks than any other species of shark. Not only are they aggressive, but they are persistent- rarely leaving a victim after just one bite.
