Apparently Australian Kangaroos can be quite aggressive, if not deadly.

Australians living in the nation's drought-ravaged capital have been warned to keep their distance from aggressive kangaroos after the iconic marsupials attacked one woman and killed a pet dog. [...]

A senior wildlife ecologist with Environment ACT, Murray Evans, said on Wednesday the kangaroos could pose a threat to people and dogs, with one woman savaged by a large kangaroo as she was walking her small, pet dog in a paddock last week.

"Her dog went near the kangaroo and she followed and before she knew it the kangaroo lashed out, scratching her down the side of her body," Evans told Reuters.

Another woman told how a kangaroo drowned one of the four dogs she was walking with a friend, attacking it in a pond and holding it under the water with its hind legs while it hit out at one of the other dogs with its front legs.

Aussies should probably take warning and carry a gun for protection. Oh wait, guns are illegal. Well, perhaps a big knife then. Oh wait, that won't work either. Perhaps just something sharp and pointy. Oh wait, nails are practically banned too.
