Did This Guy Seriously Punch A Wild Kangaroo Buck In The Face?

You see, here's the thing - NEVER mess with a man's dog. Ever. I don't care if you're a human being, a shark, or a kangaroo. Don't do it. This Australian tough guy takes on a kangaroo that's trying to claw and strangle his dog in the wild. So what does he do? Well, he does what any normal human being would do. He punches that wild kangaroo in it's face.

That sounded way more normal in my head.

Is this normal in Australia?
