Occurred on February 14, 2015 / Jervis Bay, New South Wales, Australia
Info from Licensor: "A few of us were renting a cabin and it was fairly quiet. We seemed to be the only ones there due to it being off season. The two males were in a confrontation over some females who we met later on and they were much friendlier and we even fed them. After a brief stare down, we witnessed one of the males kick the other into the side of the cabin and the wood actually broke inwards. You can hear the owner of the cabins/land owner behind us telling us that the kangaroo is going to snap it’s neck. The sheer size and force of these brutes is beyond impressive especially up close. Eventually one male chased the other away and that was the end of that."
