Giant aggressive kangaroos have been attacking people in the coastal town of Maaroom on Queensland's Fraser Coast. A number of people, older ones have been injured. It is odd, as I have noticed from my long time in the bush, encountering thousands of roos, that these are usually peaceful creatures, and only once did I have a King Kong size roo confront me, but wisely he soon backed down. Yes, people have died because of kangaroos, but this is usually from road accidents.
People in that little town are starting to carry big sticks but unless one is skilled in stick fighting, a determined roo will still wipe you out. And, it is likely that the roo will be injured if struck violently in the head, or not injured at all by a body strike, only made angrier. Since this is Australia, not America, the problem cannot be solved by the individual, beyond avoiding these fellows. People probably encouraged this behaviour by feeding them, which broke down the human/roo barrier. Treat roos as would other dangerous animals, ones which like bears in North America are a protected species, and illegal to kill, let alone harm. Even whacking one with a stick is legally problematic, and avoidance is the best option, as with any dangerous creatures, including bears and humans. However, I do not agree with the advice of rolling up into a ball, as a roo jumping on one’s back could break the spine.
