A man slammed a kangaroo with his body after it attacked him.
Video footage taken on CCTV video camera shows the animal running after the victim in New South Wales, Australia, as he runs to escape the marsupial.
After chasing him the animal brought him down and the pair fought it out in a fierce brawl which left both looking worse for wear.
A dog bark is heard behind the man behind the man as it tries to protect its owner before the kangaroo turns back and lunches a further attack.
The roo escapes the first punch and the fighters go head to head and exchange punches and uppercuts during the fracas.
He gets closer to the animal in an attempt to escape further blows before grabbing it by the foot and pulling it to the ground.
The victim finally pins down the beast, but takes a few punches before that.
There is no information on whether he was badly hurt during the astonishing brawl.
Roos are not usually spoiling for a fight but there are undocumented attacks which happen in the country when the animals feel threatened.
In September last year The Mirror told how two men who rescued a kangaroo from a freezing river were offered a handshake by the animal as it seemingly offered its thanks.
The rescuers were filmed lifting the kangaroo from the chilly waters of Lake Burley Griffin in Canberra, in a video that’s been widely circulated on social media.
The kangaroo initially seemed nervous when the two men closed in, crouching low and then startling when the first man reached out to touch him.
However, it eventually allows them to lift it up and is carried out of the water.
Holding the animal between them, the two men walked to the edge of the lake, where they then pass the kangaroo up to a third man waiting on the pavement surrounding the water.
In the background of the clip he can be heard saying: "Aw, he's thanking ya."
Responding to people commenting, Julian said temperatures in the ACT were below freezing yesterday.
Replying to one user asking if kangaroos are able to swim, Julian said: “I’d say this one was tired and cold. But hard to climb out as well.
“They can swim though.”
