Shane Rattenbury said he was out running in a suburb of the capital Canberra when he suddenly came up against an eastern grey kangaroo grazing on a front lawn.
“As the kangaroo sought to escape, it landed on me, and its claws dug into my leg.”
Mr Rattenbury tweeted his encounter along with a picture of his bloodied legs, saying: “Mugged by a kangaroo! And this was in the suburbs, had not even got to the nature park!”
The politician said the 1.4 metre (4ft 7ins) tall kangaroo knocked him to the pavement, the claws of its powerful hind legs drawing blood with two scratches to his left leg. His right leg was painfully bruised by the pavement.
Moments later, a passer-by noticed Mr Rattenbury was injured and drove him home.
