Canberra's kangaroos first made international headlines when an attack on a former cricketer outside Parliament House was captured on film.
Now, a 44-year-old public servant has come forward to tell of how he was thrown off his bike by a pack of five eastern grey kangaroos in Tuggeranong last month, leaving him with a "traumatised" kidney and shocking bruising.
Neil Buttriss said he was along the Point Hut to Pine Island trail on his usual commute to work at the Department of Human Services from his home in Gordon on December 8.
"I ride from my house to work on the river trail every day and you always see kangaroos, rabbits, wombats and you're blasé because they just scatter," Mr Buttriss said.
He said he was speeding along the track at about 15km/h when he saw the five kangaroos scatter as he approached.
"That morning I was going down quite steep rocky trail and there were five kangaroos to my left and I noticed them and they went to bounce away but, at the last second, one turned and slammed into my front wheel," he said.
Mr Buttriss said the kangaroo was a large male, nearly as tall as him.
"The kangaroo got up and hopped away."
But, for Mr Buttriss, the crash proved disastrous and he was badly hurt. "I went supermanning through the air and landed on rocks off the side of the trail," he said.
Still in shock, Mr Buttriss got up, brushed himself off and walked home.
"I'm a mountain biker so I'm used to coming off, so I walked home. I had scratches and cuts and all sorts, and my lycra was all torn up.
"Then I had a bit of a shower and called my boss and said I've had a bit of a stack," he said, thinking he would be fine for work the next day.
But his "she'll be right" approach was short-lived. "The next morning when I woke up I was all bruised and swollen so I thought I should go to the doctor.
"I had ultrasounds, I had x-rays and it ended up that I had bruising into my kidney - It was apparently releasing proteins it shouldn't have, so it was basically traumatised - and some slight tears of tendons," he said.
Mr Buttriss was so nervous about getting back on his bike and taking on the track that he recruited a friend for his return ride.
"On the first Monday I rode with my mate and I said you go first to scare away all the wildlife. When I went past the place where I crashed, I was very nervous going past again," Mr Buttriss said.
"I rode down there almost walking pace."
Mr Buttriss said the accident had taught him to never again underestimate the force of nature.
"It is almost a month ago and I still have signs of bruising. You see wildlife and you get blasé about it, you think they'll scatter."
