From the video description:
"I had been Paragliding cross country for two hours near Canberra and had reached a position where I had to land. It is the last cleared valley where I could safely land, as over the next ridge there is only wilderness and trees. I decided to land on the concrete slab of the old Orroral Space Tracking Station. I was concentrating on the landing and didn't notice the Kangaroo until after I landed. As it ran towards me I thought it was being friendly so I said 'What's Up, Skip?' It then attacked me twice before hopping away. I packed up my paraglider and had to walk several kilometers to get phone reception and call a friend to come and collect me."
