A jogger out for a pre-dawn run has been injured after a car slammed into a kangaroo, flipping the animal into him.

Sam Walter, 28, said the bizarre collision might have been karma for his choice of dinner on Tuesday night - kangaroo steak.

He sustained leg injuries when the kangaroo was propelled towards him "like a football" by the impact.

"It was actually airborne and it took me out," he said.
