A northern Victorian man is in shock after a rampaging kangaroo caused thousands of dollars in damage to his home in the northern Victoria town of Echuca.

The kangaroo was part of a mob that made its way into a housing estate in Echuca on Tuesday afternoon.

The large eastern grey kangaroo and three others got into the front yard of one home and ended up in a swimming pool.

Then it crashed through the front window of Paul Giogianni's house, causing extensive damage.

"It's lucky that (the damage) is contained to the lounge room and the little bit in my bedroom," he said.

"It could have gone on a rampage and destroyed the whole house."

The kangaroo was badly injured after crashing through the window and left a trail of blood throughout the house. It was later put down.

Mr Giorgianni says he cannot do anything to replace damaged carpet, curtains and windows until an insurance assessor arrives.

He says no-one knows why the large kangaroo ended up in the area.

"It's just unheard of with that much feed around to come into town like that," he said.

Mr Giorgianni, a truck driver, was away from home when his boss rang him to tell him what happened.

He says he did not believe him when he was told his house had been broken into by a kangaroo.
