A 35-year-old Australian man, wearing only his underpants, survived a nine-storey fall Tuesday when he lost his footing and accidentally fell from a building, police said.

The police said the man was attempting to do planks across his neighbor's apartment when he lost his balance and fell 30 meters off the ground.

Police spokesperson Ros Weatherall said, "He was skylarking around, building planks across to his neighbor's place when it happened. He was very lucky."

According to residents around the flat in Perth, western Australia, they heard a loud and strange noise coming from the apartment before midnight.

One concerned neighbor dialed the police number for assistance.

"He was conscious, he was going 'Well, well, where am I? What happened?' and that was about it," the resident said.

"It was a horrendous fall because he actually came down nine storeys."
