A 26-year-old man risked his life by jumping into the water and climbing on the whale while two sharks were gorging themselves on its flesh.
"Out on the boat with the boys and one of my mates thought it'd be pretty funny if I surfed the whale, so I just did it," Harrison said.
Harrison says it wasn't until he was on top of the whale that he realized how dangerous what he'd just done was, and he says looking back, it's something he would never do again.
Authorities say because the whale was dead and Harrison didn't remove any part of it, he won't be fined.
