The 22-year-old wanted to be a professional surfer before he took up acting and regularly hit the waves to achieve his dream.
However, one trip to the beach almost ended in disaster after Hemsworth got caught on a rope, reported Men's Health.
"I surfed competitively from age 13 to 18. Every day, before and after school. I wanted to surf for the rest of my life. I even had it as a subject in school for a number of years. They teach you all parts of the surfing industry: How to judge surf heats, that sort of thing.
"When I was a kid, one time I got my leg rope wrapped around my whole body like a ball, under water. Couldn't get up. I was in waist-deep water, but I almost drowned. You know, I've had a few times," he said.
