THERE'S more than a touch of Rocky Balboa about humble Aussie Alex Leapai and his unshakeable dream of becoming heavyweight boxing champion of the world.

Drugs, alcohol, violence and prison are all part of Leapai's life story.

It's the kind of story Hollywood movies are made of.

Should the 34-year-old father of six spring one of the biggest upsets in boxing history by beating Wladimir Klitschko for the unified world heavyweight title in Oberhausen, Germany on April 26, there's every chance Hollywood directors will come knocking.

Leapai took his wife, six children and his mother, whom he brought back to Australia following a recent visit back home to his birthplace of Samoa, to Dreamworld theme park on the Gold Coast on Wednesday for a family day out before locking himself away in an intense two month training camp.

As tough as he is, Leapai admits he was shamed by his young children into riding the park's famed Tower of Terror - the tallest free-falling ride in the world.

"It was scary, I mean really scary. I'd rather all you guys (media) punch me in the face than get on it," he said before his one and only ride on the park's most popular attraction.

"I built the courage because my son got on and I didn't want to look scared and then my mum jumped on so I had to ride it."
