The circumstances surrounding Llewellyn's death have not been revealed, but his brother Jaret said he had endured difficult times after suffering a head injury.

"Kreg was my hero and an inspiration to so many around the world," Jaret Llewellyn wrote on Facebook.

"Anyone who had the privilege to know Kreg could see he had a huge heart, because he wore it on his sleeve.

"Kreg will always be the most talented athlete I have ever seen, not only on the water but in any sport, you asked him to try. 

"During the height of the professional tour, Kreg was the most dominant male multi-event skier. 

"He could do anything he set his mind to."
