ALEX Leapai's bid to end Wladimir Klitschko's reign and become Australia's first heavyweight boxing champion will happen in Germany in April.

Klitschko has been given a date of April 26 for the latest mandatory defence of his WBO title, and the Ukrainian star will put all of his titles on the line against the 34-year-old Aussie.

Leapai has won 30 and drawn three of his 37 professional fights and will take on a man who hasn't been defeated in 10 years.

Leapai earned his shot at the champion, who holds the IBF and WBA belts, by beating Denis Boytsov in a 10-round epic in Germany in November.
