A swimmer paws at the water as he ascends from behind a breaking wave at Bronte Beach, Sydney. Underwater photographer Mark Tipple's latest work gives viewers a spectacular turtle's eye view of swimmers as they roll in the wake of 15 feet high waves.

Brave Mark, 29, has won acclaim for his unique pictures and travels around Australia diving under powerful waves. Using his underwater camera he captures the "battle" between man and the awesome power of the ocean.

His series, which he is compiling into a forthcoming book, shows swimmers frozen in time as they dive below the surf to avoid being pounded. These never-before-seen pictures from the recently finished Australian summer show his series, 'The Underwater Project'.[Photo/CFP]
