Australians Jack Robinson, Liam O'Brien and Ryan Callinan are quarter-finalists at Sunset Beach, but leading Aussie surfer Ethan Ewing has crashed out of the Hawaii contest.
Ranked world No.2 heading into the season, Ewing took down 11-time world champion Kelly Slater early on Sunday, with the surfers battling wild three-metre waves and windy conditions on Oahu's North Shore.
