(Reuters) -Australia's Jack Robinson earned his first victory of the season on the world championship tour while compatriot Isabella Nichols won the women's title at the prestigious Rip Curl Pro at Bells Beach, south of Melbourne, on Sunday.

Paris Olympics silver medallist Robinson scored 7.77 on his third wave after a 6.37 earlier to finish with a two-wave total of 14.14, edging out Japan's Kanoa Igarashi, who managed 13.87 and missed out on a second tour victory of his career.
