IT was sibling rivalry at its best at Duranbah Beach yesterday as 11-year-old surfer Tyler Wright trumped her older sister Kirby in the dying seconds to win the 14 and under girls division of the Billabong Occy's Grom Comp.

While severe flooding and wild conditions forced a weeklong postponement of the event last Thursday, the huge storm generated waves created a perfect bank off the Duranbah break wall, resulting in epic 1-

1.5m (3-4ft) waves for yesterday's final day of competition

Progressively moving from fourth to third and then second as the 25-minute final progressed, Tyler struggled to challenge her 14-year-old sister who comfortably held down first place with 8.50 and 7.25 rides.

Moments before the siren blared, Tyler took a wide outside wave, riding it all the way through to the shore, finishing with a radical close-out re-entry to put the decision in the lap of the judges.

Requiring an 8.01 to steal the win from her sister, Tyler threw her hands in the air as the 8.80 score was read out, pipping her older sibling by less than a point.

Main Beach surfer Chris Bennetts, son of former Iron Man Mark Bennetts, used impeccable timing and wave selection to upstage his more fancied opponents and secure his best result in competition to date, winning the 16 and under boys division yesterday as the tide receded into the afternoon and the wall bank at Dbah turned it on.
