Australian Owen Wright is through to round three of the Margaret River Pro but his brother Mikey wasn't as lucky.
Owen Wright, donning a helmet in the big conditions on Monday, posted a two-wave total of 15.00 in his round-one heat to easily beat Frenchman Jeremy Flores (11.77) and Brazilian Deivid Silva (10.00).
It means Wright and Flores progressed safely through to round three, while Silva was pitted into the elimination second round.
"I've had a few beatings, so I probably know the worst of it," Owen said of tackling the big conditions.
"I had a helmet on out there. The last thing I want to do is go for that end turn and come up on the rocks. It gives me that confidence to go for it.
"The conditions are super tricky. We were sitting a long way out at the start, because there were some massive waves coming through, but you just can't get into them with that wind.
"So for my first one I sat like 30 metres further in than the other guys and I only just got it."
Mikey Wright was relegated to the elimination second round after losing his opening heat, and he failed to come up with the goods against countryman Jack Robinson and Brazilian Yago Dora.
Wright's two-wave total of 12.06 fell just short of Dora's 13.00 and also adrift of Robinson's 14.17.
Round two proved brutal for the local hopes with all four eliminations being Australians - Cyrus Cox, Reef Heazlewood, Jack Freestone, and Mikey Wright.
