It wasn’t easy going for Buchan who came up against countryman Mick Fanning.
The Gold Coast local pulled off an incredible 9.83 on a monster wave.
But not to be outdone, Buchan hit back with a pair of 8s for a total score of 16.70.
In the earlier heat, Wilkinson wasn’t at his best facing Ethan Ewing, but did enough.
A respectable 7.10 on his first wave saved him in the rough conditions… he moves onto the next round with a final score of 11.57.
