Walter finished off the competition with a huge 175m dynamic without fins pushing out his own national record by yet another 10m to become one of the world top four.

Kathryn McPhee: world record dynamic without fins & NZ national record in dynamic.
Dave Mullins: equal to world record in dynamics without fins.
Walter Steyn: two Australian national records in dynamic without fins and one in dynamics
Phil Clayton: British national record in dynamic without fins
