They might be the only surfers in the world who want to see more people in the water.

About 90 surfers from 17 different countries gathered at Byron Bay, on the NSW far north coast, this week for the first Association of Adaptive Surfing Professionals (AASP) contest ever held in Australia.

Contest organiser Mark "Mono" Stewart knows a deeper pool of competitors will make it more difficult for him to add to an already bulging trophy cabinet, which includes five adaptive world surfing championships.

But that is a risk he is happy to take.

"My main thing is to be able to help people get back into the water," he said.

"I'm sort of an old bloke now, but I want to see the future of our sport go global, and it is.

"I'm proud to be part of that as one of the pioneers."

Paralympic push

The AASP already has a four-stage world tour, but there is a concerted campaign to get the sport into the 2028 Paralympics at Los Angeles.

Tour surfer Alana Nichols, who is a board member of the International Surfing Association (ISA) Athlete Commission, said it was all about numbers.

"We've done everything we can and the sport has grown exponentially since we started," she said.

"We're just hoping for more women to come out and surf. 

Sixteen-year-old Annie Goldsmith, who has cerebral palsy, was quick to sing the praises of the adaptive surfing community.

"There's a girl in South Australia who got me into it, and I haven't looked back since," she said.

"Just have a go, come out to one of the events and watch if you don't know if you want to do it or not yet.

'A matter of millimetres'

Adaptive surfing does its best to accommodate athletes with different abilities across nine categories.

Maureen Johnson, who is the AASP's head of classification, said several factors were considered.

"So we test strength, we test flexibility, we'll measure [limbs] with a tape measure," Dr Johnson said. 

"It is literally sometimes a matter of millimetres and degrees. 

Vision-impaired surfer Aaron Paulk used plenty of both to score a perfect 10-point ride on finals day at the Byron Bay event.

The Hawaiian relied on his limited peripheral vision, and a local surfer acting as his spotter, to surf his way across the peeling waves on offer at The Pass.

"So he gets me into the waves and then it just goes into the flow state after that," he said.

"If you feel something drop out then you go up and hit it.

"Just from repetition, just knowing that motion and seeing the variation between white and green or blue, depending on what ocean you're in, I can pick that up through my periphery."

The surfers can use a range of equipment, depending on their category, but the competitive edge won't necessarily come from the board they are riding.

UK competitor Pegleg Bennett uses a prothetic lower limb and has spent years finding the best design. 

"When I stand the joint gives, so my foot actually sits flat on the board," he said.

"Before this I spent a lot of time up on my heel or the edge of the foot. 

"You don't get a lot of purchase, so it's a bit … wobbly."

The Byron Bay event featured a fairytale finish.

After working for years to make the contest a reality, Mark "Mono" Stewart scored an almost-perfect 9.5 ride in the last minute of the final to win his division.

It goes without saying, although every surfer says it, he was "stoked".
