The land of beaches and barbecues is fast becoming a production line for athletes on snow and ice after two more Australians captured snowboard world championships in Spain.

Hard on the heels of Alex Pullin's surprise win in the snowboard cross event at La Molina, Holly Crawford and Nate Johnstone have taken out the women's and men's halfpipe event in an incredible three days of competition for the Australians.

Both boarders effectively captured the title in their first run down the pipe, Crawford's score of 26.7 holding up in the second round to beat Switzerland's Ursina Haller (23.4) and China's Jiayu Liu (22.5).

Johnstone's score of 26.8 was enough to edge out Switzerland's Louri Podladtchiko (26.2) and Finland's Markus Malin (24.2).

Crawford, a silver medallist at the 2009 world championships in South Korea, was always expected to be a contender in Spain, having won three career World Cup events.

Johnstone, though, was more out of the box.

The 20-year-old has stood on the podium but is yet to win a World Cup event and had also finished runner-up at the world junior championships just five months ago.

"It means a lot. I've been training real hard this season to do well - and I did," said Johnstone, who missed the 2010 Vancouver Winter Olympics through injury.

"(With three Australian gold medals) it couldn't have worked out any better."

While the standard of halfpipe competition at the world championships is not a true reflection of the sport, with most of the best riders skipping the event in favour of staying on the pro tour, Australia can nonetheless now lay claim to having some of the best snowboarders in the world.

Torah Bright is undisputed as the best women's rider after her gold medal at the 2010 Winter Olympics while Crawford, who finished eighth at the Vancouver Games, has also won a number of top-class international competitions.

Pullin, Crawford and Johnstone join Kirstie Marshall, Jacqui Cooper, Alisa Camplin (aerials), Dale Begg-Smith (moguls) and Zali Steggall (slalom) as Australia's winter sport world champions.
