Budding surf lifesavers have until tonight to sign up for this weekend's two-day carnival in Wollongong.
Organisers of the annual Wave Warriors event, now in its third year, are hopeful of attracting 400 competitors.
Event co-ordinator Michelle Hunnybun urged interested candidates to sign up online.
"We think it is the best carnival on the calendar. Our motto is that 'everyone who attends is a winner, but those who win are champions'," she said.
"It gives a chance for every single child, regardless of their ability, to compete in everything.
"The carnival is open for all kids aged under 10 to under 17 - all they've got to do is go to our website, wavewarriors.com.au, and enter online."
The brainchild of surf lifesaving champion Zane Holmes, the two-day Wave Warriors event tests the skills of competitors from throughout Australia and New Zealand.
One leg was staged for the first time in Queensland, in October this year. And Hunnybun said this could be repeated next year.
"We're now planning on doing four events a year, with the NSW event being our main carnival," she said.
"We're aiming for 400 competitors this year.
"We've listened to responses we've had from surveys and decided to condense the event from three days to two days.
"People found it more convenient to take less time off work. And by taking it to the weekend, more people can attend."
Wave Warriors will be held at Wollongong's North Beach on Saturday and Sunday.
