With pinpoint precision and a sporting competitiveness, 50 skydivers will leap into the air for a stunning display at a record attempt.
About 15,000 feet above Jurien Bay, skydivers ranging in experience from thousands of jumps to only a few will link their arms and legs together on May 31 and June 1 to try to beat the State record for the biggest formation.
Skydive Jurien Bay manager Chris Sparrow said the divers had been practising for weeks to perfect their "helix" formations, which had been especially created by skydiving experts from the Eastern States.
Ms Sparrow said for the formation to work, divers from three aircraft had to link on to a teammate.
To beat the State record, the formation must include more than 42 divers.
"We're definitely feeling confident and we've really seen people's skills improve," Ms Sparrow said.
