Unfortunately, however, only two of the group dubbed the Fearless Five took part in the successful attempt on May 31 over Peris Valley, California.

Cloudy conditions in the four days prior had complicated preparations.

Success didn't come until the final jump on the last day.

Melissa Harvie and Steve Cusato made the cut and were successful as part of 119 people in the Australian Freefall Formation Skydiving Record.

The experienced Tony Maurer was unlucky to miss out, having been cut following the third last jump.

Deepening the blow was he and Ms Harvie helped set the previous record of 112 skydivers at the same location in 2010.

Veteran skydiver Ian Robertson from Port Macquarie and Comboyne's Janelle Hinze also missed out.

Australians comprised three quarters of those jumping, with people from 11 other countries rounding out the total number.

Seven planes took them to an altitude of 19,000 feet before they leapt into the blue.

At points during their descent they reached speeds of nearly 200 kilometres per hour.

Mr Cusato said it wasn't as bad as he thought it would be.

"The scariest part is when you first exit the plane," he said.

"Surprisingly there's quite a bit of room up there."

The Wauchope man did 38 practice jumps in California in the lead-up to successful attempt.

"The pressure was like nothing I've ever experienced," he said.

"You can't stuff it up for anyone else."

The team were not necessarily as experienced as her previous attempt, Ms Harvie said.

While they were quite well prepared, four days of bad weather in the lead up to the weekend of attempts impacted training.

"Sadly we lost a lot of people [who weren't able to jump] because they didn't have the opportunities to consolidate their flying," Ms Harvie said.

Training in difficult conditions would form a greater part of future preparations, she said.

Their success was noted by the king of the modern adventure rush, Bear Grylls.

The survivalist gushed praise for the Australian daredevils on his Bear Grylls Adventure Youtube channel.

There is already talk of a 2019 attempt, Ms Harvie said.

And will she be attending?

"I would reckon so - I've still got a few good years in me."
