One of them is Nyngan's very own Terrance Ryan who has proven he's got what it takes to play rugby sevens for Australia.

"I was shocked because out of the amount of players that trialed I didn't expect to get picked," the 18-year-old said.

"It's my first time I've ever been picked for a representative side so it's very exciting."

This Friday Ryan will join 46 female and 86 male players in a special four-day camp in Sydney where their skills will be put to the test in front of a panel of coaches and experts.

Following the camp two First Nations Sevens squads of 20 will be chosen to compete around the country, with the ultimate goal of the program to find players to represent Australia at the 2024 Olympics.

Former Australian sevens assistant coach Jarred Hodges has led the project and said it has been a "humbling" experience.

"This is the first time in the game's experience that such a project has occurred and to have had the opportunity to lead that, it is pretty humbling," he said.

"But daunting as well, we've seen across all the communities the depth of talent and also the keen interest in playing rugby, so we just want to make sure we can write a program for all, not just our top players but also building and growing rugby through our grassroots."

Hodges said the camp will replicate the demands of men and women who play for the world series, where they will play back-to-back games across a two day tournament to demonstrate their skills and decision making abilities under fatigue and competition pressure.

"It's going to come down to how they perform under pressure, against the quality of opponents that we've bought down together, and they're going to need to do that over the course of the two days," he said.

Other rugby sevens hopefuls selected in the region include Ryan's sister Alahna Ryan, Brooke Williams, and Lilly-Ann Mason, who all trialed in Dubbo, Lakeisha Orcher and Clynton Edwards from Bourke and Benjamin Griffiths from Cobar.

Yet Hodges commended Ryan for his speed, which is needed to play rugby sevens and said the aim of the program is to increase participation rates especially of Aboriginal and Torres Strait Islander people.

"[Ryan's] got some talent that boy," he said.

"That's that daunting part because a lot of people have scarified a lot to come down, and I know talking to all the participants they've put everything on the line and they're excited about the opportunity."

"And that's part of it, it's to increase the access and opportunity for our first nations people because a lot of them haven't had that previously."

The final two First Nations Sevens squads are expected to be announced on September 12.
