For 15-year-old Maddi Cook it's her first shot at a chance at higher grade netball.

Liz Chard, 17, Bridget Beatty, 15 and Annaleese Cameron, 15, are also competing at the games in April.

Julie Fuller, who is also joining them as one the NIAS assistant coaches, said it is a huge opportunity and she is extremely proud.

"It's a huge achievement for them," she said.

"They'd had to trial and every training session is a trial and then we all come together and play games. It's chosen by four of the coaches."

She said it was much harder for country girls because they were further away from big city clubs and their better quality facilities. But they will compete against metropolitan squads. Julie rates their chances.

"This year's (team is) probably a little stronger. I think we might go okay. The girls learn so much, you've got to fight for every ball."

Glen Innes' Mischa Dowling and Bec Cooke will be joining them as managers. That's something of an administrative role, but they're also responsible for the athlete's mental health and diet.

"They're on a learning curve as well, which is good," said Julie Fuller.

"They have to get the girls organised, make sure they're hydrated, that all their dietary requirements are met they've got to have talks to girls all the time.

"Mentally they've got to make sure they're mentally prepared, if there's some home situation that's going to affect them or their game play..."

The final training session is set for March 31 and the actual competition will take place April 12-14.

It will be a very scary experience. The potential to get headhunted is real.

"You have selectors there, you have selectors the whole time."

Julie says "it's wonderful" to get so many Glen Innes girls through to a higher grade.

"We've done this for the last couple of years, we've always punched above our weight.

"We've always tried really hard, because the girls are so passionate about their sport they try really hard it doesn't matter that we've got no facilities.

"They just seem to step up," she said.
