Fresh from signing a two-year deal with the Jets, Devlin was one of four train-on players alongside former Jet Ramy Najjarine, keeper Jordan Holmes and Lachlan Wales named outside the 18-man squad.

They will work with the team in the lead up to Tokyo - the Olyroos first appearance at the games since Beijing 2008.

Connor O'Toole and Najjarine were part of the squad which helped earn the Olyroos qualify by finishing third at the Asian Championships. Angus Thurgate, Jordan O'Doherty and Jonny Koutroumbis have also been involved in camps or games but missed the final cut.

After two breakout seasons with Wellington, Devlin said he was excited to make the move to Newcastle and play under new coach Arthur Papas.

"I've watched some of the team's Arthur has coached over the years and he plays an attractive style," Devlin said. "To play attacking, brave football supporters want to watch is exciting.

"The move to Newcastle is a new challenge for me but one I'm eager for and as a one-team town. I look forward to bringing the fans back. That's a strong goal of mine."

Devlin will help fill the hole left by Steve Ugarkovic, who departed late last season to reunite with former coach Carl Robinson at Western Sydney.

"Cameron has established himself over the last two seasons as one of the A-League's premier midfielders, so having him commit to the Newcastle Jets is a clear statement about the direction we are heading," Papas said.

"Cameron fits the profile both on and off the field that we were looking to attract and I've got no doubt we have secured a player with the capabilities to play at the highest levels."

Meanwhile, coach Graham Arnold has revealed he received dozens of knock backs from overseas clubs as he tried to get players made available for Australia's Olympic football campaign.

Striker Mitchell Duke and defender Ruon Tongyik are the two players over 23 that Arnold named, with stars such as Mathew Leckie, Jackson Irvine, Tom Rogic, Aaron Mooy and Mat Ryan absent.

Arnold said FIFA regulations allowing clubs to make players unavailable for selection had worked against him.

"This is probably one of the most complicated processes I've ever been through to select the squad," Arnold said. "I probably made 30 to 40 phone calls to clubs for over-age players to see which players could get released. Pretty much out of 30-40, came back three (positive)."
