Socceroos coach Graham Arnold has named a 23-man Olyroos squad comprising 14 A-League players and nine based overseas for January's AFC U-23 Championship in Thailand.
The tournament serves as qualifying for next year's Olympic Games in Tokyo, with the top three teams joining hosts Japan as Asia's representatives.
The Olyroos will head to Kuala Lumpur for a training camp and friendly against South Korea before heading to Bangkok for the tournament.
"I am happy with the final make-up of our squad for next month's Championship," Arnold said in a statement on Monday.
"Over the past 12 months we have considered many players both at home and abroad as we've looked to grow the pool of players available to us.
"To finalise the 23 players for this tournament was no simple task - we had over 50 players on our radar for this tournament, so we will arrive in Thailand with a strong squad and one I believe will represent Australia well."
The Olyroos will play Iraq, Thailand and Bahrain in Group A of the tournament on January 8, 11 and 14 respectively.
There are four groups, with the top two teams from each advancing to the quarter-finals.
The two finalists and the winner of the third-place play-off all qualify for the Olympics. If Japan reach the semi-finals, the other three semi-finalists will all qualify, as Japan are hosts.
Melbourne City are the hardest hit of the squad's contributing A-League clubs, with four players - including regular starter Connor Metcalfe and goalkeeper Tom Glover - called up.
Adelaide United will be without talented forward Al Hassan Toure while Melbourne Victory defender Thomas Deng is also in the squad. Wellington will be without Reno Piscopo but impressive midfielder Cameron Devlin has not been called up.
Talented forward Daniel Arzani (Celtic, on loan from Manchester City), who has been on the comeback trail from a knee reconstruction, was not named.
Suspended quartet Riley McGree, Lachlan Wales, Nathaniel Atkinson and Brandon Wilson are unavailable for selection but if the Olyroos secure qualification, McGree will be eligible for the Olympics.
