Luke Brattan and Tommy Oar earn Socceroos recall for Thailand WCQ

Luke Brattan and Tommy Oar are among seven new faces in an extended 30-man squad named by Socceroos coach Ange Postecoglou for next month's World Cup qualifier against Thailand.

All 23 players who were part of the squad that drew with Saudi Arabia and Japan have been recalled, along with Brattan, Oar, Josh Risdon, Jason Geria and the overseas-based trio of Nathan Burns, Milos Degenek and Aziz Behich.

Postecoglou will trim the squad back to 23 after watching this weekend's matches, effectively challenging the seven new faces to show why they deserve to survive the cut.

"We have players who are in the squad or on the fringe, including those playing in the A-League, that are just starting their seasons and with the tight turnaround from Japan to Thailand I wanted to have another look at them after they have showed good signs in the opening rounds," Postecoglou said.

"It is yet another good sign of the depth we are creating and when we announce the team after this weekend there will be players who miss out that are playing well enough to be part of the squad."

Brattan, who was part of a Socceroos camp last year but failed to win a cap, has made a strong start to the A-League season with new club Melbourne City while Brisbane Roar winger Oar has not made a national team appearance for nearly 12 months.

The duo are among five A-League players in the squad, along with Perth Glory's Josh Risdon, Melbourne Victory's Jason Geria and City's marquee star Tim Cahill.

Risdon, Geria and Degenek all play at right-back, which has recently emerged as a problem position for Australia.

The inclusion of Burns, who was left out of the last Socceroos squad, comes as no surprise after Postecoglou name checked him earlier this month as one of few players capable of challenging Mathew Leckie and Robbie Kruse for a wing spot.

Left-sided defender Behich, meanwhile, is in line for his first Socceroos involvement since last year's 2-1 win in Kyrgystan.

The Socceroos are second in Group B and cannot afford to slip up against a winless Thailand, whose chances of World Cup qualification for Russia 2018 appear shot.

The clash in Bangkok will proceed as planned despite the recent death of Thailand's king, although supporters have been asked to treat the match as a solemn occasion.

"We will be in Bangkok for a longer than usual period as we only have one match in this window so we will have a good lead in to ensure we are well prepared," Postecoglou said.

Australia squad: Aziz Behich, Luke Brattan, Nathan Burns, Tim Cahill, Milos Degenek, Adam Federici, Jason Geria, Alex Gersbach, Apostolos Giannou, Craig Goodwin, Chris Ikonomidis, Jackson Irvine, Mile Jedinak, James Jeggo, Tomi Juric, Robbie Kruse, Mitchell Langerak, Mathew Leckie, Massimo Luongo, Ryan McGowan, Mark Milligan, Aaron Mooy, Tommy Oar, Josh Risdon, Tommy Rogic, Mathew Ryan, Trent Sainsbury, Brad Smith, Matthew Spiranovic, Bailey Wright.
