Coach Holger Osieck defended his decision, saying he was "opening doors to talent" that caught his attention in a bid to test upcoming players at international level. The squad includes newcomer Jackson Irvine, 20, while Oliver Bozanic, son of former Socceroo Vic Bozanic, received his second call-up after debuting in August 2009.
Mathew Leckie and Nikita Rukavytsya, who both play for FSV Frankfurt, also return to the squad, along with defenders David Carney and Jason Davidson and forward Dario Vidosic. Striker Tim Cahill and defender Luke Wilkshire are both included after recovering from injury, but fellow veteran Schwarzer, 40, has been omitted with Mitchell Langerak and Mat Ryan included as goalkeepers.
"I know what he (Schwarzer) can do and his status in the team, he is our number one goalkeeper," the coach told a press conference. "(But) if I keep playing him, what about the others? In particular Mitchell Langerak, he deserves a minimum of one game at least, because he was a very good servant to our team."
Schwarzer is on a one-year contract with English Premier League giants Chelsea which runs until the 2014 World Cup in Brazil, where the veteran keeper will hope to add to his more than 100 caps after Australia qualified for the tournament in June.
Osieck said he had spoken to Schwarzer, who he said was going to play in a League Cup game against Swindon in coming days. "Hopefully he's going to be a regular (starter) again... you never know, injuries can happen," he said.
