Australia head coach Ange Postecoglou has named a 30-man squad for two 2018 World Cup qualifiers this month.
The squad will be trimmed to 23 after this weekend's matches, with players being given one final chance to impress the Socceroos boss.
“We have named an extended squad with a few notable returns but we will make a final decision after this weekend’s matches around Australia, Asia and Europe,” Postecoglou said. “With the Asian leagues and some countries in Europe only just starting I wanted to have another look.
“There is also recognition for some players who have been in good form in the A-League and have the characteristics to fit in with some of our experienced players as we move into an important stretch of qualifying."
Australia will face Iraq on March 23 in Tehran and the UAE on March 28 in Sydney.
