Australia have flown Melbourne City winger Marco Tilio to Qatar as injury cover at the World Cup with Martin Boyle a doubt for the France opener with a knee problem.
Scotland-based Boyle is one of Graham Arnold's first-choice forwards but did not train with the squad on Tuesday.
"I think he’ll be alright, it’s just precautionary," his Socceroos teammate Cameron Devlin told reporters.
"Obviously, we don’t want to take risks. We’ve got the first game in a week ... but if he wasn’t to play it’d be a massive loss."
