Mile Jedinak was proud of Australia’s “almighty effort” but felt the Socceroos “didn’t have the luck” as they went down 2-1 to France in their opening World Cup game.
VAR penalised Australia's Josh Risdon for a foul on Antoine Griezmann, allowing the Atletico Madrid forward to open the scoring from the spot, the first World Cup goal influenced by this form of technology.
However, French defender Samuel Umtiti handled Aaron Mooy's free-kick which enabled the Socceroos to equalise through Jedinak's penalty in Kazan.
The Aussies looked set to hold one of the pre-tournament favourites until Paul Pogba's lobbed effort deflected off full-back Aziz Behich and the crossbar to fall inches over the goal-line.
I can't fault the boys, it was an almighty effort today.
Jedinak was disappointed on the final whistle but confident of a good tournament from the Aussies.
He told BBC Sport: "We're disappointed, we didn't have the luck today.
“The second goal was fortunate for them, just over the line.
"We've got to take the positives though, pick ourselves up and go again.
"We knew we had to be right at it from the first whistle, maintaining discipline and focus. We got ourselves back into the game, we felt good. Then they got the goal, we gave it a go but it was not enough.
"I told my team-mates that if we maintain that structure and concentration we showed today, let's see where it gets us. I can't fault the boys, it was an almighty effort today."
