Crestfallen captain Mile Jedinak was unable to disguise his disappointment after leading the first Socceroos team to return home from a World Cup campaign without gaining a point.
Australia, already eliminated from Brazil 2014 after honourable losses to Chile and the Netherlands, finished empty handed in their final match of Group B, going down 3-0 to Spain in Curitiba.
The Crystal Palace midfielder scored from the penalty spot during the Socceroos' thrilling 3-2 loss to the Dutch in Porto Alegre last week, but he was powerless to prevent the 2010 winners from picking his team apart at the Arena da Baixada.
"You can take some positives out of it. But overall, it's not what we wanted," he told SBS.
"Particularly with the positive performances in the first two games, even today, to get nothing from the games is quite disappointing to be honest."
"It's disappointing to finish the tournament the way we did. But ... we tried to impose ourselves on the game. (It) just wasn't there today. We let them get into those areas that we tried to keep them out of.
"You give them enough chances and they're going to score. I think it's unfortunate we didn't get anything but they're a quality side."
Asked if fatigue played in part in the loss to Spain, Jedinak suggested mental as much as physical tiredness may have taken its toll.
"Maybe a few lapses of concentration," he said.
"That's part of it, but that's the level you've got to be at. They're world-class players and you've always got to keep yourself in the game.
"When mistakes are made it's when you give the ball up. In transitional phase, that's when you get together, re-group and stay focused. Today, particularly for the goals, that wasn't there."
