Australia coach Bert van Marwijk was left stunned by his side's inability to score a winning goal against Denmark as they were held to a 1-1 draw in their second Group C match at the World Cup.
The Socceroos fell behind to a wondrous strike from Christian Eriksen, before equalising when Mile Jedinak converted a penalty for the second game in a row.
Van Marwijk's side improved significantly in the second half, but suffered frustration as they chased a goal that would have significantly boosted their hopes of qualifying for the round of 16.
"It's unbelievable and a pity we didn't score more," Van Marwijk told a news conference, assessing his side's failure to score again.
"In the first 15 minutes we were a little bit restless but after that we started to play football and had confidence on the ball. We controlled big parts of the game and in the second half we created chances."
Australia's draw means they will need to beat Peru in their final group match to have a chance of prolonging their World Cup campaign.
Van Marwijk suggested teenager Daniel Arzani could be called upon to start against Peru.
"Everybody knows he's a big talent but he hasn't played so long in Australia. It's an exception that I named him in the squad but I trust his qualities," he said of the 19-year-old.
"He has to learn a lot but he's very talented and an intelligent player. I think it's good for him to play 25 minutes today. We will see for the next game if he starts."
Australia are set to be without striker Andrew Nabbout, who was hurt against Denmark.
"Andrew has a bad shoulder injury, I think the tournament is over for him," Van Marwijk added.
