Wild scenes unfolded in the stadium crowd, in bars across the globe and in Melbourne’s Federation Square.
But in footage captured by the BBC, Graham Arnold’s joy very quickly turned into a white-hot rage.
The Socceroos coach celebrated briefly before he vented his frustrations in the direction of skipper Mat Ryan.

Arnold was seen pointing and screaming at the goalkeeper, shouting at him to go and celebrate with his teammates.
The moment from the Socceroos manager shows just how much he wants the team to be truly bonded.
IS ARNIE HERE TO STAY?
Arnold has the backing of the playing group to continue as national coach regardless of Australia’s final destination at this World Cup.
Arnold became the first Australian-born coach to win a World Cup game when he helped steer the Socceroos to victory over Tunisia on Saturday, a result which put them in the box seat to reach the Round of 16 for just the second time in history.
Throughout his four-year tenure in charge of the Socceroos, however, Arnold has always faced outside pressure.
But never from his players.
On Sunday, still basking in the glow of Australia’s 1-0 win, striker Mitchell Duke threw his support behind Arnold by declaring “every lad in this team would like to see him continue on”.
“That’s completely on him to see if he wants to continue on but for me personally I have obviously loved working under Arnie,” said Duke.
“I love the way he coaches, I love the atmosphere he creates in camp and if that’s what he wanted to do, to continue on, I back him 100 per cent. But that is obviously an individual thing for him.
“He has been doing it for this whole journey, it has not been easy, but I am sure every lad in this team would like to see him continue on.”
Football Australia have been noncommittal on the future of Arnold, whose current contract runs out after the end of the 2022 World Cup, preferring to wait and see on the results in Doha.
It is unclear whether Arnold would pursue another contract, however his strong bond with the playing group could convince him to accept an extension if one were offered.
Speaking before the all-important Tunisian victory, Arnold stressed “it’s not about me”.
“It’s not about me at all. If it was about me, I probably would have left ages ago,” Arnold said.
