Thousands of jubilant soccer fans took to the streets of Sydney and Melbourne in the early hours to celebrate Australia's nail-biting, last-gasp 3-1 World Cup win over Japan.
In Melbourne, about 6,000 fans packed Federation Square to watch the live coverage on the big screen.
In Sydney, more than 1,500 fans decked out in green and gold, with many in short-sleeved Socceroo jerseys despite near-freezing winter weather, gathered in front of the large screen at Circular Quay.
Car horns blared in the middle of the night. Nobody cared, as Australia suddenly became a soccer-loving nation.
In soccer-mad inner-city Leichhardt, Sydney police blocked off Norton Street as hundreds of fans gathered in bars and cafes to watch the Socceroos beat Japan and Italy take on Ghana.
Gloom had settled over the Australian fans as Japan took a controversial lead with what the referee later conceded was a goal he should have disallowed. The match looked set to end the Socceroos' World Cup hopes almost as soon as they had begun.
But with three goals in the last 10 minutes handing Guus Hiddink's men an historic World Cup win, Australian fans erupted.
"It was electric, the green and gold army was out in force. It was a good mix of diehard soccer fans and families," Jane Sydenham-Clarke said in Melbourne's Federation Square, where fans rugged up in blankets and sleeping bags.
Some residents in East Melbourne were kept awake until about 2.30am by the sounds of tooting horns and shouts of "Aussie Aussie Aussie" from those leaving the city, but overall, police reported a fairly quiet night.
In Sydney, fans poured out of the Circular Quay area after the victory, briefly bringing early morning traffic on George Street to a standstill.
Members of the Green and Gold Army also gathered at Ultimo's Agincourt Hotel which had set itself up as the unofficial headquarters of Socceroo fans.
In Leichhardt, fans who celebrated the Socceroos' victory had more reasons to cheer after Italy downed Ghana 2-0.
Police said the celebrations were mostly good natured and the crowds well behaved, although there were three arrests at Leichhardt overnight.
One a youth was arrested for firing a flare into the crowd, while two men were arrested for offensive behaviour, resisting arrest and failing to leave a licensed premises.
"Generally the people were well-behaved and the police were well prepared," said Detective Inspector Peter Bailey.
There were no arrests among the Circular Quay crowd.
"Everyone was really well behaved," a police spokeswoman said.
In Melbourne, pubs around the city reported big crowds and even the Japanese fans had fun, it seems.
Mark Tulloch, publican at the Imperial Hotel, said a crowd of predominantly Japanese supporters kicked on till about 2.30am.
Mr Tulloch said the hotel typically closed at 10pm on Monday nights, but stayed open until late to cater for about 150 people, most from the Australia-Japan Society.
"Everybody was happy," he said.
Melbourne police reported only one arrest, for drunkenness.
