An aggressive Australian side mounted a second-half fightback to record a surprise victory over an experimental German side in Moenchengladbach.
The robust Socceroos, coached by German tactician Holger Osieck, recovered from going behind to Mario Gomez's opener to exact some revenge for their four-goal rout in the group stages of the last World Cup.
A David Carney goal restored parity before a Luke Wilkshire penalty stunned the hosts to produce one of the shocks of the night.
Joachim Loew made eight changes from the win over Kazakhstan, including handing a debut to Borussia Dortmund's Sven Bender. His side began slowly against an Australian team, who looked to break up the play at every opportunity.
The first real sight of goal came from Australia's Brett Holman's first time volley on 18 minutes, which he struck well wide of Tim Wiese's goal.
The home side's initial chance arrived courtesy of a Lukas Podolski free-kick curled the wrong side of the post before they went on to take the lead.
After their first seriously threatening attack, the hosts began to grow in confidence and scored in the 26th minute with a beautifully worked goal, which symbolised the exciting football of this German side under Loew.
Thomas Muller's clever dummy allowed Andre Schuerrle to latch onto Sven Bender's through ball.
Schuerrle picked out Gomez and the Bundesliga's leading scorer found the top corner with a superb finish from just inside the penalty box.
Australia built up some pressure just before the break with three consecutive corners, culminating in a free header for Mile Jedinak, who could only direct the ball straight at Tim Wiese.
Podolski went close for the Germans moments into the second-half with a diving header after combining with Muller, whose link-up play was outstanding all evening.

Podolski regularly found space on the left-hand side and his fiercely struck shot on 57 minutes was cleared by Lucas Neill.
Australia surprisingly equalised just after the hour after a defensive slip from the normally reliable Mats Hummels.
Blackpool left-back David Carney played a neat one-two with Brett Holman before calmly stroking the ball under the body of Tim Wiese as the German defence opened up.
It was two in quick succession as the visitors then took the lead two minutes later from the penalty spot after Bender was penalised for clumsily tripping the lively Harry Kewell.
Luke Wilkshire, something of a specialist from twelve yards, sent the ball straight down the middle with Tim Wiese already committed to the dive.
Stunned by Australia's quick double strike, the home side pressed for an equaliser and it should have come in the 78th minute when Miroslav Klose spurned the chance to inch closer to Gerd Muller's goalscoring record, tamely shooting wide after escaping the clutches of Sasa Ognenovski.
However, Germany struggled to create and Australia held on for a fine victory.
The Germans are next in action at the end of May when they host fellow World Cup semi-finalists Uruguay in a friendly.
Australia's following encounter is a friendly with Serbia in early June.
