Australia's goals were scored by Tom Rogic and Tomi Juric. Both are in the prime of their careers, and although they have only two caps each for Germany, a total of almost 400 combined appearances in the Bundesliga means they know exactly what it feels like to play football at the highest level.
The match in Sochi will be the sixth time that the two nations have faced one another, but while Germany won the first three, Australia have recorded a win and a draw in the last two contests.
"Second half was better, we composed ourselves a little bit, we were smarter defensively and good with the ball. But if we play the way we know we can, we can definitely beat them".
Germany face Group B leaders Chile on Thursday evening (8pm) in Kazan, while Australia take on bottom club Cameroon (4pm).
Germany is one of the strongest teams in world football, and are also looked upon as favourites to win the ongoing Confederations Cup in Russian Federation.
Dominant in possession, Germany were rampant in attack as they carved through Australia's three-man defence at will but with thanks to some profligacy, were unable to make their domination count.
Australia was outplayed in their last global friendly at home by Brazil, and they will be looking for a better performance against Germany. "We need to work on maintaining our stability. but this is a new team and things have worked very well".
Although Leon Goretzka extended the German lead three minutes into the second half, another blunder by Leno ensured it was a nervy conclusion to the game in the Black Sea resort.
Australia made it 3-2 when Juric tapped home from close range after Germany goalkeeper Bernd Leno failed to hold a deflected Rogic shot on 56 minutes.
Dufner didn't shrink when Memorial victory appeared out of reach
Defending champion William McGirt followed his opening round 71 with a 72 which leaves him on one under, 13 shots off the pace. He tried to play a flawless shot and barely got it out, then chipped down to 5 feet and missed the putt, making double bogey.
"They have young players but there is pressure on them to do well".
Australia is taking the trip to Russian Federation far more seriously, bringing a full-strength squad unlike Germany.
After last Tuesday's 4-0 drubbing by the Selecao in Melbourne, head coach Ange Postecoglou expects Germany's young guns to prove themselves in Sochi.
Germany's rawness wasn't obvious at all early in the game when a goal was created after only five minutes.
Parity, though, was only in place for around two minutes.
An out-of-sorts Massimo Luongo lunged at man-of-the-match Goretzka in the box and Draxler's penalty ensured Germany went into the halftime break ahead once more.
It was extended further three minutes into the second half.
With a record 48-goals for the Australian side, Cahill will look to add to his worldwide goal-scoring tally against the world champions.
