The Socceroos qualified for the World Cup warm-up tournament by winning the Asian Cup in 2015 to be crowned Asian champions.
Federation Internationale de Football Association took notice and decided that a tournament featuring the champions of each confederation was an opportunity to make money, primarily by bundling the TV rights to the tournament with those to the World Cup.
The team's performances in Russian Federation this week will therefore set the tone for the remainder of Postecoglou's tenure - the manager has already signalled that he will step down when his contract expires in July 2018. Thus far, the Socceroos' coach has shown a complete unwillingness to waver from his all-out attacking ethos. Another opportunity missed for Germany as Australia's defense was all over the place and Brandt then had a long-range effort pushed away by Ryan.
Manchester City's Leroy Sane will not feature at the tournament, though, after the pacey winger pulled out of the squad to undergo a surgery on his nose.
And Australia, ever persistent, made them pay with a goal out of nowhere.
They were pegged back against the run of play five minutes from the break, however, as Celtic's Tom Rogic took advantage of a fortuitous bounce to volley that Leno allowed pass through his fingertips.
For the most part, Australia looked defensively frail, remained largely rudderless in attack and disjointed throughout the spine.
Germany took the lead in just the fifth minute.
Germany got off to the flawless start as they went 1-0 up in the fifth minute through Stindl who smashed in a superb cutback from the right.
"(But) there's no doubt it's a team full of character and courage.
"Robbie Kruse or Mathew Leckie are really fast players and we know them from the Bundesliga".
"It's a loss and the loss falls on me, it's my responsibility".
There's even a school of thought saying "Die Mannschaft" is better off including younger, hungrier players.
With a record 48-goals for the Australian side, Cahill will look to add to his global goal-scoring tally against the world champions. But in the closing moments of the opening half an ill-advised lunge by the Tottenham academy product Massimo Luongo led to a penalty.
While some may argue that Germany should've been less generous in letting the opposition score, what matters is that they still managed to out-class Australia and brought themselves back in the game and Draxler has truly proven that he not only talented but also a good leader under pressure.
But Australia eventually bounced back, Tom Rogic finding the net with a lovely strike from distance and Tomi Juric picking up the scraps of a free-kick. From that point of view I'm always proud of them.
But Germany were by no means in control and a blunder by Bernd Leno gifted Tomi Juric a tap-in to make it 3-2, setting up a nervy finish. The Aussies will be familiar with Chile's style of play, who they faced in the World Cup three years ago.
"Three tournaments in three years is borderline", Low told reporters, referring to the 2014 World Cup and last year's European Championship.
