Australia will play the biggest match of their lives when they meet reigning world champions Brazil in Munich at two am tomorrow morning (AEST).
After the Socceroos' heroics one week ago, Brazil will prove them with the biggest test they have ever had at a World Cup.
Australian coach Guus Hiddink believes his side will not be overwhelmed by the occasion, and will give the Brazilians a run for their money.
"This game deserves a team we think which is good enough to make (a game with) the opposition, and not just consider letting out all the players who are on yellow cards," the Dutchman said.
"We'd like to make a result. We'd like to make a good impression worldwide, and I don't think we have to think a lot of what will happen in the third game. We'll see then."
The Socceroos are full of confidence for tonight's encounter, after a positive result from its first ever World Cup game in 32 years, six days ago.
Australia's historic match against Japan was won 3-1, with the team scoring their first ever goal at the Championships, and winning their first ever game.
But more importantly, the Socceroos set the world alight with a moment of magic, coming back from 1-0 down through a dubious goal, to reply with three in the last six minutes of the game.
Midfielder Tim Cahill was the match winner with two goals, with the third coming from striker John Aloisi.
Also providing the Socceroos with confidence is Brazil's lacklustre performance against Croatia five days ago, where the South American outfit missed their distinct attacking flair.
Ronaldo and Adriano were unsighted for most of the game, whilst Ronaldinho showed flashes of brilliance but was far from his best.
Beating Brazil, or even getting a point from them will be difficult, however there are a few pointer coach Guus Hiddink will be hammering into his players.
Firstly, Australia must not fear their opponents. Like any other nation, the South Americans can have a bad day and are a beatable.
Secondly, the Socceroos cannot afford to defend for 90 minutes. Attack is the best form of defence, and Australia has the attacking prowess to trouble Brazil's ageing back line.
In attack, Australia may find it difficult to discover space playing through the middle. Hiddink will be looking for Scott Chipperfield on the left hand side, and Brett Emerton on the right, to provide crosses in from the flanks and use Australia's height advantage in Mark Viduka, Craig Moore and Tim Cahill, and possibly at a latter stage, Aloisi and Josh Kennedy, to get their goal.
However, Australia will struggle to keep the momentum flowing for the entire game and will need to close the gaps quickly when the South Americans gain the ascendency.
Hiddink has already instilled the ethos of "defend from the front", which will frustrate the Brazilians.
Ronaldinho will be the target man in midfield, and starving him of the ball should dry up service to the front man. However, Kaka is also just as deadly as his midfield partner, his sublime goal settled the contest against Croatia.
Their has also been hints laid Brazil will not go full throttle, simply as it might result in injury if they attempt to compete with Australia's physical style.
This may mean Brazil might try for an early goal, which the Socceroos are susceptible too, let the Australians come forward and try to score a second through a quick counter-attack.
However, whatever tactics are deployed in tonight's contest, it is a momentous occasion for Australian football, and a chance to prove they have truly arrived onto the world stage.
Australia's last group game will be against Croatia, to be played in Stuttgart on June 23, AEST.
