Sure, there's no bigger test than playing Brazil in Brazil but the the Samba Boys ran rings around the Socceroos, or more accurately danced rings around them, dominating in every aspect of the game at the Mane Garrincha stadium.
The Socceroos had next to no possession and when they did have the ball they just couldn't keep it as they were left completely outclassed.
Jo scored a brace with Barcelona superstar Neymar, Chelsea's Ramires, Alexandre Pato, Luiz Gustavo adding the others as the Socceroos' hapless defence were unable to stem the barrage.
It was a particularly rough day for centre-half paring Lucas Neill and Sasa Ognenovski along with defenders Ryan McGowan and Matt McKay, who were left dumbfounded by the brilliance of the South Americans.
Young guns Tom Rogic and Mitchell Duke were given game time late in the piece with coach Holger Osieck, who also brought on veteran Archie Thompson, desperate to add firepower up front.
But it proved too little too late.
Former Manchester City striker Jo was the first to get one past Mark Schwarzer just eight minutes in after cleaning up a Bernard rebound off the post.
With Australia's height advantage, their best chances were always going to be aerial ones and sure enough Josh Kennedy, who's memorable header against Iraq in June secured Australia's ticket to the World Cup, got on the end of a Tommy Oar corner to rise high again with his header this time going just over the cross bar.
Neill also had a chance with a header but also sent in over while Brett Holman provided the only other glimmer of hope with a weak shot on goal in the second half.
Bernard proved to the thorn in Australia's side with another great run down the right and combined with Jo again to give him his second in the 34th minute.
Barcelona star Neymar's crafty skills were on full display as he easily weaved past three defenders to slot past Schwarzer a minute later to race to 3-0 after just 35 minutes to send the crowd of over 40,000 into raptures.
Ramires continued the assault in the second half, getting on the end of a cross from Paris Saint Germain left back Maxwell, to put one past his Chelsea teammate Schwarzer.
Pato was the next to get one into the back of the net adding to the tally to make it 5-0 in 72 minutes.
And just when you thought it couldn't get any worse, Gustavo provided possibly the goal of the match with a superb chip into the top left hand corner in th dying minutes.
