Some poor recent results have seen Australia's national team continue to suffer in the world standings, with the heavy defeat to Brazil the latest blow
The Socceroos have slipped seven spots to 53rd in the latest FIFA world rankings as pressure continues to mount on coach Holger Osieck.
Australia, who failed to win a game at July's East Asian Cup in South Korea, were woeful in a 6-0 friendly loss to Brazil in Brasilia last Sunday morning [AEST].
With the 2014 World Cup less than 12 months away, Osieck is facing an uphill battle to keep his job, and next month's friendly against France in Paris seen by many as the German's last chance to make amends for the poor results.
Meanwhile, Argentina have climbed to second place in the rankings after clinching qualification for the World Cup on Tuesday.
Alejandro Sabella's men made sure of their place at Brazil 2014 with an emphatic 5-2 win over Paraguay in Asuncion, Lionel Messi scoring a double as the two-time winners cruised to victory.
That success has seen them rise above Colombia and Germany and into the top two, with holders Spain remaining at the top following a victory over Finland and 2-2 draw with Chile.
Cesare Prandelli's Italy are up into fourth following a 2-1 victory over Czech Republic, which secured their place at the World Cup.
Belgium are on the brink of qualification after a comfortable 2-0 success against Scotland.
Marc Wilmots' men have yet to lose in their qualifying campaign so far, and they now sit in their highest ever position in the rankings after jumping four spots to sixth.
Uruguay are one place behind them, climbing back into the top 10 courtesy of a 2-0 win over Colombia, with Brazil up to eighth thanks to friendly wins over the Socceroos and Portugal.
Netherlands are among the fallers, Louis van Gaal's men, who were held by Estonia on Friday, dropping four places to ninth despite clinching their place in Brazil with victory over Andorra on Tuesday.
The United States will be at the World Cup finals for the seventh consecutive time following their 2-0 win over Mexico.
Jurgen Klinsmann's side have risen six places to 13th as a result of that triumph, while Costa Rica, who ensured their spot at the finals with a 1-1 draw with Jamaica, are up from 39th to 33rd.
England have dropped to their lowest ranking since 2001, falling to 17th despite holding on to top spot in their qualifying group with a win over Moldova and a draw against Ukraine.
Meanwhile France, who appear destined to face a play-off in order to reach the finals, are down to 25th. The 1998 champions slipped to their lowest ranking since 2010.
South Korea, the lowest-ranked team to have qualified for the World Cup, sit 58th after dropping two places following a defeat to Croatia on Tuesday.
