The Caltex Socceroos have zoomed up FIFA's world rankings, surging up 17 spots to 50 in the latest rankings out today.

It's the first time Australia have been in the world top 50 since 2012, with the surge coming off the back of two big World Cup qualification wins in late March.

Ange Postecoglou's men defeated Tajikistan 7-0 in Adelaide and Jordan 5-1 in Sydney to confirm top spot in their group and progress to the final phase of qualifying for Russia 2018.

The Socceroos are now the second highest ranked team in Asia behind only Iran (42), ahead of next week's AFC Third Round draw which will take place in Kuala Lumpur on 12 April.

Australia's next opponents England, who they meet in a friendly on May 27 (May 28 Australian time) at the Stadium of Light have dropped one place to ten.

Argentina have reclaimed top spot surpassing Belgium, while there was plenty of movement among the world's top ten nations.
