The Caltex Socceroos have dropped one spot in the latest FIFA rankings released on Thursday night (AEDT), sitting in 37th spot.
While there was little movement in the top 50 due to a lack of international action over the last month, Australia have fallen behind Romania.
But with matches against Norway and Colombia to come later this month, Bert van Marwijk’s side have the chance to jump back up the rankings with a couple of positive results.
The Caltex Socceroos’ opponents at this year’s FIFA World Cup in Russia remain near the top of the rankings having stayed the same from last month.
France sits inside the top 10 at ninth, with Peru two spots further back at 11 and Denmark are 12th.
Australia’s opponents in March’s friendly Colombia remain in 13, while Norway has fallen one spot to 57th after being leapfrogged by Burkina Faso.
Iran remains Asia's top-ranked team, having stayed at number 33 to sit just above the Caltex Socceroos.
Japan (55) are also unchanged but Korea Republic (59) have dropped one and China are up three places to 65 to round out the top five of the AFC nations.
Elsewhere, world champions Germany held on to the top spot, ahead of Brazil, Portugal, Argentina and Belgium in an unchanged top five.
