The Socceroos progressed from their initial phase of qualifying by topping their group, which consisted of Jordan, Tajikistan, Bangladesh and Kyrgyzstan.
However, this will be a much tougher test for coach Ange Postecoglou's men.
Postecoglou, who attended the draw in Kuala Lumpur, said his side is ready for the challenges ahead in their final round of qualifying for Russia 2018.
"It’s good to know the draw so we have a clear picture of what is in front of us from a football and logistics perspective to qualify for the World Cup," Postecoglou said.
"Over the last two years we have built up a very strong portfolio of information on most Asian nations and its players by having scouts at matches and tournaments all over Asia so the players go into every match well prepared. That information will be sharpened and expanded now we know that we face Japan, Iraq, UAE, Saudi Arabia and Thailand.
"As Champions of Asia we will show due respect to all countries but focussed on continuing our journey that has aspirations greater than simply qualifying for the World Cup."
