World Cup hopefuls Oman twice led at the ANZ Stadium in Sydney against the Socceroos but goals from Tim Cahill and Brett Holman brought the teams level.
The 2-2 draw puts Australia and Oman joint second on six points behind leaders Japan, with Australia having a game in hand.
The result in Sydney gives Iraq, who are in fourth place with five points, a window of opportunity, if they can get something from their last three games against Oman, Australia and Japan.
Jordan play Japan later today, and could get themselves back into the contention with a victory over Alberto Zaccheroni’s men. A win for Japan would see them become the first nation to qualify for the 2014 World Cup.
