(CNN) -- Australia moved within one win of a place at the 2014 World Cup in Brazil after a commanding 4-0 defeat of Jordan in Group A of the Asian qualifying section.
Veteran midfielder Mark Bresciano opened the scoring after 15 minutes in Melbourne before New York Red Bulls' Tim Cahill doubled Australia's lead with a header just past the hour mark.
Winger Robbie Kruse, who recently joined Bayer Leverkusen, made it 3-0 with a fine solo effort, with captain Lucas Neill grabbing his first ever international goal to seal the rout.
The win means Holger Osiek's team will qualify for a third successive World Cup if it beats Iraq in its final Group B match in Sydney next week.
Iraq will have nothing to play for after a 1-0 defeat to Japan, who have already booked their World Cup slot. Shinji Okazaki scored the game's only goal in the final minute.
Third place will be determined by the clash between Oman and Jordan.
Whoever wins will face a two-legged playoff against a South American nation for a spot in Brazil.
South Korea are close to securing their place in South America after they won a crucial Group B game with Uzbekistan 1-0 in Seoul.
Both sides were level on points going into the game but an own goal from Akmal Shorakhmedov was enough to settle the outcome.
Iran capitalized on Uzbekistan's defeat, putting four goals past Lebanon to move into the second automatic qualification spot.
Strikes from Mohamadreza Khalatbari, Javad Nekounam, Reza Ghoochannejhad and Javad Nekounam settled the outcome.
South Korea now sit one point ahead of Iran at the top of the table, with the two playing next week to determine who goes through as group winners.
Uzbekistan are three points behind South Korea, but with a significantly inferior goal difference, and two behind Iran. Should South Korea beat Iran, Uzbekistan can qualify if they overcome Qatar.
Iran's success ensured Qatar, the World Cup 2022 hosts, can not now make it to Brazil.
Whoever finishes in third spot in Group B will also contest a playoff against a South American nation.
