Here's everything you need to know ahead of Australia's 2018 FIFA World Cup qualifier against United Arab Emirates in Sydney on Tuesday night.
AUSTRALIA v UNITED ARAB EMIRATES, March 28, Allianz Stadium, Sydney, 8pm (AEDT)
World ranking: 55
Coach: Ange Postecoglou
Captain: Mile Jedinak
Qualifying route: Finished top of Group B (7 wins, 1 loss)
World Cup record: Four appearances (1974, 2006, 2010, 2014)
Third-round qualifying results so far: Australia 2-0 Iraq, UAE 0-1 Australia, Saudi Arabia 2-2 Australia, Australia 1-1 Japan, Thailand 2-2 Australia, Iraq 1-1 Australia.
Key man: Jackson Irvine - In his first Socceroos start, the 24-year-old was the chief beneficiary of Postecoglou's tactical switch-up in Tehran.
Now Irvine must continue his good form given Tom Rogic's injury and Aaron Mooy's suspension.
In a nutshell: No one in the Socceroos set-up misunderstands the importance of Tuesday's match. Win, and Australia are every chance of qualifying directly from the group, while putting breathing space between themselves and fourth-placed UAE.
Anything short of a win will leave qualifying hopes out of the Socceroos' own hands.
UNITED ARAB EMIRATES
World ranking: 68
Coach: Mahdi Ali
Captain: Ismail Matar
Qualifying route: Finished second in Group A (5 wins, 2 draws, 1 loss)
World Cup record: One appearance (1990)
Third-round qualifying results so far: Japan 1-2 UAE, UAE 0-1 Australia, UAE 3-1 Thailand, Saudi Arabia 3-0 UAE, UAE 2-0 Iraq, UAE 0-2 Japan.
Key man: Omar Abdulrahman - The Asian player of the year is a gifted playmaker with a terrific eye for a pass and technical quality.
Australia's answer could be to starve him of time on the ball by deploying Mile Jedinak to pay close attention.
In a nutshell: After starting with a bang - an away win over Japan - the Emirati have suffered three losses in five matches and will find themselves well off the pace with another defeat in Sydney.
Australia should expect full-blown effort from their opponents.
Australia have never lost or conceded a goal to the UAE, winning two and drawing two of their four meetings.
The two countries met last September in Abu Dhabi, where substitute Tim Cahill's late volley earned Australia a crucial qualifying win on the road.
