The Socceroos are stepping into the unknown as much as any side with a new crop of eye-catching attacking talents playing alongside a more experienced midfield and defensive core. Qualification for a sixth consecutive World Cup was sealed without needing to tread carefully through the playoffs for the first time since 2014, but only after a change of direction when Tony Popovic replaced Graham Arnold as the head coach.

The renowned disciplinarian demanded a greater physical intensity and defensive zeal in all areas of the field, with results quickly improving and building into an eight-match unbeaten run that locked in a World Cup spot. The Socceroos have suffered from mixed fortunes since then as Popovic has cast the net wider to give opportunities to fringe players and the next generation.
