The Caltex Socceroos put it all on the line in their make-or-break FIFA World Cup qualifying playoff games against Syria next month.
The good news for Ange Postecoglou is that some of his key players are bang in form.
The Caltex Socceroos star has been an ever-present for Huddersfield Town in their debut English Premier League campaign.
Mooy hasn't missed a minute of Town's first six games, during which they've lost just once to sit seventh on the ladder.
The influential midfielder has earned rave reviews from footballing pundits, even sparking comparisons with Manchester United legend Paul Scholes.
Having inked a club record five-year deal, the Australia stopper has quickly established himself as Brighton's number one.
In his most recent outing, Ryan was outstanding, keeping his second clean sheet of the season to earn the Seagulls a crucial 1-0 win over fellow promoted side Newcastle United.
Now firmly established as Australia's first choice goalkeeper, his performances against Syria will go a long way towards helping Australia progress to an intercontinental playoff.
A rusted-on member of Ange Postecoglou's starting side, the speedster is currently one of the hottest strikers in the German Bundesliga.
Having made an off-season move to Hertha Berlin, Leckie has been on fire, scoring four goals in six games so far, the latest a superb curling effort in a 2-1 win over Bayer Leverkusen.
Not surprisingly, the Caltex Socceroos star has made himself an instant hero with Hertha fans and may well be Australia's most important player in the games against Syria.
Another who made an off-season switch, the veteran attacker has quickly found his feet at German side Bochum.
Kruse has scored three goals in his last four appearances, including his club's second in an impressive 2-0 win over Ingolstadt.
Having now played 57 games for Australia, Ange Postecoglou will be relying on his seasoned front-man to cause havoc against the Syrian defence next month.
