Fuelled by an injection of young talent, the Socceroos' full-back positions are no longer such a problem area coach Ange Postecoglou.
Postecoglou has been vocal about his concern with the lack of depth on the defensive flanks, and as a result has been busily shuffling the deck in search of a solution.
Left-backs Jason Davidson and James Meredith and right-backs Tarek Elrich and Ivan Franjic are just a few players to have come and gone.
But the recent arrivals of Brad Smith, Jason Geria and Alex Gersbach have been timely, and Postecoglou felt they added quality to a set-up already featuring Ryan McGowan and Josh Risdon.
Right-back Geria, 23, impressed on international debut in Saturday's 1-0 friendly win over Greece while 19-year-old left-back Gersbach used his 10-minute debut off the bench to grab the match's only assist.
"In terms of the full-back positions, there's certainly encouragement there that we're getting more depth," Postecoglou said.
"The players we've introduced in the last couple of camps have really shown that they understand how we want to play our football, and have looked comfortable within the environment.
"I'm certainly a lot more satisfied with those areas of the park than probably I was six months ago."
While the Socceroos' attack is still a work in progress, the future is bright for Australia's defence - already-consummate midfield aside.
That was on show on Saturday at ANZ Stadium, where the a backline with only 26 caps between them more than held their own against Greece.
Centre-back Trent Sainsbury was the oldest and most experienced at 24 and with 15 caps, alongside composed 22-year-old Milos Degenek, while Smith and Geria played out wide.
"The age factor, I didn't even think about it until after the game," Postecoglou said.
"It was Trent who told me because he was the oldest one out there and he looked at the backline probably scratching his head about what I'm doing.
"But the same way I don't look at Tim Cahill's age I don't look at the young ones' age - that's just a number for other people.
"We're looking at players who can contribute to us.
"It's about bringing in people we think will add to what we're doing."
