The Socceroos backline stocks have been bolstered with Matthew Jurman returning to club action for the first time in six months following a knee injury.
The 28-year-old, who has four Australia caps - all from the 2018 World Cup play-offs - put in a full shift in Suwon Bluewings' 3-1 win over Gyeongnam FC in Korea's K-League on Wednesday.
The ex-Sydney FC man hadn't played for his club since he started in Suwon Bluewings' FA Cup semi-final defeat to Busan I'Park exactly six months ago.
Jurman underwent minor knee surgery earlier this year, although it was expected he'd return to action sooner.
The central defender was called into Bert van Marwijk's maiden Socceroos squad in late March to play Norway and Colombia, although he was released early from duty and didn't play in either match.
Jurman also missed all of Suwon's AFC Champions League matches, including both meetings with former club Sydney, although he was on the bench for their encounter in Korea earlier this month.
Van Marwijk stated Jurman's importance after missing the March friendlies, along with Trent Sainsbury who also didn't play due to injury.
''We have two important players who trained this week for the first time but still couldn't play, Jurman and Sainsbury. But yes, you can see we have problems when we defend,'' van Marwijk said after the 4-1 defeat to Norway in March.
''I hope that Sainsbury and Jurman stay fit and start to play in one or two weeks. We will work and search to nominate players who will make our defence better.''
Elsewhere, fringe Socceroos defender Tomislav Mrcela made his first club appearance since November as an 85th minute substitute in Jeonnam Dragons' 2-1 win over FC Seoul.
Kwabena Appiah played a full 90 minutes and provided an assist as Incheon United lost 2-1 to Ulsan Hyundai.

Elsewhere in Asia, Mitchell Langerak put in a full shift as Nagoya Grampus lost 3-1 at home to Shimizu S-Pulse in the J.League. Mitch Duke was a 76th minute substitute for the victors.
Milos Degenek was an unused sub for Yokohama F. Marinos in a 2-1 loss at Consadole Sapporo, while Ben Halloran was absent again for V-Varen Nagazaki in their 2-1 win away to Jubilo Iwata.
