Aussies Nathan Burns, Trent Sainsbury and Erik Paartalu were all in action as the AFC Champions League group stage kicked off.
Australia defender Sainsbury played a full game for his new Chinese side Jiangsu Suning as they opened their group stage campaign with a 1-1 draw against 10-man Binh Duong.
Alex Teixeira - who produced this sublime piece of skill, Ramires and Jo all debuted for Jiangsu, the trio among a host of big-name players to have moved to the Chinese Super League in recent weeks - but they struggled to click against their Vietnamese opponents.
Jiangsu had not been in competitive action since the Chinese FA Cup success against Shanghai Shenhua in November and, despite leading through Ji Xiang 13 minutes in, Nguyen Anh Duc equalised from the spot before half-time.
Christian Amougou's late sending-off failed to inspire Jiangsu, allowing Jeonbuk Motors to go top of Group E with a 2-1 victory over FC Tokyo.
The 2006 champions got off to a winning start in the group thanks to goals from Ko Mu-yeol and Lee Dong-gook at the Jeonju World Cup Stadium.
Australia midfielder Paartalu played a full game for Jeonbuk Motors while fellow Australia international Burns came off the bench with 13 minutes remaining for FC Tokyo.
Seoul and Shandong Luneng are the early pacesetters in Group F - the former hammering 10-man Buriram United 6-0 thanks primarily to a four-goal haul from Brazilian striker Adriano.
Shandong Luneng sit second on goal difference after Diego Tardelli's late volley earned them a 2-1 win against Japanese champions Sanfrecce Hiroshima at the EDION Stadium.
Lokomotiv and Al Ittihad played out a feisty 1-1 draw in Group A's opening game as Sardor Mirzayev's equaliser a minute from time cancelled out Gelmin Rivas's first-half opener.
Jasur Hasanov and Fahad Al Muwallad were both sent off in the final stages as tempers flared in Tashkent.
Lokomotiv's draw allowed Iranian side Sepahan to move top of the table later as Luciano Chimba's brace ensured a 2-0 win over Al Nasr.
Group B also got under way as Zob Ahan edged Lekhwiya 1-0 in Doha to move top before Al Nassr produced a late comeback to draw 3-3 with Bunyodkor.
