The Socceroos will wear special shirts during their warm-up for Friday's Asian Cup clash with Korea Republic and black armbands in the match, to raise awareness of the devastating floods in Queensland.
The shirts will read 'Australia Flood Relief Appeal - Donate now' and feature a link to the appeal website, Australian captain Lucas Neill said.
"Thanks to the Asian Football Confederation, who have gracefully allowed us to wear a different shirt in the warm-up, highlighting where you can donate to an appeal," said Neill.
"It's a massive disaster. Australian people have unfortunately died and people are missing. The floods are never-ending, people are losing their houses and it is a concern of the Socceroos team.
"Our thoughts and wishes are with the people back home and we hope we can do them proud over here."
Queensland state capital Brisbane, Australia's third-largest city, was turned into a disaster zone on Thursday, with whole suburbs under water and infrastructure smashed as the worst flood in decades hit 30,000 properties.
At least 15 people have been killed.
"This is not just for people in Australia, hopefully people all over the world can realise that sometimes football is not the biggest thing in the world and people's lives are more important,” continued Neill.
"People losing their families and their homes ... it makes football seem second best."
At least five members of the Socceroo squad were either born or raised in Queensland.
"We will be wearing black armbands for the people who have lost their lives," Neill added.
