Midfielder Matt McKay says the Socceroos are not at the World Cup to make up the numbers and want to prove the football world wrong.
A year ago McKay was in China with Super League club Changchun Park, and now he is set for his first World Cup after a terrific A-League season with Brisbane Roar.
The 31-year old said the Socceroos want to make Australia proud of them with their performances in Brazil.
"Twelve months ago I was still in China so to come back and win the double for Brisbane is special and then a World Cup - so good times," McKay said.
"But we’re not here to make up numbers. We want to prove some people wrong and everyone’s written us off, so we’ve got nothing to lose.
"We’ll be brave and get out there and make Australians proud."
McKay is unlikely to start against Chile on June 13 but is unfazed.
"I’m a happy guy," he said.
"I can do whatever role. I’ll support the starting XI and whenever my chance comes, whether it be off the bench or starting in the future, I’ll be raring to go.
"We’ve got a capable team. Everyone knows their roles and the flipside is everyone in the second XI knows their roles, which is great.
"You need that pressure but also when players do go down, like in some of these last friendlies, that people are ready to come in."
McKay, who made his Socceroo debut back in 2006 but missed selection for the 2010 World Cup, said it would be special to get some game time in Brazil at some stage.
"For a Brissy boy, a small Brissy boy to go to a World Cup, everyone wants to be involved," he said.
"Hopefully I get some games but we’ll see what is best for the side."
He added: "I’m old enough and wise enough and ugly enough to roll with the punches.
"I’m delighted to be a part of this squad. I played in 13 of the 14 qualifying games, it would have been disappointing not to come like a few of those boys who missed out."
McKay is signed to Roar as the club’s Australian marquee until the end of the 2014-2015 season and the former Olyroo and Young Socceroo said he is happy staying in the domestic comp.
"I’m delighted with the A-League," McKay said.
"Back in Brisbane especially, it’s a special team, a special group of players and a special club for me.
"But I want to get better. I want to improve my game and take it to the next level."
