Ryan McGowan will be doing everything in his power to push for Australia's starting side for the World Cup.
The Shandong Luneng defender is part of Ange Postecoglou's 30-man Socceroos squad for Brazil 2014 and although he knows his spot in the XI is far from certain, he is determined to work hard in training camp to give himself every opportunity.
"I will doing everything I can to impress in training, but even if you are not in the starting eleven your job as a player is to push those that are to make sure they are performing well," he said.
"You have to help each other out while at the same time also making it clear that if anyone slips up, or is not performing at the level the boss expects, then you are ready to step in and play well.
"There's a huge opportunity there for all the boys chasing spots at the back. Everything is up for grabs - it's a matter of coming into camp and showing what you can do."
The Aussie squad is currently in Gosford preparing for their May 26 friendly against South Africa in Sydney before they travel to South America to face Croatia in a pre-tournament fixture.
The first Group B match is against Chile in Cuiaba on June 13 ahead of the clash with Holland in Porto Alegre on June 18 which precedes the encounter with Spain in Curitiba on June 23.
