Australia fly-half Quade Cooper said the Pool A fixture against Uruguay at Villa Park on Sunday would be an important litmus test for him and coach Michael Cheika.
During Australia's opening World Cup fixture against Fiji, earlier this week, Cooper did not feature in the Wallabies plans, as Bernard Foley started at pivot. However, Cooper will start this weekend and it will be critical that he makes a statement.
Cooper was not outstanding during the previous World Cup and the most crucial element at this juncture will be to earn the trust of team management.
"To be honest, the way we look at it is that every day is a way to audition for the team," Cooper told journalists this week.
"Every day you turn up to training, we're putting ourselves in positions where we're challenging each other for starting positions – every single player.
"Whether you get your opportunity in the game, you have to be ready to take that," added Cooper.
Cooper emphasised that this weekend would be about exploiting the opportunities that are presented to him, adding that he was ready to do just that.
"If you don't put your best foot forward and don't do a good job at training, then how do you expect to get a start in a game?"
It is also important that he does not take his exclusion from the first World Cup match to heart – mental strength will be just as important this week.
"We're all here as a team to do the one job, which is to win the World Cup," he said.
"The overall (goal) is to win the World Cup – not to play in games or be the guy who said 'I started every game at the World Cup'.
"We're here to win it and whether someone else gets the opportunity to start, we've got to support them and the coaches in their decisions to start guys and have faith in each other to get the job done.
"This week, I get an opportunity so I have to go out there and get the job done not only for myself but for my teammates and all of the supporters back home to make sure this team can keep winning."
