"Just because we've qualified for the quarter finals, we're not going to rest," Cahill said after the game.
"We want maximum points, we want to win games,and we want to keep making an impact because we love the football, we love the style we're playing
"With Millsy (Mark Milligan) and Matty (McKay) coming in tonight, the way they moved the ball quick.
"The penetration of the pass, the way we we're getting in behind, they couldn't deal with the waves of pressure, they couldn't deal with our or fitness."
Cahill was substituted after 50 minutes, but said Australia's pressing style on the opposition wasn't tiring the players.
"It's not taxing, because the boys are fit, even for myself," 35-year old Cahill said.
"We've prepared to be like this, the fitness with the football and with the play.
"It's not what they (the opposition) expect. They expect to have the ball and play football.
"When you're tired, come off the park someone else will do it."
