With the series level at 1-1, the winner of the third ODI will take the series in addition to 10 vital points on the ICC Men's Cricket World Cup Super League.
After suffering a collapse in the second ODI to concede a game from an advantageous position for the second time on the tour, Australia will look to get their act right for the today's third and deciding match.
Towards that end, they will hope to be able to include Steve Smith after the star batsman missed the first couple of games over concussion concerns, having taken a blow to the head in training prior to the first ODI.
"He is definitely tracking in the right direction and we are hopeful he will be right for (Wednesday)," Langer told reporters in a video call. "He did all his running (on Monday), some high speed running, worked hard as part of the protocols. He has ticked every box at the moment."
England, while they should be delighted about their ability to bounce back from seemingly hopeless situations time and time again, will be keen to identify issues landing them in tough spots in the first place.
