Australia have reverted back to playing with five specialist bowlers for their Twenty20 World Cup clash with England, bringing back Ashton Agar after losing the toss and being put in to bat.
Captain Aaron Finch confirmed that Agar would come into the side for the crunch clash, with Steve Smith listed to bat at No.3 and Mitch Marsh dropped.
It comes after Australia's reliance on allrounders to make up four overs was exposed against Sri Lanka, with Glenn Maxwell and Marcus Stoinis going for a combined 51 runs.
England are unchanged.
The winner of the two so-far undefeated teams in Dubai will go close to locking in a semi-final spot.
But Australia's task has been made no easier by the result of the toss, with Finch's men asked to defy the trend of the World Cup by batting first.
Chasing teams have now won 12 of 13 matches so far in the group stages of the World Cup, with due becoming a big factor.
Australia XI: Aaron Finch (capt), David Warner, Steve Smith, Glenn Maxwell, Marcus Stoinis, Matthew Wade, Pat Cummins, Ashton Agar Mitchell Starc, Adam Zampa, Josh Hazlewood
England XI: Jason Roy, Jos Buttler, Dawid Malan, Jonny Bairstow, Eoin Morgan, Liam Livingstone, Moeen Ali, Chris Woakes, Chris Jordan, Adil Rashid, Tymal Mills
