Pakistan, the 1992 champion, retained the same lineup which finished off the pool stage with a win over Ireland at Adelaide last weekend.
Four-time champion Australia made one change to the lineup which beat Scotland in its last pool match, with Josh Hazlewood coming in for Pat Cummins in the pace attack.
Pakistan qualified for the quarterfinals with four straight wins after losing its opening two matches against defending champion India and the West Indies. Australia finished second to co-host New Zealand in Pool A with four wins, a tie and a one-wicket loss to the New Zealanders.
The winner will play India in the semifinals.
Misbah said the conditions might assist the seamers later in the day. Pakistan lost its first two games badly while chasing targets.
Australia captain Michael Clarke said the curators had left a bit of grass on the pitch, which could suit his pace attack early.
"I'm not that bothered to be honest," he said on losing the toss. "Looks like a beautiful wicket."
