Short picked up a quad injury against Afghanistan and would not have had time to recover for the knockout matches.

Connolly, the 21-year-old left-hand batter and left-arm spinner, has been a traveling reserve with the squad so will be available immediately. He has played just three ODIs but could come straight into selection consideration given Australia have lost Short's offspin.

Fraser-McGurk, who himself was a replacement for Mitchell Marsh, has struggled in his seven ODIs to date with 98 runs at 14.00, looking vulnerable when the new ball moves, but the selectors still see him as a player who can take on the powerplay.

If Fraser-McGurk isn't the route taken by the selectors it will require someone from the middle order moving up to the top to fill Short's role, potentially the in-form Josh Inglis.

Australia learnt their opponents for the semi-final will be India in Dubai on Tuesday when New Zealand were beaten in the final group game.

Both Group B sides who qualified - Australia and South Africa - traveled to Dubai so that the team who faced India would have time to prepare. South Africa will now head straight back to Lahore for their semi-final against New Zealand.

Australia were troubled by Sri Lanka's spinners in their two ODIs in Colombo prior to the Champions Trophy.

"It changes a little bit," Zampa said of the conditions between Pakistan and Dubai. "Potentially slower lower wickets, so there might be an opportunity to create a few more chances, we'll see."

Zampa added he felt there was room for improvement in his own bowling after returns of 2 for 64 against England and 2 for 48 against Afghanistan.

"Personally, I don't think I'm bowling quite at my best, but I like to think the beauty about me is when I'm not quite at my best and not feeling that great out there is my ability to still contribute and take those big wickets," he said.

"I'm obviously working on some stuff at the moment to hopefully get back to my best, but as I said, the ability to still do a job for the team and get those big wickets is still there, which to me is really important."
