Glenn Maxwell is a doubt for Australia's opening ODI against Pakistan in Sharjah but Nathan Lyon should be available for the match.
The all-rounder missed training on Wednesday due to illness, a day after Lyon had been absent for the same reason.
Australia expect Lyon to be fit for Friday's opening clash and he could be picked in a dual spinning assault with wrist spinner Adam Zampa.
Captain Aaron Finch said of the conditions: "The stats from here all suggest that spin has a bigger impact. I'll expect them to spin.
"We even saw yesterday the training wickets looked how we expect the middle to play. You're never quite sure though, once there's a bit of traffic on it they start to slow up pretty quick and spin a bit."
Australia have pace bowler Nathan Coulter-Nile available again for the five-match series after he missed the final three ODIs against India to fly home to Perth for the birth of his second child.
Coulter-Nile said there was a good mood around the squad ahead of the World Cup.
"Everyone's performing, that's why we're winning but even when someone has a bad day, they're really supportive of other blokes who have had a good day," he said.
Pat Cummins was restricted to gym work on Tuesday and is expected to be rested at some point during the series in the UAE.
Selectors will meet early next month to settle on the 15-man World Cup squad, with Zampa in contention for a place.
The spinner said: "Throughout my short career I've found it can change really quickly. I started my career really well but I've had some ups and downs.
"I know what it's like to be in and out of the team and be dropped from the squad altogether, so I am just trying to make the most of my position."
Australia are 4/7 to win the first ODI against Pakistan, who are 11/8 to come out on top. Meanwhile, Australia are 4/1 to win the 2019 Cricket World Cup.
