Australia's ODI squad has been significantly impacted by injuries, with batting allrounder Matt Short and fast bowler Lance Morris both ruled out due to injuries. Short is dealing with a side injury sustained ahead of the Caribbean T20 series, while Morris is sidelined with lower back soreness.

Morris, who has limited international appearances due to injury and form issues, was only part of the ODI squad and has now been sent home to investigate his back soreness.

Matthew Short was also released from the squad after not fully recovering from a training injury that previously sidelined him, and he plans to manage his injury during the domestic season.

The injuries and health issues have led to the exclusion of three key players from Australia's white-ball series against South Africa, prompting significant squad changes.

In response to these setbacks, Australia has added Matthew Kuhnemann and Aaron Hardie to the ODI squad as replacements for the injured players.

The updated Australian ODI squad now includes Mitchell Marsh as captain, along with Xavier Bartlett, Alex Carey, Cameron Green, Nathan Ellis, and Marnus Labuschagne, among others.

The T20 series against South Africa is set to conclude with a match in Cairns on Saturday, after which the three ODIs will commence starting next Tuesday in Cairns and Mackay.

Australia won the first T20 match in Darwin, but South Africa leveled the series with a win in the subsequent game in the Northern Territory, leading to a decider in Cairns.

The series will feature a decider T20I on August 16, followed by the three ODIs, with the first match scheduled for August 19 in Cairns.

Newcomer Mitch Owen has been ruled out for the series after suffering a concussion from a bouncer delivered by Kagiso Rabada, missing the rest of the T20 series and delaying his ODI debut.

Lance Morris, a young fast bowler with limited international appearances due to injuries and form, has been sent home to investigate his lower back soreness, adding to Australia's injury concerns.

Both Matt Short and Lance Morris have been advised to rest before the upcoming home summer season to recover from their injuries.
