Autralian internationals Holly Ferling and Julie Hunter face time on the sidelines with lower back and thumb injuries respectively.
Ferling has a stress fracture with bone stress reaction in her lower back and will soon undergo surgery while Hunter has had an operation to repair a fractured thumb.
While Hunter is expected to be fit for Australia's series against Pakistan later this year, Ferling is not expected to recover in time.
"Holly had scans following her return to Australia after the ICC Women’s World Twenty20 in Bangladesh," Cricket Australia (CA) Chief Medical Officer Justin Paoloni said.
"She has experienced ongoing lower back pain and her age, developing bones and the fact that she’s a fast bowler are all contributing factors.
"Holly is currently undergoing extensive rehabilitation and will not be available for selection for the series against Pakistan in late August. We are gearing her rehabilitation towards being available for selection later this year."
Commenting on Hunter, Dr Paoloni added: "Julie suffered a knock to her left thumb during the ICC Women’s World Twenty20 in Bangladesh.
"Since returning to Australia, an x-ray revealed that she had sustained a fracture in her left thumb which required surgery.
"Julie is currently undergoing rehabilitation and is expected to be available for selection for the series against Pakistan."
Australia take on Pakistan in August.
