After initially joining the squad in Brisbane on Monday, Lauren Cheatle has since been ruled out of World Cup contention and returned home to Sydney where she will consult a specialist next week for likely surgery on an ongoing shoulder injury.
The final 15-player squad will be selected following a three-week training camp at the Bupa National Cricket Centre in Brisbane from 24 April – 12 May.

"The ICC Women's Championship showed us how tough this year's tournament is going to be and the players know they're going to have to be at the top of their game to win the title."
