Heather Graham will replace the 20-year-old, who had been selected as a reserve for the tournament in New Zealand
Australia will be without Hannah Darlington for the upcoming Women's World Cup after she withdrew from the tournament to protect her mental health and wellbeing.
The 20-year-old, who has played two one-day internationals and a pair of T20Is for her country, had been selected as a reserve for the tournament in New Zealand.
She will be replaced by Heather Graham, with Georgia Redmayne the other named reserve.

All players will be forced to undergo 10 days of quarantine upon arriving in New Zealand before the World Cup gets underway on March 4.
Darlington has enjoyed a fine 2021/22 season, making her first international appearances in the multi-format series against India in September and October.
In the absence of Rachael Haynes, she captained Sydney Thunder in the Women's Big Bash League, taking 16 wickets at 20.75.
It was an otherwise disappointing campaign for Thunder, who finished one off the bottom in the regular season.
