The announcement on Tuesday ends one of Australia’s most successful coaching tenures.

“A new era is beginning with the Breakers and the Sydney Thunder and I believe this creates a natural opportunity for me to step away,” Broadbent said.

“I feel I have done as much as I can to develop, challenge and inspire players and staff as the Breakers and Thunder Head Coach.

“This is a decision I have been contemplating for a while and I’m looking forward to some other challenges and opportunities that are on the horizon."

Broadbent took the Breakers to six Women’s National Cricket League (WNCL) titles in the space of seven years, including the last three in a row.

In the past season, she was at the helm when NSW won their 20th domestic 50-over title in the competition’s 23-year history.

She also guided the Thunder to the inaugural Rebel WBBL title in 2016 before coming agonisingly close to another final, falling to the Brisbane Heat in a semi-final.

“I’d like to thank all the players and support staff for their commitment and wish them all the best for the future,” Broadbent said.

Thunder will be searching for a new coach ahead of the first standalone WBBL season this summer.
