Alyssa Healy progressed rapidly through representative ranks in New South Wales before making her debut for the Lendlease Breakers in the 2007-08 season.
She was forced to shelve her wicketkeeping gloves for much of her first two seasons, allowing her to develop her top-order batting skills.
Healy settled in behind the stumps at the beginning of the 2009-10 domestic season, which proved to be a breakout season for her, recording her highest score of 89 not out and leading the WNCL in dismissals.
Healy was called into the national side for the 2010 Rose Bowl Series against New Zealand at the age of 19. A few months later she played every match in the ICC Women’s World Twenty20 in the West Indies and helped Australia take home the title.
On the 2012 tour of India, Healy posted some of her best international performances in green and gold, including a career-best 90 in a T20 at Vizag.
Healy tasted more success with Australia later that year as part of a second-straight ICC Women’s World Twenty20 champion side in Sri Lanka. She was also a part of the team that hoisted the ICC Women’s World Cup trophy in India in 2013 and another third World T20 victory in Bangladesh in 2014.
Her WBBL career unfurled soon after she helped Australia win back the Ashes from England in 2015, signing with the Sydney Sixers for the inaugural edition.
In 2018, Healy was named ICC T20 player of the year after her outstanding performances that drove her nation to a fourth ICC World T20 title.
In 2020, Healy was Player of the Match in Australia's T20 World Cup Final victory over India at the MCG.
