At the domestic level, Mooney plays as a wicket-keeper/batter for Queensland Fire and the Brisbane Heat. She hopes eventually to succeed Alyssa Healy as the national team's first choice wicket-keeper. In November 2018, Mooney was named in Brisbane Heat's squad for the 2018–19 Women's Big Bash League season. During the final of the WBBL|04 tournament, held on a sweltering Australia Day 2019, she overcame a dizziness-inducing illness to score a player of the match-winning 65 runs from 46 balls. Her innings inspired the Heat to its maiden Women's Big Bash title, with a three-wicket victory over the heavily favoured Sydney Sixers.
International career
Mooney was a member of the victorious Southern Stars squad that won the 2014 ICC World Twenty20 title in Bangladesh. Mooney played her first game for the Australia women's national cricket team in a Twenty20 match against India on 26 January 2016 at the Adelaide Oval. On 26 February 2017, she scored her maiden Women's One Day International hundred against New Zealand. She made her Test debut for Australia Women against England Women on 9 November 2017 in the Women's Ashes. In December 2017, she won both the inaugural ICC T20I Player of the Year and Emerging Player of the Year awards. In April 2018, she was one of the fourteen players to be awarded a national contract for the 2018–19 season by Cricket Australia. In October 2018, she was named in Australia's squad for the 2018 ICC Women's World Twenty20 tournament in the West Indies. In April 2019, Cricket Australia awarded her with a contract ahead of the 2019–20 season. In June 2019, Cricket Australia named her in Australia's team for their tour to England to contest the Women's Ashes. In January 2020, she was named in Australia's squad for the 2020 ICC Women's T20 World Cup in Australia. In Australia's match against Bangladesh, Mooney and Alyssa Healy combined for an opening partnership of 151 runs, the highest partnership for Australia Women for any wicket in a WT20I match. In the final, Mooney top-scored for Australia, finishing unbeaten on 78 off 54 balls to help Australia win their fifth title. Mooney also finished as the tournament's leading runs scorer with 259 runs, including the most fours, and was named player of the tournament.
Playing style
Interviewers have described Mooney as 'flying under the radar', something she prefers to do. However, she admitted in June 2020 that in light of her recent success on the field, keeping a low profile was going to be more difficult. She also said that "... it's all good if I can’t!"
