Kimmince made her debut for Queensland aged 17 and her debut for Australia aged 18 against New Zealand in March 2008. The following year, she played in the Women's Cricket World Cup, but she then took a long break from cricket, during which time Kimmince moved to London and worked in the Princess Louise pub in Holborn. During this time, Kimmince was talked into playing for Warwickshire and took a three-hour train journey each way to matches each week without attending training. Kimmince returned to state cricket for the 2012–3 season, and in 2014 returned to playing for Australia, playing in the ICC World T20 tournament in Bangladesh, and in a series against Pakistan at home. In June 2015, Kimmince was named as one of Australia's touring party for the 2015 Women's Ashes in England, as a Twenty20 specialist. However, she was later ruled out due to a lower back issue. In October 2015, Kimmince assumed the captaincy of Queensland Fire, replacing Jodie Fields, who was recovering from shoulder surgery. Soon afterwards, Kimmince became the inaugural captain of Brisbane Heat, but in January 2017, she stepped down from that role and was replaced by Kirby Short. 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 November 2018, she was named in Brisbane Heat's squad for the 2018–19 Women's Big Bash League season. 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. On 4 July 2019, in the second Women's One Day International match of the Women's Ashes, Kimmince took her first five-wicket haul in WODIs. In January 2020, she was named in Australia's squad for the 2020 ICC Women's T20 World Cup in Australia.
