Hailing from Bendigo in central Victoria, Kerryn grew up playing Basketball at an elite level from early age. At the tender age of 15, after already making her debut in the WNBL with the Bendigo Spirit, Kerryn moved to Canberra to take up a scholarship at the Australian Institute of Sport. She went on to represent the Under 19 Australian team at two World Championships in 2009 and 2011, the latter as Captain. Kerryn played over 150 games in the WNBL playing for Bulleen Boomers, Adelaide Lightning and the Bendigo Spirit.
With the success of the AFLW in its inaugural season, Kerryn made the difficult decision to leave basketball behind and pursue a career in the AFLW. Kerryn was initially signed as a cross-code rookie by the Carlton Football Club before being elevated to its senior list in 2017. She made her debut in Round 1 against archrival Collingwood in 2018. She has since been named as a dual All-Australian defender (2019 & 2020), twice finishing 3rd in the clubs best and fairest (2019 & 2021) and was announced as Co-Captain before the 2020 season.
In 2017, Kerryn graduated from La Trobe University with a Bachelor of Exercise Science and Masters in Physiotherapy Practice. She has previously worked with the Carlton men’s AFL team as a physiotherapist whilst training for AFLW and continues to work part time in a private hospital in Melbourne. Kerryn also has an interest in sports media and has worked with ABC grandstand as an AFLW expert commentator.
