Born and bred in regional Victoria, Jaclyn grew up in Benalla before completing a Bachelor of Laws at Deakin University. After finishing university, she became a disability carer at Alkira Residential Services, where the importance of providing good policy to those who need support became evident. She became an Industrial Officer at the Australian Services Union to further her legal training, before moving into government as an adviser to Deputy Premier and Attorney-General Rob Hulls.
In 2010, she was appointed as Senior Legal and Justice Adviser to then-Opposition Leader Daniel Andrews. In 2014, Jaclyn was elected Member for Northern Victoria, and became the Upper House Government Whip as well as sitting on the Legal and Social Issues Committee, Independent Broad Based Anti-Corruption Committee, Accountability and Oversight Committee and the Legislative Council Privileges Committee. She was incredibly proud to have been appointed to Daniel Andrews 50% female Cabinet following the 2018 election, and even more thrilled to be representing the hardworking farmers, producers and regional Victorians that keep our state moving. She lives with her husband Gerard, their two children and their dog in Sunday Creek, near Broadford.
