Jessica Louise Jonassen (born 5 November 1992) is an Australian cricketer from Rockhampton, Queensland. A left-arm orthodox bowling all-rounder, Jonassen has been a member of the national women's team since 2012, going on to win four ICC T20 World Cups while becoming the fourth woman to have taken 100 One Day International wickets for Australia. Domestically, she is the current captain of both the Queensland Fire in the Women's National Cricket League (WNCL) and the Brisbane Heat in the Women's Big Bash League (WBBL). Early life and education Jonassen was born in Emerald, a rural town in the Central Highlands Region of Queensland, but grew up approximately away in the coastal city of Rockhampton. She attended high school at Emmaus College, Rockhampton, graduating in 2009. When Jonassen was 10 or 11, she started playing cricket, initially at school and later for Rockhampton Brothers. She played in boys' teams; at that time, there were no girls only cricket programs in rural Queensland. Jonassen progressed through third grade and second grade levels, and eventually played a couple of A-grade games not long before she finished school and moved to Brisbane. There, she played for University of Queensland. After completing a law degree at Griffith University in 2015, Jonassen continued her studies by undertaking a graduate certificate in forensic mental health.

During the 2010–11 season, Jonassen took her batting to a new level, scoring the fifth-most runs in the league with 228 at an average of 57 and earning Queensland's Player of the Year award. She won the same award again, as well as the league-wide Player of the Year title, for the 2014–15 season in which she took the second-most wickets (eleven at an average of 13.36) and scored 197 runs at 49.25 despite missing several games due to injury.
