The following season, Team Jackson was invited to play in the third leg of the 2018–19 Curling World Cup, finishing with a 2-4 record. Two weeks later, the team won the 2019 Scottish championship, defeating perennial winners Eve Muirhead in the final. Team Jackson had committed to play in the 2019 Winter Universiade (which ended just before the World Championships), so Scottish Curling initially wanted to send Muirhead to the 2019 World Women's Curling Championship as Scotland's representative. However, Team Jackson asked for a review of the rules, which stated the winner of the Scottish championship gets to represent the country at the World Championships. The review was successful, and Team Jackson went on to represent Scotland at the 2019 Worlds. They also played in the Universiade, where they finished fourth.
