She competed for Australia with teammates Annette Edmondson and Josephine Tomic in the women's team pursuit at the 2012 Summer Olympics. They finished in fourth place after losing to Canada in the bronze final. Hoskins competed at the 2014 Commonwealth Games. At the 2015 UCI Track Cycling World Championships in Saint-Quentin-en-Yvelines, Hoskins was part of the Australian quartet that won gold in the team pursuit, defeating a Great Britain team in the final that had taken the rainbow jersey in the previous four World Championships and that had been undefeated in major competitions during that period. They also broke the world record which had been set by the British in 2013 at altitude in Aguascalientes City by nearly three seconds. She subsequently described this performance as the defining result of her career.
