After winning the Australian novice title for two consecutive seasons, Harris made her international competitive debut in the 2016–17 season, beginning on the Junior Grand Prix, where she placed eleventh at the JGP Germany. Next winning the Australian junior national title, she was assigned to compete at the 2017 World Junior Championships, where she qualified for the free skate and placed twenty-third overall. She described it as "an amazing experience" and anticipated training for the following season, but it would be her last international competition as a singles skater.[1][3]
Harris afterwards suffered multiple concussions that she described as making her "a little bit afraid to hit my head again." She opted instead to switch to ice dance.[4]

After the Grand Prix, Harris/Chan won gold at the Santa Claus Cup and came seventh at the 2022 CS Golden Spin of Zagreb.[8]
