Larkyn Austman was born February 22, 1998, in New Westminster, British Columbia, Canada. Her parents, Heather and Leonard, both competed in figure skating, and her older brother, Connor, played ice hockey. Her mother, formerly Heather Anderson, won the Canadian national novice ladies' title in 1974. Austman attended Hillcrest Middle School and Dr. Charles Best Secondary School in Coquitlam, graduating in June 2016. She became a vegan in June 2015.
In 2013, due to boot problems, Austman developed tendinitis in both of her Achilles tendons, causing her to miss part of the 2013–2014 season. In October, she debuted on the ISU Junior Grand Prix series, finishing eighth in Tallinn, Estonia. In January, making her senior debut, she placed tenth at the 2014 Canadian Championships. In March, Austman competed at the 2014 World Junior Championships in Sofia, Bulgaria. Ranked eighteenth in the short program, she qualified to the free skate and finished sixteenth overall. She was coached by Heather Austman and Eileen Murphy in Richmond and Coquitlam, British Columbia.
2014–2015 and 2015–2016 seasons
In 2014, Austman spent three months training in Colorado Springs, Colorado under Christy Krall. In August, she placed tenth at her 2014 Junior Grand Prix assignment in France. She quit skating in December but started to reconsider in March 2015. Austman rejoined Coquitlam Skating Club and resumed training, skating at the Poirier Sport and Leisure Complex. She finished sixth at the 2016 Canadian Championships.
In addition to training in British Columbia, Austman trained in Edmonton during the summer and in Colorado Springs, Colorado for five weeks during the winter. She crowdfunded to cover her expenses and received financial aid of $30,000 from Horatio Kemeny. In January, Austman won the bronze medal at the 2018 Canadian Championships. The following day, she was named in Canada's 2018 Olympic and 2018 World teams. In February, she competed at the 2018 Winter Olympics in PyeongChang, South Korea. Ranked twenty-fifth in the short program, she missed qualifying for the final segment by one spot. She had the same result at the 2018 World Championships in Milan, Italy.
2018–2019 season
Austman sprained her left foot in September 2018, causing her to withdraw from the 2018 Skate Canada International. At the 2019 Canadian Championships, Austman returned to competition, and placed second in the short program, skating cleanly. She stated that her result there validated her decision to withdraw from the Grand Prix, which would otherwise have worsened her physical health and confidence. She was less successful in the free skate, dropping to fourth place overall. Austman was assigned to compete at the 2019 Four Continents Championships, as silver medalist Aurora Cotop lacked the technical minimum scores necessary to attend. She finished tenth at Four Continents, setting personal bests in the process, but failed to obtain the short program technical minimum score necessary to be eligible to attend the World Championships, missing it by 0.01 points. On May 10, Austman announced her retirement from competitive skating through a post on Instagram.
