Aged 16, Taryn Gollshewsky first wore the green and gold at the 2009 IAAF World Youth Championships, placing 12th. One year on, she was off to the 2010 IAAF World Junior Championships where she competed in the qualifying rounds. She had thrown a tremendous PB of 53.69m in the lead-up to the championships.
At the Australian Junior Athletics Championships in 2012, she was locked in a four-way tie for the two places in the Australian team for the 2012 IAAF World Junior Championships. Unfortunately, she placed third and missed selection.
Taryn rebounded in 2013 with a PB 54.79m, ahead of a breakthrough 2014 campaign. During the domestic season, she destroyed her PB, with 55.09m in Adelaide, then 56.74m in Brisbane in March, closing the year as the second Australian at the Nationals. Selected for the Glasgow 2014 Commonwealth Games, Taryn nailed a PB of 58.24m in the qualifying round, finishing ninth in the final.
In 2015, Taryn improved her consistency of throws with 53m her lowest throw. But 2016 was another breakthrough season, raising her PB on four occasions reaching 60.27m. Taryn became just the sixth Australian to throw over 60m and only the second for the last 14 years, along with Dani Stevens.
In 2017 her consistency continued with three throws over 59 metres with a best of 59.94m. Although she remained short of the 2017 IAAF World Championships qualifying standard, in late July, she received an IAAF roll down position for London 2017. She was also selected for the 2017 World University Games. In London, she managed 54.29m in the qualifying rounds. On to Taipei for the World Unis later that month, she rebounded with a throw of 58.11m winning the bronze medal.
Seeking selection in her second Commonwealth Games team, Gollshewsky, nailed her season best at the 2018 Australian championships and trials to secure automatic nomination for the team, courtesy of her second placing with a throw of 58.67m.
