Prior to international competition, Robinson achieved early success in national events, winning gold in women's shot put at the 2012 Australian Little Athletics Championships and captured multiple national junior records such as the under-13 shot put record and the under-11 discus record. By 2013, she held four Australian national records and was ranked the no. 1 Australian junior thrower, after winning gold in both the women's shot put and discus at the 2013 Australian Junior Athletics Championships, setting a shot put meet record of 14.66m. She also notably threw a then-personal best of 16.05m, more than the 15m needed to qualify for the 2013 World Youth Championships in Athletics. She was, however, unable to compete due to age restrictions for the World Youth Championships. In 2014, Robinson was selected as part of the Australian squad sent to the 2014 Summer Youth Olympics in Nanjing, China, to compete in the girls' shot put event. She qualified for the team after narrowly beating Queensland athlete Luisa Sekona during national trials for the Youth Olympics, throwing only 4 cm better than Sekona, at 15.91m. In the qualifying rounds of the girls' shot put event, Robinson threw 15.61m on her third attempt, which saw her place sixth and secure a place in the final. However, she ultimately placed seventh in the final, throwing a distance of 15.42m and failing to capture a medal. Despite the result, Robinson expressed gratitude in an interview after the event, stating, "even though it wasn’t a good throw, I’m pretty happy to be at the Youth Olympics. It’s such a great opportunity." Robinson would later take part in the inaugural 8 × 100 metermixed team relay event the following week, joining four other girls and five boys from various NOCs as part of Team 020 in the event. The team, however, failed to qualify for the final, despite placing third in the third heat of the event, clocking in a time of 1:52.45. Robinson would appear again in international competition at the 2015 Commonwealth Youth Games in Apia, Samoa, competing in the women's shot put alongside fellow Australian athlete Kristina Moore. Robinson threw 16.39m in the event, achieving her goal of beating her previous personal best of 16.25m, and defeating British athlete Sophie Merritt's throw of 15.78m by 61 cm, to claim the gold medal. The win was Robinson's first ever gold medal in an international event, and also set the Commonwealth Youth games record in women's shot put.
Personal life
Robinson was born on 31 December 1998. She was raised with, and trains closely with, her cousin Pita Toamotu, who is also an athlete. Robinson's father Chris raised her and Toamotu as a sibling pair, after Toamotu's father had died early in his childhood. Both Robinson and Toamotu started athletics when they were six years of age, and by age 13, were both training four times a week. Robinson was previously coached by Ray Russell of the St George District Athletic Club, but is now coached by her father, Chris Robinson.
