Morrison was first selected to represent Victoria in the 2016 senior women's eight which won the Queen's Cup at the Interstate Regatta within the Australian Rowing Championships.

[9] Morrison was in the Australian women's eight which initially missed qualification for the 2016 Rio Olympics but received a late call up following the Russian drug scandal.

With Annabelle McIntyre she was selected to race the coxless pair and they took a silver medal at Rowing World Cup II in Poznan and won the gold in that event at RWC III in Rotterdam.

[11] Two days rowing at the Olympic regatta were lost due to bad weather and in the reshuffled schedule Morrison and McIntyre's semi-final in the pair started less than two hours after the medal ceremony for the four.

[11] At the Henley Royal Regatta in 2022 Morrison teamed up with American Meghan Musnicki and went through to win the final of the Hambleden Pairs Challenge Cup over the British crew racing as Leander.

[11] They backed up that performance three weeks later at the WRC III in Lucerne, winning their heat and semi-final and comfortably taking gold in the W2- final.

[11] Morrison and McIntyre contested the Australian women's pair at the 2023 World Rowing Championships in Belgrade, Serbia where they won their heat and semi-final at which point they qualified the boat for the 2024 Paris Olympics.
