Her state representative debut for Western Australia came in the 2014 youth eight which contested the Bicentennial Cup at the Interstate Regatta within the Australian Rowing Championships.

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

[11] She was again selected in the Australian women's eight and also with Morrison to race Australia's coxless pair at the 2019 World Rowing Championships in Linz, Austria.

[11] In the Australian women's eight they placed second in their heat, came through the repechage and led in the final from the start and at all three 500m marks till they were overrun by New Zealand by 2.7secs.

[11] Four days later in the final of the coxless four they led from the start, were challenged hard to the finish by the Dutch crew but took the gold in another Olympic best time.

[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.

The girls were challenged in the semi and although they finished less a second behind the winning Greek pair, they were in fourth place and missed the cut of the A final.

[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] McIntyre and Morrison 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.
