At the start of 2012, Murray Stewart stormed into the public eye with a huge run of top performances at the Olympic selection events for the London 2012 Games. The 25-year-old from Sydney came 1st in the K1, K2 and K4 1000m events at the Oceania Championships, before backing up at the Australian Championships to win the same three events and as a result was announced the ICF athlete of the month for March, 2012.
Lining up for three events at the London 2012 Games, undoubtedly Stewart’s highlight of his debut Olympic campaign was taking out gold in the K4 1000m alongside teammates Jacob Clear, David Smith and Tate Smith. In what was a closely fought tussle, the Australians held a 0.09 second lead at the halfway mark of the race before going on to claim victory by 0.61 seconds ahead of Hungary at the Eton Dorney course.
Stewart finish 8th in the B Final of the K1 1000m and 6th in his heat of the K1 200m – missing the semi-finals.
Four years later in Rio, Stewart lined up at his second Olympics. Despite an injury plagued preparation, he was in the mix for a medal in the K1 1000m. In the final he paced himself out of the start with Portugal’s Fernando Pimenta taking the early lead and Stewart in fourth. As the paddlers approached the halfway mark, Stewart made his move and upped his pace to move into second place with London 2012 bronze medallist Josef Dostal of the Czech Republic behind him. But Stewart couldn't hold on as Spain's Marcus Walz stormed to gold and Dostal and Anoshkin claimed the silver and bronze medals, with Stewart just over three-tenths of a second outside the medal places.
