Qualifying 11th for Melbourne, he earned his breakthrough in the sprint having started second. After a hard-fought battle with Laurens van Hoepen for the lead, he succeeded in the battle and emerged for his first F3 victory of the season.

He returned to the points in Barcelona with fourth place during the sprint, but was unlucky to suffer a puncture on the last lap from battling Van Hoepen for seventh.
Starting on reverse pole for the sprint race in Austria, he dropped to third on the opening lap, but an error from Christian Mansell towards the end of the race lifted Stenshorne to second place.

He finished eighth in a wet feature race. Starting second in the Bahrain sprint race, Stenshorne struggled with race pace throughout the weekend and he fell to fifth place, whilst he dropped out of the points from 11th in the feature race. Having failed to score in Imola, Stenshorne took his first win of the season in the Monaco sprint race, having passed Alessandro Giusti for the lead off the start line in which he held from start to finish. He made up three places in the feature race and finished in eighth place. Stenshorne was in prime position once again to fight for the win in the Barcelona sprint race starting second, but a collision with Tim Tramnitz and Roman Bilinski sent him into the gravel and out of the race. He had a superb start in the feature race and improved to fifth, but a drop in pace in the second half of the race meant he finished down in ninth place.
Stenshorne qualified down in 15th in Spielberg, but he fought his way through the field in the sprint race, and despite being passed by Mari Boya on the final lap, he still managed to finish in seventh. He replicated his comeback in the feature race, this time being even more impressive as he charged forward to second place, but was promoted to the victory after Nikola Tsolov was disqualified due to a technical irregularity. He qualified seventh in Silverstone, earning back-to-back rostrums after overtaking his rivals to finish runner-up in the sprint race. In the feature race however, his run of form was halted with a wrong choice of dry tyres on a wet track, leaving him to finish down in 17th place. He had his best qualifying of the season in fifth in Spa-Francorchamps. He took points with seventh place in he sprint race, but treacherous weather in the feature race saw it cancelled, depriving Stenshorne the opportunity to add to his tally. A poor qualifying in Budapest left him down in 20th, and he ultimately failed to score points, even attempting to fit slick tyres during a drying track in the feature. In the Monza finale, Stenshorne returned to the podium with a runner-up finish after battling Tramnitz and Bilinski for the top positions. In the feature race, he ran as high as fifth but picked up a puncture after contact with Matías Zagazeta, necessiting him to pit.
