Begins a second season with Alma Pramac Racing to ride a Ducati Desmosedici GP 2019 machine alongside new teammate, 2018 Moto2 champion Pecco Bagnaia.
Jack claims his maiden MotoGP pole position in round two in Argentina, and has front-row starts in Misano (second) and Motegi (third). Takes MotoGP career-best fourth-place results from the races in Argentina and France, and finishes in the top 10 on eight other occasions. Finishes 13th in the world championship with 91 points, his best single-season tally in MotoGP. Signs a one-year extension to stay with Alma Pramac Racing before the Catalunya Grand Prix in round seven.
Jack has his strongest MotoGP season to date, finishing in the top 10 in nine of the 17 races he contested, a broken right tibia ruling him out of the Japanese Grand Prix in October. His comeback from that injury in Australia was dramatic, qualifying a season-best fifth and leading for the opening laps before finishing seventh, while sixth at Assen and Misano were his best race results. Scores 82 points to finish 11th overall.
Jack produces a wet-weather masterclass to take his maiden MotoGP victory at Assen, becoming the first Australian to win in the premier class in nearly four years, and the first independent team rider to win a Grand Prix since Toni Elias in 2006. He also leads in Germany and has five top-10 finishes for the season, but misses five of the 18 races with injuries from various crashes. Finishes 18th in the world championship with 57 points.
Jack became the first Australian to jump directly from the entry-level world championship category to the premier class since Garry McCoy (1998) when he made his MotoGP debut in the Open class for LCR Honda. Finished 19th in the championship with 17 points, including a season-best 11th at Catalunya. Finished as leading Open-class runner in Argentina and Australia. Scored points in six races.

Took six wins, eight poles and 10 podiums in 18 Moto3 races for the Red Bull KTM Ajo team to finish runner-up to Alex Marquez by just two points in the world championship.
