The 2019 season saw the return of the trucks to Australia to finish the year, ending a year-long ban on the series by the Confederation of Australian Motor Sport (CAMS).
[20] Continental AG's Continental Tire brand made its SST debut during the weekend, providing the TerrainContact A/T tire for four drivers and fielding a truck for Ryan Beat; two-time SST champion Sheldon Creed, NASCAR veteran Greg Biffle, and sports car driver Ryan Eversley also drove the truck during the season.
[36] On July 27–28, SST competed at Mid-Ohio Sports Car Course for the first time,[37] with Biffle and series veteran Arie Luyendyk Jr. making their first starts of the season.
[43] At Road America, a pair of off-road racers in 14-year-old John Holtger and 19-year-old Christopher Polvoorde made their SST debuts.
[46] Nine drivers, including four with stock car racing experience (Creed, Gordon, Harlien, and Mears), ran the Portland International Raceway weekend with IndyCar.
[48] In late October, SST returned to Australia for the Gold Coast 600 weekend at Surfers Paradise Street Circuit, consummating an agreement formed between the series and the Confederation of Australian Motor Sport (CAMS) to lift the latter's ban on the former in 2018.
