In May 2018, the series formed an alliance with Boost Mobile to increase its presence in Australia. As part of the agreement, Paul Morris Motorsport became a logistics partner for the series' Australian operations. However, SST was banned by the Confederation of Australian Motor Sport (CAMS) later that month for safety reasons. When the trucks returned in 2019 under the Boost Mobile Super Trucks name, Paul Morris Motorsport's Norwell Motorplex became its headquarters. In October 2019, Morris also ran his first SST race of the year at Gold Coast; he led much of the second race before colliding with Cole Potts on the final lap, surrendering the win to Brabham.
