MXGP race one in Mattreley Basin started with a holeshot from Red Bull KTM Factory Racing’s Antonio Cairoli just ahead of his teammate Glenn Coldenhoff. A few spots further back was the other Red Bull KTM of Jeffrey Herlings, the 2018 MXGP points leader. A bad lap and some mistakes left Herlings in a position to take the lead, but Cairoli fought back and the two carried on for the next laps. With two laps to go Herlings dove to the inside of Cairoli. Herlings kept on the gas with Cairoli trying to cut in and they both came together with Cairoli going down. Herlings took the race win, but Cairoli got up quickly and managed second with Tim Gajser 3rd.
