Len Ikitau's second-half double was enough for the ACT Brumbies to skip clear after the Melbourne Rebels had fired their first shots ahead of the Super Rugby Pacific season.
The Brumbies led early but needed a second-half surge in a 35-33 win in Wagga Wagga on Saturday.
The Rebels, beaten 24-0 by Fijian Drua in their only other trial game, held sway and led 19-12 early in the second half after stalling the Brumbies' rolling maul and finding space on the left flank.
