The Brumbies kept the Force scoreless in their 25-0 victory in Darwin on Saturday.
Jake White’s side scored two early tries through lock Ben Hand and inside centre Christian Lealiifano, while flyhalf Zack Holmes nailed three penalties to establish a formidable first-half lead.
The wet and windy conditions affected the handling on both sides, but the Brumbies’ defence also impressed by keeping the Force at bay.
Utility forward Peter Kimlin was yellow carded in the second half, but the Brumbies maintained a high defensive standard to deny the Force any reward. Nic White kicked two penalties to complete the convincing win.
