THhe ACT Brumbies lead fellow 2013 grand finalists the Waikato Chiefs 13-6 at Canberra Stadium.
Brumbies half Matt Toomua scored the only try in the half that featured four penalty goals.
Last years premiers the Chiefs held early momentum, but Toomua's try swung the round 12 fixture towards the home side.
The game started with an unofficial anthem performance by Brumbies supporter group the rUCkus crew, while Australia's four living Victoria Cross holders were also present.
A tough second half is on the way, with the game still anyone's to take.
