Matt Giteau led the Brumbies to a 32-17 bonus point victory over the Rebels in his final match in Canberra for the ACT Super Rugby franchise.
Giteau has agreed to join Toulon after the world cup and will play his final game for the Brumbies against the Waratahs in Sydney next week.
The match was also the last home game for Adam Ashley-Cooper who will join the Waratahs next year making his trip to Sydney next week a special one.
The victory was the Brumbies second in a row and their first successive victory of the season and was payback for their 25-24 loss to the Rebels in Round 2.
The Brumbies outscored the Rebels by five tries to two and Matt Giteau scored one and created another.
The two-time champion Brumbies cruised to a 25-3 lead shortly after halftime but the Rebels, with wayward English international Danny Capriani making his first appearance since April after his disciplinary issues, hit back to trail 25-17 with eight minutes left.
"It's nice for the group to build momentum and something to be proud of going into the backend of the season," Giteau said.
"With attitude you get better defence and the boys have worked harder and we took it into this game, although we took our foot off the pedal a little bit, but we regrouped and scored another try."
The Brumbies clinched victory with a try by Wallabies' hooker Stephen Moore off a rolling maul minutes later.
The Brumbies' other tries were scored by Christian Lealiifano, Tyrone Smith, Giteau and Pat McCabe with Giteau landing two conversions and a penalty goal.
The Rebels, who slumped to their 12th loss in their debut season, scored tries through Jarrod Saffy and Afusipa Taumoepeau with Cipriani landing two conversions and a penalty goal.
The loss ensured that the Rebels will finish last in the Australian Conference, while the bonus point moved the Brumbies ahead of Western Force in the conference.
It was a bitter-sweet return to the ground where Rebels' skipper Stirling Mortlock played 13 seasons before switching to Melbourne this season.
"Late in the second half we started to get better shape and cohesion in attack, but it's very disappointing when we don't hold on to possession," Mortlock said.
"It's very nice to come back with a lot of memories and mates here, but it was disappointing that the Rebels weren't able to get one up tonight."
The Brumbies finish their season against the playoff-chasing the Waratahs in Sydney next week, with the Rebels having home advantage against the Force.
