Both teams boasted 100 percent records heading into the match but it was the ACT side that took the initiative against their South African opponents from the first whistle.
In an impressive first half, the Brumbies took a firm grip, scoring four unanswered tries to grab a deserved bonus point.
The Australian visitors enjoyed 75 percent possession and territory in the first 40 minutes and made the home side pay to lead 26-3 at half-time with Jesse Mogg, Joe Tomane, Matt Toomua and Henry Speight scoring tries and Christian Lealiifano landing three conversions.
The Sharks were restricted to a single penalty from Pat Lambie in the opening 18 minutes.Things improved slightly for the home side after the break.
Trapped in their own 22, the Sharks did exceptionally well to work their way into the opposition half.
Ryan Kankowski finished off a big build-up to score a try in the 52nd minute which Lambie converted to give them some confidence but it was too little, too late.
It was the first time the Brumbies had conceded any points in a second half this year, and only the second try to be scored against them so far.
Brumbies captain Ben Mowen was understandably delighted.
"We're extremely happy. Kings Park is not an easy place to come and win," Mowen said.
"We know that against the Sharks you have to be really physical and I was happy with our effort."
