The Brumbies have stamped themselves as Super Rugby title contenders, bursting out of the blocks and smashing the Sharks 29-10 in Durban to remain the only undefeated side in the competition.

The Brumbies are now six points clear of the second-placed Chiefs on the Super Rugby ladder, having won all four games this year.

The win was also their seventh in a row on the road, giving them the record for the most consecutive away wins in Super Rugby history.

Coach Jake White's team ran onto Kings Park Stadium like a team possessed, launching wave after wave in attack to tire out last year's Super Rugby runners-up and rack up the four try bonus point in just 34 minutes.

But it wasn't just with ball in hand that the Brumbies pushed forward, with their rush defence putting the Sharks on the backfoot throughout the match and openside flanker George Smith creating absolute havoc at the breakdown.

Man-of-the-match No.8 Fotu Auelua was extremely dominant in the first half, his direct running sucking in three defenders in the build up to the first two tries to create overlaps on both occasions.

"Fotu led from the front and worked hard to get us over the advantage line," White said.

"It's fantastic and rewarding for a coach when you make a couple of changes and get a return from the boys who get a chance."

Fly-half Matt Toomua and Christian Lealiifano both had outstanding games, with former Sevens player Tevita Kuridrani providing additional flair in his first start to of the season at outside centre.

"One thing I enjoy about Matt Toomua is his ability to take the ball to the line and keep defenders honest to create space out wide," White said.

Halfback Nic White suffered a head knock in the first tackle of the match and was soon replaced by Ian Prior, who was sensational in directing the flow of the play and providing runners with wide, flat passes.

Standout fullback Jesse Mogg was another injury concern, coming off with an injured left shoulder in the 57th minute.

The Brumbies started in the best possible way, patiently working the ball up the field and not making a single error before Mogg went over in the fifth minute.

They continued their expansive, error free rugby to send Joe Tomane over in the corner to lead by 12 points in as many minutes.

A tackle fatigued sharks forward pack then lost a centre-field tighthead scrum in the 34th minute, with Toomua catching the blindside defence off guard and throwing a looping cut out pass to Henry Speight to bring up the four-try bonus point.

Heavy rain fell at half time, stifling the Brumbies expansive game plan.

The Sharks also improved on their first half performance, with captain Keegan Daniel leading the way with the only try of the second half in the 51st minute.

Daniel said the Brumbies were successful at holding onto the ball for long periods of time, sucking in their defence and then spreading it wide.

"Offloads hurt you in rugby and they managed to do that a lot in the first half," he said.
