An outstanding performance from flanker George Smith led the Brumbies to a dominant 30-19 win over the Highlanders after his backs launched a relentless aerial assault on their winless Super Rugby foes in Dunedin.

While Smith wasn't listed in the Brumbies 30-man Wallabies camp earlier on Friday, coach Robbie Deans surely must be flirting with the thought of bringing the 110-Test veteran back into the national side.

Smith's highlights included forcing a turnover that led to an early penalty goal and scoring a try off the back of a disintegrated rolling maul in the 31st minute.

Brumbies coach Jake White was singing the 32-year-old comeback king's praises.

"He was outstanding. I don't like to single guys out - it's not my style - but, when you see a performance like that, it just highlights how good he actually is," White said.

"He's getting better and better every week."

The Brumbies continued their recent trend of blitzing sides early, opening the scoring in the third minute when winger Henry Speight brushed off his opposite Hosea Gear, stepped inside fullback Ben Smith and then carried Ma'a Nonu over the line.

"To get a performance like that from Henry, I'm sure he's going to take an enormous amount of confidence from that," White said.

However, the blistering start was overshadowed by an injury to Brumbies outside centre Andrew Smith.

Fullback Jesse Mogg and halfback Nic White created havoc for the Highlanders all night with midfield bombs followed up by a strong chase.

"They've got such a great back three with Hosea Gear, Ben Smith and Kade Poki, we knew that if we were going to kick, we'd kick properly and make sure we put them under pressure," White said.

"Everything was on song. Defensively, we took another step up."

The high ball tactic paid dividends in the 31st minute when the Highlanders failed to clean up a Mogg rainmaker and the Brumbies were rewarded with the five-metre lineout from which Smith scored.

The Highlanders kept in touch throughout the first half courtesy of four penalty goals to debutant five-eighth Hayden Parker to limit the damage to 17-12 at the break.

After two Brumbies penalty goals straight after halftime, winger Joe Tomane swooped on one of the many Highlanders' knock-ons and ran 55 metres to score to give the ACT franchise a 30-12 lead in the 54th minute.

Halfback Aaron Smith came off the bench in the second half to slip across for a try late in the match for the home team but it was too little, too late.

The Highlanders have became the first New Zealand side to lose 10 successive Super Rugby matches and will be sweating on the fitness of Poki, who limped off at halftime with the recurrence of a rib injury.

The Brumbies, on the other hand, will either consolidate themselves as the frontrunner of the Australian conference or lead the Super Rugby table depending on the outcome of Saturday's Chiefs v Reds match in Hamilton.
