Brumbies coach Dan McKellar says "nothing changes" with the Brumbies going top of the Australian Super Rugby conference with a 33-0 win against the Sunwolves in Canberra.

Sunday afternoon's five-try victory made it five straight for the Brumbies at home as they overtook the Melbourne Rebels to lead the four Australian teams with five rounds remaining.

Having taken offence at perceived criticism for dull, set-piece oriented play, the Brumbies cut loose.

They scored three tries inside 30 minutes as giant centre Tevita Kuridrani ran riot and boosted his Wallabies recall chances.

"That was nice, some of our turnovers sparked Tevita and (winger) Henry (Speight) into some space and the pressure our forwards applied up front was good," Brumbies captain Christian Lealiifano said.

"We knew how unpredictable they were going to be and they're a really good attacking side so that's impressive keeping them to zero.

"It doesn't matter if it's the first minute or the last minute. It impressed me to see it in guys' eyes to want to defend and play big and do all those little things you can easily brush over."

McKellar echoed the sentiment saying he was proud to see his men dig deep with some tough goalline defence in the final minutes.

"I thought our effort all night was very good. Then in the last 10 minutes in defence there, a lot of teams would be happy to concede and you still get a good win," McKellar said.

"It's pleasing (to go top) but nothing changes - we're not too obsessed with the ladder. You just keep accumulating points and winning footy games; the outcome will look after itself."

The Sunwolves crossed first when Gerhard van den Heever dived over in the corner but it was called back when the TMO found the winger had put a foot in touch.

After a slow opening 15 minutes, the Brumbies scored when Speight and Kuridrani combined for an 80-metre try that the former finished between the posts.

They made it two in two minutes when Kuridrani again burst off his own line and ran 60 metres before Joe Powell finished the length-of-the-field try.

The Sunwolves stopped consecutive mauls from five metres out but the Brumbies shifted it wide and Speight scored the third on 27 minutes.

In the second half, the Brumbies picked up where they left off, scoring a sensational set-piece try on 52 minutes.

Inside centre Irae Simone threw a perfectly weighted pass to Speight who pierced through the middle and put fullback Tom Banks into the corner.

Banks made a try-saving tackle before Kuridrani broke the line again and found No.8 Pete Samu, who ran 40 metres to score the fifth try.
