The Melbourne Rebels have registered their first Super Rugby win in Canberra, beating a decimated Brumbies 13-8 on Saturday night.

Despite the rain and hostile 7,531 fans, the Rebels dominated proceedings at GIO Stadium for their second away victory this season.

For the Brumbies, the loss was their third in four matches.

While they remain Australian conference leaders, the NSW Waratahs are hot on their tails after their bonus-point victory over the ladder-leading Hurricanes in Wellington earlier in the day.

With injuries forcing more than a dozen changes to their line-up, the Brumbies struggled against an organised Rebels outfit.

The visitors played to the wet weather, keeping the hosts pinned in their own half and being resolute in defence.

They were first to get on the board, with Matt Harris scraping home a penalty goal almost 10 minutes in.

Their 3-0 lead blew out to 10-0 moments later after Nick Stirzaker sliced through from a scrum and got a wide ball out to Sefanaia Naivalu who crossed.

It ended an impressive streak for the Brumbies, who had scored the first try in all previous nine matches between the two sides.

The momentum continued Melbourne’s way, the visitors awarded seven penalties to two in the opening half; the Brumbies had to wait nearly 32 minutes for their first.

The Rebels were headed towards their second-ever first-half cleansheet in five seasons, until Henry Speight spoiled it after the siren.

The outside centre dived over in the corner for his first five-pointer in 2015 on the back of some quick hands to head into the break 13-5 down after Christian Lealiifano’s conversion was slapped down.

Lealiifano went on to add three points via a 63rd-minute penalty goal to reduce the deficit to 13-8, which remained unchanged.

To add to the Brumbies’ injury woes, a bloody-nosed Lausil Taliauli was taken off with apparent concussion 30 minutes into his first Super Rugby start and replaced by debutant Rodney Iona.
