Samu locked in with Wallabies, Brumbies

Gun Wallabies back-rower Pete Samu has added an extra year to his Brumbies and Rugby Australia contract ahead of his side's match against Fijian Drua on Saturday afternoon.

A veteran of 19 Tests, Samu is now locked in through 2023, meaning he's positioned to be a key part of Australia's World Cup tilt next year.

The 30-year-old said there was minimal temptation to leave the nation's capital.

"Me and my family are really settled here, and the opportunity to stay another year - I didn't think twice," he told reporters.

"I'm stoked and grateful for the opportunity to stay another year. This club means a lot to me and my family."

Wallabies coach Dave Rennie said he was thrilled the Samu deal was inked.

"His athleticism and speed are a point of difference across the backrow and we think his best footy lies ahead of him in the gold jersey," he said.

It comes as the Brumbies approach their Super Rugby Pacific round-two clash against Fijian Drua knowing they need to improve on their first-round effort.

They struggled at the lineout, turned the ball over 19 times, spent almost the entire first half in defence and needed a miracle last-minute try to wrestle a 29-23 win against the Western Force, and captain Allan Alaalatoa stressed the importance of a better showing in round two.

"There were a lot of learnings from last week ... we made too many mistakes and what we do know is if we do the same thing tomorrow they'll probably capitalise on that.

"We need to improve a lot of areas ... in defence and then mistakes.

"We turned over the ball too many times, that's gonna happen but if it does we need to be better at reacting and moving onto the next job."

The Fijians showed glimpses against the Waratahs in round one but eventually
