Australia 'centurions' Stephen Moore and Matt Giteau focused on Scotland

Australia captain Stephen Moore and centre Matt Giteau are set to win their 100th caps in the Rugby World Cup quarter-final against Scotland at Twickenham on Sunday.

However, personal milestones are not a concern for the duo as the Wallabies attempt to book their place in the last four after topping Pool A with four successive victories.

"For me, it's not really a week to be reflecting on things," said 32-year-old Moore.

"We've got a great opportunity to play in the quarter-final of a World Cup and that's more than enough to play for. These personal achievements are things you probably look at when you hang up your boots."

Giteau, 33, made his debut against England at Twickenham in 2002.

"We lost by a point," he said. "I think I went on with about eight minutes to go.

"[Coach] Eddie Jones had a score system where you got a point for every positive thing you did and lost a point for every negative. I think I was the only player to finish with a minus. After that game, I never thought I'd get to a hundred [caps]. I didn't think I'd get past one."

The Wallabies are warm favourites to win but remain wary of the threat posed by Scotland, who finished as Pool B runners-up by winning three of their four games.

"Their set-piece game looks very strong. They've got a great goalkicker and captain who leads them around really well," Giteau said.

"They look like a very confident team who know what they want and know the style of rugby they want to play, and they've been executing it very well."

Back-row forward David Pocock will be available to face Scotland after avoiding a citing and flanker Michael Hooper returns after suspension ruled him out for the win over Wales.

"It's good to have everyone on deck," Moore said. "We've already lost a couple of important players to injury. Every team goes through that and it's a challenge of a World Cup.

"It's good that Dave's all good for the weekend, he's an important player for us."
