Brumbies captain Matt Giteau says his side won't be drawing any extra motivation from the chance to spoil the Waratahs' hopes for the finals in their Super Rugby clash on Saturday.

The Brumbies are solely focused on using their last match of the season to build momentum for 2012.

And Giteau said a win in his final match for the Brumbies was about his side, not crushing the seventh-placed Waratahs' hopes of qualifying for the six-team finals series.

"I don't really like that spoiler tag," he said.

"It is a bit of a negative tag, but for us we just want to build on the last two weeks and hopefully get three wins against Australian teams back-to-back."

The Brumbies have posted wins in their past two matches over leaders Queensland Reds and the Melbourne Rebels and will be keen to continue their season-best form against NSW in Sydney.

A victory would also avenge the 29-22 home loss to the Waratahs in March.

"Obviously we want to finish on a high, while the Waratahs have a lot to play for," Giteau said.

"Although we don't have any semi-final spots to play for, there is a lot of pride within the group and hopefully we can show them that this weekend."

The Test back will head to France after the 2011 Rugby World Cup and is one of a host of players leaving the Brumbies following Saturday's match.

But coach Tony Rea said football, and not emotions linked with the departing players, was the focus this week.

"We have spoken a lot about strategy and game plan," Rea said.

"We haven't been really doing the `it is the last game and it is our last time together'."

Giteau said his side had to contest a strength of the Waratahs, the breakdown, this weekend.

"In attack, they hit and contest at the breakdown really well," he said.

"When they've got the ball at the breakdown, defensively we've got to be able to mark across the whole field."

Rea has picked backrower Ita Vaea, back from suspension, to strengthen his backrow against NSW.

It follows 22-year-old Vaea's one-match ban for a high shot on Digby Ioane in the Brumbies' shock win over the Reds in Brisbane.

Vaea slots back at No.8 with Mitchell Chapman switching to blindside breakaway and Henry Vanderglas dropping to the bench.

Scrum-half Josh Valentine returns from a hamstring injury to a spot on the bench while lock Sam Carter and scrum-half Nic White drop out of the match-day squad.

The match will also be Rea's last at the Brumbies.

He became head coach following the sacking of Andy Friend after round two.

"Hopefully we send him (Rea) out on a high this weekend," Giteau said.

South Africa Rugby World Cup winning coach Jake White will become coach of the Brumbies from July.
