Brumbies assistant coach Stephen Larkham has told his players that they need to need increase their intensity and put their bodies on the line and that they need a do-or-die mentality this week.
The Brumbies legend has been through Super Rugby finals four times and won two Super Rugby titles as a player.
"It's do or die," Larkham told AAP.
"You get that intensity for the full 80 minutes, particularly the contact areas.
"Guys will throw themselves in there a little bit more.
"They're not going to hold anything back because they're not worried about injuries as it's potentially the last game of the season."
The Brumbies will have home advantage over the Cheetahs in this week's Super Rugby qualifying final but they will be going into the their first play off in nine years off a loss and before that a one month break.
Larkham says that he is confident that they can bounce back quickly and uses France in the 2011 Rugby World Cup as an example as they lost to Tonga in the Pool stages but went on to reach the final.
The Brumbies lost 21-15 to the Western Force in Perth last weekend in their final regular season match.
"You look at the French in the World Cup. They got through to the final and nearly beat New Zealand, having played so poorly in the round games," Larkham said.
"Your form beforehand doesn't really matter."
"You can change your mindset in a week quite easily in Super Rugby."
Wallabies and Brumbies inside centre Christian Lealiifano said that the feeling in the Brumbies camp was better this week and that he could feel things starting to click again at training.
"Absolutely, it's about our time together, training together and then everything should happen on Sunday," Lealiifano said.
"You've just got to build to that each day and the boys are definitely doing that.
"This group definitely bounces back from a loss."
