Wallaby lock Scott Fardy admitted that the 24-10 victory over the Force on the weekend did not feature the best the Brumbies had to offer.
Australia's most successful Super Rugby franchise laboured to a three tries to one win over the lowly Force at GIO Stadium on Saturday.
A slow start saw the first points scored in the 21st minute and while Canberra-based outfit dominated the rest of the half, both teams went scoreless in the second stanza.
"It was a bit of a strange game on Saturday," the 32-year-old told the Brumbies website.
"I'm the first to admit I didn't play at my best and we didn't play at our best, but finals are a different story.
"Coming into that game we knew we only had to get one point. It was hard to get going."
Meanwhile, Fardy is hoping the Brumbies faithful come out in full force when they take on the Highlanders in their quarter-final on Friday.
The Brumbies played in front of just over 9,000 people on the weekend and Fardy indicated that while the team is motivated ahead of Friday's clash, a bigger crowd would certainly motivate them further.
"We're very excited, it's the fourth time in a row that we get to play in the finals and we're looking forward to what should be a good few weeks," he added.
"But first and foremost we're looking forward to Friday night and getting a big crowd at GIO Stadium.
"It's huge for us. Every time you get a big crowd you can see the result and the players lift.
"It's huge for us to have a big crowd in and it's great for the game in the capital and we're looking forward to it."
The chilly Canberra weather has certainly played a part in the smaller crowds and with a low of three degrees and a chance of rain on Friday, organisers have pulled all the stops to pull the crowds. An earlier kick-off and meat pies to the first 2,000 spectators are just some of the strategies in place.
"18:00 is warmer than a quarter to eight," quipped Fardy.
"I think fans should knock off early, have a few drinks on your way there and you should be able to go out to dinner after the game as well.
"It's a one off thing that we kick off at 6:00pm and a good opportunity for Canberra to have a look at what we do and possibly send off a few guys that have played a lot of games for the Brumbies."
