Brumbies boss Jake White has named an unchanged matchday 22 for Saturday's semi-final against the Bulls in Pretoria.
It's been nine years since the Canberra-based franchise last tasted finals rugby and White said his team would be taking its opportunity.
"The Bulls present us with a huge challenge this weekend," he said.
"We know they will play through their forwards and use Morne [Steyn] to finish with points.
"They have a good record here at Loftus and for our players to experience running on in front of a full house of more than 50,000 people will be fantastic.
"They are a typical South African side, very big and physical with some quality finishers out wide so it's up to our players to combat that with our own game."
Saturday's clash with the Bulls is the second time the Brumbies have faced off against the men from Pretoria this season.
In round seven the Brumbies narrowly avoided a draw when they were awarded a penalty after the siren, eventually winning 23-20.
Last time the Brumbies played at Loftus Versfeld was in April 2012 when despite outscoring the Bulls five tries to two, the Brumbies still went down 36-34.
Steyn booted 23 points that night - including seven penalties - leaving the Brumbies under no illusion as to how important infringements will be in this upcoming fixture.
Along with the Brumbies, who have a record of winning seven from eight finals matches at home since 1997, the Bulls have emerged as another side difficult to move during post-season rugby and are undefeated at home with five from five.
Should the Crusaders be able to knock over the Chiefs on Saturday night, the winner of this encounter will host the Final next Saturday.
