The Force welcome back their Wallaby contingent of Ben McCalman, Hugh McMeniman and Nick Cummins when they host the Brumbies on Saturday.
McCalman, who featured for the Wallabies in their recent Test series against the British and Irish Lions, will line up in the number eight jersey alongside captain Matt Hodgson and openside flanker Chris Alcock in the back-row.
McMeniman returns to the second-row having started at blindside flanker in the Force's last outing against the Waratahs four weeks ago.
Cummins makes his first appearance for the Western Force since the side's Week 14 clash against the Sharks at nib Stadium. The 25-year-old will start on the right wing forming a back three combination with Jayden Hayward and Pat Dellit.
James Hilterbrand earns his first Super Rugby start at hooker, replacing Heath Tessmann who has been ruled out with a hand injury, while Junior Rasolea replaces Kyle Godwin at inside centre, with the 20-year-old undergoing shoulder surgery during the June Test break.
Saturday's game will be the second time the Force has played the Brumbies following their 41-7 loss in Canberra in Week 11.
Head Coach Michael Foley says his side is determined to finish their 2013 campaign on a positive note.
"Saturday night represents an exciting challenge, which we've worked hard for over the last three-and-a-half weeks," he said.
"As a team, we've built a solid foundation based on character. Playing for each other and our people at home means a lot to us and we're determined to demonstrate that in our last match of the season.
"We have a great deal of respect for the Brumbies and recognise that playing with an aggressive mindset for 80 minutes is imperative against the Australian Conference leaders."
