Western Force will travel to Darwin to face the Brumbies before returning to host a Tongan Select XV in Mandurah in two pre-season fixtures next month.
The games will provide the public's first chance to see the Force's new-look line-up in action under the tutelage of the squad's new coaching staff.
The Western Australian side will head to the Northern Territory to face the Brumbies on Friday, 1 February - the second successive year in which the two sides have squared off in pre-season.
Western Force will then return to Perth to take on a Tongan Select XV on Friday, 8 February at Meadow Springs Sporting Ground - home of the Mandurah Pirates. The visiting side will be made up of non-contracted Tongan-eligible players from Australia, New Zealand and Tonga.
Western Force head coach Michael Foley said both matches will provide a stern test prior to the start of the 2013 Super Rugby season.
"I've been pleased with the progress of our pre-season and these trials will provide a strong finish to our preparations ahead of our first game against the Rebels," he said.
"The Brumbies were one of the benchmark Australian sides last year and this is a good chance for us to test ourselves and our systems against one of the better performing teams of 2012. Likewise, the Tongan side will provide a solid final hit-out and no doubt a big physical challenge prior to our first game.
"I cannot fault the efforts of this squad during the pre-season and it's important that we maintain the standards we've set into the trials and the start of the Super Rugby season."
