Allan Alaalatoa and Lonergan brothers, Ryan and Lachlan, have moved into Canberra so they'll be ready to launch the Brumbies' title defence against the Western Force in Perth on February 19.

Western Australia's border is still firmly closed to NSW following Sydney's Christmas outbreak of COVID-19, with arrivals from the 'low-risk' state required to self-quarantine for 14 days.

The ACT is considered a 'very low risk' to WA, meaning its residents do not have to quarantine upon arrival.

"That's the political side isn't it? We need to make sure we keep the Western Australia Premier happy, so we've done that," Brumbies coach Dan McKellar said.

"It's a little adjustment for a few of our players but nothing major."

The COVID-19 pandemic has forced Super Rugby AU clubs to wind back to one trial each, with McKellar's outfit to host the Force at Viking Park on February 6.

The teams will play 30 minute thirds and the Brumbies will look to give the majority of players time in preparation for round one.

Selection for the hit-out will be finalised in the coming days, with McKellar likely to field a strong team with the club's Wallabies players back in action.

"We don't want to overload players so most guys will get a minimum of 20 minutes, and we've got a couple of guys that won't be selected but we'll finalise that over the next couple of days," McKellar said.

"It's about getting guys ready for round one, and some guys need more minutes than others.

"It's a big hit-out for both teams and we don't take a lot from the result. It's about putting into practice what we've worked hard on for the last couple of months and ideally making sure we have everyone to pick from for two weeks' time."

The Brumbies contested an internal scrimmage through rainy conditions on Friday, where players competed in scenario-based training at game intensities.

The alternative sessions will help McKellar narrow down his options for the Brumbies' season-opener, with three weeks left until kick off.

"[Selection] is always tough, which is why days like today when you're going against each other are really important that you take that opportunity," McKellar said.

"Then against the Force next week. It's about seeing our game in action and seeing the individual chance for guys to push for selection because there's always competition.

"[The scrimmage] was a good opportunity for the younger boys who have been working hard for eight weeks to put their improvements into a game scenario. There were plenty of good things."

The Brumbies also unveiled their 2021 playing kit on Friday.
