The Brumbies were scheduled to play the Perth-based Western Force at Viking Park on Saturday, in what was meant to be their final hit-out before their Super Rugby campaign begins on February 19.

But Perth has started a five-day lockdown after a quarantine hotel security guard tested positive for COVID-19.

ACT Chief Health Officer Kerryn Coleman has declared Western Australia's capital a hotspot, with arrivals who have been in Perth since January 25 required to enter self-quarantine until Friday.

The Force were expected to land in Canberra later this week before playing a trial match at Viking Park on Saturday night.

ACT Health is aware of the fixture, but Coleman said they're yet to work through the situation.

"They have an exemption granted for the event to take place, however we have not taken stock yet of this new information," Coleman said.

"So we need to reassess and see whether they'll be any changes to that or not."

The COVID-19 threat and related border restrictions forced officials to wind back trials to one hit-out per Super Rugby AU club.

Brumbies prop James Slipper said it's important for players to get a match under their belts before round one, but the team would overcome the setback if the trial is cancelled.

"It's important [to play a trial match] but it's not the end of the day," Slipper said.

"Most players like to get a hit-out at some stage before round one, that's the ideal picture. But in saying that, these days whatever happens, happens.

"We'll make sure we're ready for round one of the competition, but ideally we want to play this weekend.

"Fingers crossed it goes to plan, a fair bit of water has to go under the bridge.

"We've just been concentrating on making sure we play good rugby this weekend and most of the boys get a run, that's probably the most important thing."

The Brumbies were expected to finalise their preparations in Canberra, before flying to Perth for their season opener in two weeks.

Western Australia has implemented strict border shutdowns since the start of the pandemic last year, leading some Brumbies players to move from their NSW homes to ACT addresses to ensure they would not be denied entry to the state for round one.

Rugby Australia, Brumbies and Force officials are expected to discuss the implications of the WA lockdown this week to determine if the game will go ahead in Perth.

The Force, who had been exiled from Super Rugby but returned last year, played all of their home games last season on the eastern side of Australia to avoid any border dramas.

ACT Health could lift its restrictions on Perth travellers by Friday, but it would not leave enough time for the Force to arrive and prepare for a match.

Western Australia government officials hope a snap lockdown will lead to no community transmission, which would allow travel to reopen later this week.

If there is a cluster associated to the hotel security guard, it could force Rugby Australia to shift the Force's season-opener to Canberra or a neutral venue.

Slipper said the Brumbies are prepared to deal with fixtures changes, having overcome the challenges thrown at them last season.

"I wouldn't say it fazes the group, last year was a good test of character and we just had to adapt," Slipper said.

"It wasn't just in rugby, it was in all sports across Australia and the world. It's nothing we're new to this year, we just have to make sure we're ready to go."
