A new health direction was issued on Friday afternoon in reaction to the Queensland government's decision to enforce a three-day lockdown for Greater Brisbane.

ACT Health has advised anyone who has returned from Greater Brisbane since January 2 to immediately isolate and get tested if they develop symptoms.

It follows the discovery of the UK variant of coronavirus in a cleaner at a Brisbane quarantine hotel.

United entered Queensland on Wednesday, before battling out a one-all draw with the Brisbane Roar at Dolphin Stadium the following night.

Traveling players and staff returned to Canberra on Friday afternoon, with their flight departing Brisbane before the city entered lockdown at 6pm.

"Our scheduled departure is before the 6pm lockdown announced by the Queensland government on [January 8]," a club statement said.

"On arrival into the ACT, staff and players will enter self isolation per ACT Health regulations.

"We understand ACT Health will reassess the situation in three days and make appropriate changes if necessary."

United is slated to meet the Newcastle Jets at McDonald Jones Stadium on Sunday, January 17. But those plans could be thrown into disarray if Canberra is required to complete the full 14-day quarantine.

Sunday's A-League clash between Brisbane and Melbourne Victory has already been postponed in response to the latest coronavirus developments in Queensland.

The rescheduled match is the latest impact of the ongoing pandemic on football, with both the W-League and A-League draws having had multiple adjustments to account for travel restrictions.

United played three matches in nine days under the revised schedule, with Linton's outfit overcoming the challenge to secure two wins and a draw.
