ACT health authorities will manage quarantine for the returning officials but say the federal government should establish a fit-for-purpose facility for their overseas arrivals.

ANU deputy vice-chancellor Professor Ian Anderson confirmed on Monday afternoon a group of vaccinated, Australian officials would begin 14 days of quarantine from Tuesday.

"The ACT and federal governments have requested our assistance to safely quarantine groups of returning, vaccinated, official Australian travellers," he wrote in a letter to students and staff.

About 40 people stayed at the university's Davey Lodge last month, after returning from the G7 summit.

The ANU had lauded the Davey Lodge quarantine operation as a "workable and safe" model for future use.

However, going forward, travellers will stay at ANU apartments on Liversidge Street.

Davey Lodge will instead be retained for returned students who need to isolate, including domestic students caught up in COVID-19 outbreaks in Sydney and Melbourne.

"ACT Health and ACT Policing will oversee the quarantine. Quarantine arrangements in the ACT have been very successful, and we are confident they have very robust measures in place," Professor Anderson wrote.

The number of people returning to quarantine would vary from group to group.

An ACT government spokeswoman said the "most suitable accommodation facilities available" would be chosen for each intake of government officials who weren't undertaking home quarantine.

"Site selection will be based on the circumstances of each intake," she said.

"The ACT government's strong preference is for the Commonwealth government to establish and manage a dedicated and fit-for-purpose quarantine facility in the ACT."

The spokeswoman said more than 30 health staff would be involved in the operation, which would run similarly to hotel quarantine.

Travellers will be tested for COVID-19 several times throughout their stay and onsite staff will check in on their wellbeing.

"We continue to work closely with the Commonwealth government and the ANU to ensure there are strict processes and measures in place to protect the health and safety of passengers, staff and the wider Canberra community," the spokeswoman said.

"Robust infection prevention and control measures will be in place at the accommodation facility."

The apartments were previously used for visiting staff and are currently vacant.

ACT Chief Minister Andrew Barr has previously said the Commonwealth government should consider building a purpose-built quarantine facility in the ACT if there is going to be an ongoing need to quarantine returning government officials.

"It's the Commonwealth's responsibility principally around being able to manage their own staff and their own issues, but they need to work with us on those matters," he said last month.

"They are encountering, or had encountered, some of the same issues that we have, there's limited quarantine facilities in the ACT."

ANU has pushed for international student arrivals to be able to quarantine on campus, but ACT Health has previously deemed the accommodation unsuitable.

In a review into Davey Lodge, there were concerns around the lack of balconies and kitchen and laundry facilities in rooms.
