)The ACT has recorded one new case of COVID-19, a male aged in his 20s who is a close contact of a previous infection.
There are now five active cases of the virus in Canberra, all of them in hotel quarantine after flying into the national capital last week from Singapore.
ACT Health confirmed the latest case arrived with his family on the Government-facilitated repatriation flight on March 1.
They said he was related to a female in her 40s and a male aged under 20 who tested positive to the virus last week.
All three family members were moved to a separate part of the hotel when the two other cases were recorded.
Health authorities had anticipated new cases of the virus, given that others had been exposed to the infected people while travelling.
ACT Health said the five individuals who had so far tested positive were "well at this time and continue to be supported by ACT Health".
The first two passengers to test positive — a man aged in his 40s and a teenage boy — were confirmed to have the South African variant of the virus.
Whole genome sequencing is underway to determine the origin of the virus strain in the two people who tested positive on March 7.
The five cases were among 146 people who travelled on the Singapore Airlines flight, and close contacts of the new cases had already been told they would have an extended stay in quarantine.
ACT Health said hotel staff were following strict rules around the wearing of protective clothing and infection control processes.
They are also participating in the Safeguarding Canberrans program, which includes daily symptom screening and regular COVID-19 testing.
AstraZeneca vaccine rollout begins

)Phase 1A of Canberra's vaccination program is now more than half-way through, with 2,382 doses so far received among frontline health workers.
A total of 4,000 people were identified as being in the first phase of the vaccination rollout.
And Canberrans this morning started to receive the AstraZeneca vaccine, after its approval last month for use in Australia.
Among the first to get the jab was Canberra Health Services' Nick Coatsworth, one of 250 people expected to receive the dose this week.
Previous recipients were given the Pfizer vaccine, which was approved by the Therapeutic Goods Association earlier this year.
Oncologist and the Canberra Hospital's Cancer Centre clinical director Paul Craft was also vaccinated.
"I think the most important thing is to get vaccinated as soon as you can, as soon as it's available to you," he said.
"Both vaccines seem to work quite well — either one is way better than none at all."
Ms Stephen-Smith said it was a welcome step to have two vaccines available in the territory.
"I'm sure that people may have preference for one over the other — what I would say is that both vaccines are safe and both vaccines are effective and we're certainly seeing that increasingly from the international evidence," she said.
