This is in stark contrast to one month ago.
On April 1 there were 75 active coronavirus cases in the ACT. At that stage a total of eight people had recovered and there had been one death.
How did the ACT come to having no cases and what happens next?
How did the ACT come to have no cases?
Canberra recorded its first confirmed case of COVID-19 on March 12. Two weeks later, on March 26, this case was confirmed as the first recovered case of the virus in the territory.
But in that same period 52 people had been diagnosed with coronavirus.
In the five days following the first recovery, only two further people had recovered but in early April the number of people who had gotten better started to grow rather rapidly.
The number of recovered cases surpassed active cases on April 9, with 54 recoveries and 48 active cases.
By April 24 there were just five active cases left in the ACT, and chief health officer Dr Kerryn Coleman said she was confident the territory would soon have no active cases.
On Thursday, Dr Coleman's prediction came to fruition as it was declared the ACT had no active cases, with 103 people recovered and three deaths. That remained the case on Friday.
Where did the ACT's COVID-19 cases come from?
More than three-quarters of the territory's cases were acquired overseas.
Since March 15, when Canberra had only one active case, all returning international travellers were required to self-isolate for 14 days, which meant these cases had little opportunity to spread the disease through the community.
Australian National University infectious diseases physician associate professor Sanjaya Senanayake said this was one of the keys to Canberra's success.
"I think restricting and monitoring people who travelled overseas was really important," he said.
"We've had some advantages, even though we have an international airport there is only limited international travel compared to the hubs you have in Sydney and Melbourne
"But as you well know, in Canberra we still have lots of people that travel overseas, Australians who are public servants and DFAT and defence."
Sixteen per cent of cases came from a close contact and 6 per cent of cases were acquired interstate.
There was one case of community transmission in the ACT.
Has the virus been eliminated in the ACT?
Short answer, no.
While the virus is still active within Australia, particularly in neighbouring NSW it's not possible to say its been eliminated.
As restrictions ease, associate professor Senanayake said: "it's more likely we will see a case".
Asymptomatic cases may also be present in the community.

Will asymptomatic cases have an impact?
This is one of the biggest dilemmas facing governments and health authorities as restrictions start to be lifted.
There is also the risk of pre-symptomatic people, those who are carrying the disease but do not yet show symptoms.
Dr Coleman said it was accepted there would some people who were either asymptomatic or pre-symptomatic but she did not they were making much of an impact.
"At this point in time we think there are a portion of people who are asymptomatic or may actually be pre-symptomatic," she said.
"But we don't think those cases are playing an important role in driving the pandemic."
Associate professor Senanayake said estimates on the number of asymptomatic cases in places across the world had differed across studies, these had ranged from 18 per cent to 77 per cent.
But he said it was unlikely asymptomatic patients were a big driver in transmission, nor were they very present in the ACT.
"The thing with asymptomatic is most of them went on to develop symptoms, even if they were asymptomatic at the time they had their test done," associate professor Senanayake said.
"The other thing is how important are they in transmitting infection, I think they can transmit infection, that's my suspicion but they don't do it as effectively as someone who has symptoms.
"That being the case if there were asymptomatic people who could transmit infection to other people... I would have thought we would still be seeing lots of cases in the ACT popping up."
What's next?
While there are no cases in the ACT, associate professor Senanayake warned against complacency.
"People need to realise we have won a major battle but we haven't necessarily won the war and quite naturally, and unexpectedly there will be people who've been suffering under their war of attrition in isolation," he said.
"Now with the restrictions being lifted will have a sense of euphoria that might go to the other extreme so it's to important to emphasise that we maintain social distancing while we can."
