It is the territory's first new case in seven days, bringing the ACT's total number of cases to 104.

However, 91 of those cases have recovered from the virus and have been released from self-isolation. There are currently 10 active cases in the territory, one is in hospital.

The new case is a man in his 40s who acquired the disease overseas.

There have been almost 7000 negative tests in Canberra.

ACT chief health officer Dr Kerryn Coleman reaffirmed Canberra was in a "very strong position".

"We need to keep this effort going to make sure we don't get a fresh spike in cases that could easily turn into the types of numbers we see in other parts of the world," she said.

"I thank Canberrans for their efforts so far and I remind them that their responsible actions are helping to save lives."

"With another long weekend coming up I again ask people to be responsible and to stay at home," she said.

"Anzac Day is an important day for Australians but large gatherings or trips away are simply not possible this year.
