The ACT has had its busiest period of testing for coronavirus since February, as the territory remains free of active COVID-19 cases.
There have been 494 negative tests received in the past 24 hours and 379 the previous day, bringing the ACT's total tests to 16,962.
The ACT has remained free of active coronavirus cases for 24 days.
There have been 107 cases in the territory. 104 people have recovered and there has been three deaths.
"The past 48 hours has been our busiest period of testing since we began local testing for COVID-19 in the ACT in February," ACT Chief Health Officer Dr Kerryn Coleman said.
"A significant portion of our high test figures over the last two days has been from testing conducted on our returned Australians who have been in hotel quarantine since last Friday."
Dr Coleman said the decision to conduct voluntary testing for returned travellers, who finish their quarantine periods tomorrow, was based on the national guidelines.
"Although it has been over three weeks since our last active case in the ACT, I remind the community that testing remains the best way for us to know if COVID-19 is active in the community," she said.
"If you're feeling unwell, please get tested. Either call your general practitioner or present at one of the designated testing sites.
"Symptoms can vary between patients. The most common symptoms can include fever, shortness of breath, sore throat and cough. Additionally, sudden onset of loss of smell, loss of taste, runny nose, muscle pain, joint pain, diarrhoea, nausea, vomiting or loss of appetite."
