ACT health authorities have warned Canberrans to monitor for Covid symptoms if they have travelled to Sydney since April 30, after a new case of community transmission was recorded.
A man in his 50s from Sydney's eastern suburbs tested positive for COVID-19 on Wednesday.
The man has no links to hotel quarantine, with urgent genomic testing under way by NSW Health to determine if the case is linked to others in the hotel quarantine system.
Health authorities in the state have said the man had not recently returned from overseas and did not work in hotel quarantine or had any contacts with NSW hospitals.
NSW Chief Health Officer Kerry Chant said the man had visited a number of locations in Sydney last weekend while infectious, including a cinema at the busy Westfield Bondi Junction shopping centre, several barbecue shops in Sydney's west and inner-west, along with a restaurant in Sydney's east.
We will continue to monitor the situation in NSW closely.
ACT Health spokesman
A full list of exposure sites is available on the NSW Health website.
ACT residents who have visited any of the venues have been ordered to get a Covid test and quarantine for 14 days from the time they visited the exposure site.
Travellers who have returned from Sydney have been urged to check the NSW website regularly, with new locations expected to be added.
"ACT Health will be adding these new exposure locations in NSW to the COVID-19 areas of concern notice," an ACT Health spokesman said.
"We will continue to monitor the situation in NSW closely and further respond if required.
"The situation is a reminder that COVID-19 is still with us. Please remember that things can change quickly."
NSW Premier Gladys Berejiklian said it was likely that more Covid cases would be detected following Wednesday's new case.
"Our response would be proportionate to the number of cases that are established, the geographical locations of the cases and whether or not they are in isolation," she said.
"We have to maintain our social distancing. We have to make sure we have very good hand hygiene. We need to get tested with the mildest of symptoms."
NSW Health said the man's two close family members had tested negative for COVID-19, while other family members were waiting on results.
Ms Berejiklian said the man had used QR codes to check in to venues.
"This person did everything right, but it goes to show we can't take anything for granted," she said.
